Hey, Tony, I made that arc furnace, too. It was in the 1955 Popular Mechanics encyclopedia. Used a clay pot, a pair of carbon arc electrodes, my mom's clothes iron as a load resistor in series with the arc. The clay pot was lined with a mixture of shredded asbestos and sodium silicate solution ("water glass"). I built a lot of stuff out of that set of books. One project was a wood lathe that I built in wood and metal shop class as a freshman in high school. I survived childhood, too. But just barely. My parents had no clue what I was up to most of the time. Still tinkering...
"Basic Electronics" magazine published a collection in the 60's. It includes a clay flower pot arc furnace that used two carbon rods from standard zinc/carbon 'D' cell batteries. No ballast. I melted a 4d finishing nail with it and couldn't see much of anything for about an hour. Before you ask, I checked it out of the library so, if I still had it, I'd be facing 80 years in prison and a visit from the Library Police.
I grew up with this Popular Mechanics Encyclopedias. I would go to bed and flip through them volume by volume before going to sleep each night...and then start over for years. I was around 10 years old at the time. Mom still has them on her book shelf. When she asked what I would like from the house when she goes I said that collection of books...she told me to take them now so I'm looking for a space in my 667 sqft house to put them. :-)
Most of the 1955 (I guess) Popular Mechanics Encyclopedias are available at archive.org/ and the Elecric Arc Furnace is among them available at archive.org/details/PopularMechanicsEncyclopediaSet/page/n255
3 1/2 years into a mechanical engineering degree and that’s some of the best CAD advice I’ve ever heard. Wish I wasn’t 5 years late to the party. Thank you ToT
Sorry for the re-upload. TOT not smart. I regret losing all the great comments. To answer some of the questions from before: - I use Fusion 360 for CAM because its offers free 3D toolpaths to hobbyists. HSMXpress (in Solidworks) only does 2D for free. - I use Solidworks because ... old dog / new tricks. Am just very used to it. Change = Scary. - 2D Contour in Fusion does have a chamfer option but, even checked, the toolpath wouldn't do collision / avoidance with the model. It just chamfered everything in its way. 2D Chamfer, on the other hand, is smart enough to raise the tool if the tool body is about to run into something. (note the "middle finger ring" isn't chamfered inside all the way around. If the chamfer tool path hadn't stopped, it would have cut open the bottom of the valve bore).
TOT, you should make the switch to fusion, it really is more better... :D I made the switch to fusion about 6 months ago, and i'm definately still learning the innards of it, but from a cad / cam standpoint, for me, it's just so much more intuitive, and robust. John Sunders over at NYCCNC puts out quite a bit of fusion related videos, enough to give you a decent start anyway. As for your chamfer issue, you could have "projected" the edge gemoetry, and edited the projected path to avoid your problem area.
SW is far superior to anything Autodesk puts out. I never liked AD and I tried F360 with the same results so stick with what you know as changing for the sake of changing, or to jump on the bandwagon because all of the cool internet kids are using it, is just plain dumb. Peace.
Wow! It just got brighter in here. (Inside my head, that is.) I went straight over to FreeCAD and made a square plate with a hole in it. Up until now I had absolutely no idea what "parametric modelling" was, let alone how it worked. Thank you Tony. I'm now a better man.
I'm just starting to learn Solidworks. I can't tell you how much I would love a series of Solidworks tutorials using the design of your gizmo (or some other moderately-complex gizmo with multiple parts). Watching you zip around the software, I could tell there'd be a ton of tips, tricks, techniques, and basics about using Solidworks that I'd learn. Please put that series together in your spare time.
I second that - as if you have any 'spare' time I know what having 2 sons is all about - we all barely survived their childhood, they are 30 and 31 now but it seems like just last week we were all in our teens LOL
I’m retired but that was one of the best tutorials I have seen I learned original AutoCAD through 12, some silver screen And I actually understood what you were talking about thank you for the knowledge
I'm having such deja vu and flashbacks right now, wishing I could remember verbatim what I commented last time around. Something something thank you for teaching me about keeping master sketches as a separate parts document.
I would love to see some more CAD related videos once in a while. With your way of explaining things the video doesn't even seem to be as long as it is 😊
"Sandpaper app" was the best part. Honestly I watch your content for entertainment, but they definitely inspire. Finally looking to buy my first mill or lathe this winter. The jokes you put in your videos are icing on the cake
Wow. Great description of design intent and parametric modeling. One of the reasons I fell in love with solidworks so many years ago as a real Design program and not just a digital drafting program. Using one design input parameter to update the entire design accordingly is critical for maintaining the integrity among many files and features. I really like the way you explained it and showed the clear connection and value.
As a recent recipient of one of these knuckle dusters I am very proud to own something that was a collaboration between makers that I admire. Love you guys.
Although I am a FreeCAD user, I've learned probably the best CAD lesson ever from this video: master model / parts / assembly workflow (21:36). I was always struggling creating multi-part parametric designs, but after using that workflow in the recent project I am really impressed how well did it go, Thanks, Old Tony!
I've been working with Solidworks for many years for my bike builds, up until now I've been manually deriving individual parts from a master drawing, and any changes to the master I've had to manually go through and correct, usually missing one small dimension and getting the dreaded "Rebuild errors" box invading my personal space. You, Sir, have literally saved me HOURS of time that I can now spend drinking beer or welding stuff together. THANKYOU!
I really appreciate the videos, you never know where your next inspiration or insight will come from. Old dog-new trick is apropos as it relates to cad, the video, and myself. I have been working with cad for 20+ and 3-d cad for close to the same. I have continued to use my self taught process. Watching the master modeling and realizing all the time it would have saved me over the years-well lets just say it hurt a little. I have known about i-parts and driven parts for a long time, but never pursued actually learning how to accomplish the feat, not sure why, just jump in and start designing I guess. I am not sure how it relates directly to inventor, possibly doesn't, but my curiosity is peaked and I feel it is the next step in my evolution with CAD. I did recently get the latest and greatest autodesk super suite, which includes CAM. It barely fit on my local drive and I will need to do some housekeeping seeing as how I have 3 versions of everything on my system at this point. I would be grateful for direction to literature or other training on master modeling. Also, and most important, thank you for sharing. The magnitude of skills and training being amassed on UA-cam alone is staggering not to mention the rest of the net. I use many UA-cam videos as training aides for technicians, there is no substitute for master training you can find online when you do not have in house masters. I love to teach and share myself and always hope what I teach transcends generations, also why I try very hard to make sure I am passing good information. When I look at what is available today, it gives me hope that we will bring skill back into the workforce and ingenuity back to the common man, those garage breakthroughs can change the course.
Hey Tony! I've been binging your videos the last few days. Wanted to write a comment on this one specifically for a few reasons! First off thank you! This is some seriously fantastic info wrapped up into a nice 30 minute package. I am going to school for mechE and we spent a quarter on CAD and design and didn't even touch on the idea of a "master" file. Next, well, I guess thanks again for all the cool stuff you cover on the channel! It's really inspirational and makes me want to scratch that creative maker itch! Cheers, Daniel
Its a couple years later and Im sure glad you made this video! Im one of those guys who learned AutoCAD when it was pretty new, all Dos based and command line oriented. I used just about every release from R2 to 2004 and did a lot of solid modeling to show non English speaking welders what I wanted them to make. Now im getting old and rarely draw but just bought a CNC router and need to get my cad skills back in order and add CAM to the list. Sure am glad there is UA-cam help to be had! Thanks Tony!
I think this is my favorite video of yours that I've watched so far. I mentioned once before, in another vid, that I worked in tool design. When I was in the field everything was drawn in 2D and you created "surfaces" where needed. After all the jobs when to China and Mexico I was out of the field for 10 years. My wife and I moved around chasing work in her field and I hoped we'd land somewhere where the economy was better and maybe enough manufacturing was going on and I might get lucky and get a job in my field again. It didn't happen so I took some cad classes to refresh. The semester I started we used AutoCAD 2011 and ended with the very end of version 2012. I was able, as a student, to download 2013 and Inventor but I was really only able to use AutoCAD in solid modeling space. So about 2 1/2 years ago, due to some political change, the economy improved greatly and I again tried to get back into the design field. AutoCAD isn't the go to cad program anymore. I think Solidworks might be the most common, which brings me to my point. I was able to follow along pretty well while you were using Solidworks, and between watching you and the hundred or so other videos of people using it and quite a few tutorial videos I think I could easily teach myself Solidworks and probably Mastercam without spending a bunch more money on college tuition. So, do you have a full "business" version or is there such a thing as a "hobby" version and about what would it cost me for what you have now? Also I hadn't heard of your cam program and I'm wondering if Mastercam might have a more connected interface between the two. Have you tried maybe a demo version of Mastercam by chance or are you experienced with it in some way? Thanks, and as usual, great vid!
Used SolidWorks professionally for 10 years. Your Master Parts and parametric explanations were super as is your fabulous visual techniques. I did diecast tooling design for ultrahigh frequency electronics.
I can not wait to apply the cad principles here. I used to find your channel entertainingly humorous and a release for engineering constraint, but with this video I have been truly inspired . thanks
Your videos are awesome! The editing is fantastic and I love the "dad" humor. I have four kids of my own, the oldest being 6, and they all love making things. I guess dad being an engineer is rubbing off on them. Your videos are full of inspiration, and I always look forward to your next upload. Thanks for spending the time to make such great content!
All i can say is - i wish you had been my instructor when i was young. You are an incredible instructor I actually want to listen to. If you ever want to create some “inventtions” that solve real world problems - rather than filling the air (and someones lungs) with particulates - let me know. I work for a high efficiency home builder and we have challenges no one has addressed.
my dude: your videos are concise and thoughtful and smart, and clearly illustrate concepts that can be super hard to try to wrestle from textbooks written by/for engineers. specifically, your thoughts on design intent! i appreciate a lot that you take the time to make these things. you're an internet goodguy, thanks for doing what you do!
Tony, Thanks for showing us how to take a sketch and flesh it into a 3D model. I look forward to seeing you go from prototype to final product!!! You are a great teacher!!!
Unbelievable, what an awesome tutorial! been fiddling with Solidworks for 7 years now and still not even close to having such a clean workflow, incredible. Id love to see more tutorials since this is by far one of (if not) the best tutorials i've ever come across on Solidworks! Only found this channel today and you sir, are already my favorite. What can't you do?
I just found you. I'm nerdy in love with your videos, and can't wait to watch them all. I was a machinist for ten years, and it's hard to find just the right amount of technical savvy and wtf dad humor to make it all worth it. Thanks Tony! :D
The How and Why series of books. I ran across the one on Electricity in about 1965, inside of a few months I was lighting flashlight bulbs then 2 with DPDT switches. Then fuses made from Christmas tree Icles (real lead foil back then - incredibly shocking mix for the 120v 11w Christmas lights on the tree.... In any case I had my amateur ticket at 13, was working part time at a TV shop repairing TVs from 13 thru college. One day, standing in a 40,000 sq ft IBM cleanroom - I was part of building the process equipment, I thought of that book. It changed my life. I exposed my 2 sons (both in college now) to a lot of stuff growing up, but they never latched onto anything like I did. I never knew 'not knowing what I wanted to do". One of my sons is getting his marketing degree this year and the other is well along in his Mech Eng studies. He now gets my machine tools.... I did the pencil lead thing, stank to high heaven until the oils in the lead burned off. More of a resistance heater. The solenoid bedroom setup was just the solenoid brought to 2 screws about an inch and a half apart on the drawer face. The "Key was a 6 volt lantern battery - you just touched it to the screws. You could arc 'weld' with a large train transformer and steel wire.....
I wonder why the last generation of kids really flounder at what they want to do? It's like an over exposer to information has left them clueless... WTF 15 years ago it wasn't this bad. Now all they can do is use social media. Our kids are just in their teens.
I've been parametric modeling for almost 20 years and even I learned something from this master model technique. Glad to be back on Solidworks (2015) this go around so I'll definitely be giving this a shot. Thanks Tony :)
I use Solidworks every day at my job. Being self-taught, I never realized you could use a master part this way for this kind of parametric design! I HAVE done something similar, i.e. making a single, multi-body part which models the entire assembly, and then making configurations which use Delete/Keep body to isolate each part as its own configuration of the whole model. Your way seems like a more elegant way of achieving the same end. Thanks for going into so much detail! It's always nice to get a reference for how people use the tools I've sort of haphazardly thrown together my knowledge of.
Just found your channel and I'm hooked. Love the humour. As a mechanical CAD draughtsman for a little over ¼ of a century (starting on AutoCAD R9) I have to say that while parametric software like Solidworks and Inventor certainly have their place, unless you're going to be doing different versions of something based on different parameters but with the same design philosophy , it is just so much slower, especially when the customer rarely knows what the design intent actually is in the first place. Add to the mix the materials availability with changing dimensions and variants of the original need to accommodate that. And don't get me started on when the basis of the entire design changes and as you put it "you travel back in time" via the part tree and all the subsequent driven parameters affected by the change "disappear from your family polaroids" and you spend the next 6 hours chasing the resulting build errors through the other parts of the assembly and re-mating all the assembly constraints too. Sometimes new things just aren't better for all applications and the reality rarely lives up to the sales brochure hype.
I missed this one due to not enough hours in the day, the reupload was like a bonus notification in this case. Great video CAD has always been very interesting to me and you explain your process well.
Thanks TOT I am really enjoying your videos and I have concluded you are a very intelligent man and do some awesome work and I am very envious of the tools and machinery you have in your shop(garage) and amazed at the machinery you have built and the knowledge you have of the inter workings of your stuff. Keep on having fun and I will look forward to watching more. Thanks
Mr. T... please know I so geek out on this shtuff. I'm so glad to have found you, and being an analog IC guy, who's re-exploring mechanical and metal, ToT simply rocks my brain. Thank you, sir.
Meanwhile, I've been a SketchUp Pro user for a few years now, mostly for simple woodworking and... lets say... architecture/construction in the form of a very complicated post and beam barn (to be built in 2019). I have come to like and effectively use SketchUp, but have always wished it had true parametric capabilities. I recently joined the Ann Arbor Maker-Works maker space -- a wonderful non-profit w/ great people, a big heart and precious goals, www.maker-works.com/ -- and have installed Fusion 360 on my machine so I can export usable files for the Maker-Works tools. You seem to like, even promote F360, so I am now even more motivated to learn this software I supposes one question is: can Fusion 360 be used to create a similarly parametric Master Model in the same way as Solid Works? (You may have already answered this in the video. I'll re-watch, of course...) Thank you, Mr T !!
Great video; you obviously put a lot of work on the video content and editing. I liked the easy way you got across the idea of direct vs. parametric modeling. Thanks!
"Fun with electricity" A Frederick Collins 1936. My father had it when he was a boy, and gave it to me when I was 10. He also gave me a wooden Ford spark coil that I ran with my Marx train transformer. At least a decade later I would be hired by companies to draw schematics and then go to the lab and make them work by correcting the schematics with red ink.
I remember that one! My elementary school was built in the early 50's so that was practically cutting edge, even though I read it in the early 90's heh
I have been using 3D CAD for years. I must have seen this master modeling technique before, but cant remember it explained so clearly as here. Will definitely use it my next project. Thanks.
you're on a roll! Engineers Notebook and others by Forrest M Mims III from Radio Shack got me started. 40 plus years later and I still refer back to them from time to time.
I rewound it twice, finally slowing it to 25%, and lost it when I realized he got me again! It's almost like getting RickRolled at this point. Love it!
I change the dimensions of my CAD models by adding or subtracting layers of cardboard. Thanks for this video, Tony! I learned enough here to understand that I will never have the patience to learn all that. Ever. And that's valuable information :)
Tony, I have a couple of thoughts on your discussion of old "technology" books. My favorite when I was a kid (a looong time ago) was "The Boy Mechanic", a publication of Popular Mechanics and Simon and Schuster. It has about 500 projects of every kind. I remember building some of the electric motors and getting ideas for a lot of kites. I still have the book. My copy has copyright dates from 1913 to 1952. They do have your electromagnet lock in there, but applied to a door rather than a drawer. I made a carbon arc like you discussed. I can't remember where I got the idea, but my electrodes were the carbon center rods from used D size carbon zinc batteries that I tore apart. My source said that you needed a load resistor in series. I used my mom's electric iron for the load and when she saw how bright the light was she locked it away. Rats! Paul -- max runout on youtube
Hey Tony, I know this video is 2 years old and you probably figured it out already but if you want to machine chamfers that are modeled into the part, just select the top edge of the chamfer, set the width to 0, and give it a tip offset. I don't know if you need to do this step but under the heights tab, I set both the top and bottom height to the "selected contour" option. I believe this will give you a warning but it doesn't mean anything. Hope this helps!
First of all, great video, as usual! 10:53 You would be surprised! As much as I am when I propose a parametric CAD as a design solution and am told that the parametric workflow is slower and less efficient. I can almost feel static electricity in my head from my brain trying to compute the audio input... Bottom line is, there is every flavour of CAD out there and people like what they are used to. (Me included, I guess)
Years of SolidWorks and a CSWA certification and I never even thought to use a master model in the way you did. I don’t know why but that just never occurred to me and I would always tediously jump between files taking measurements. This made it click for me!
Hey Tony! I've been modeling things and designing parts, tools, moulds, machines with Solidworks for a couple of years now and this was the first I've seen a CAD-flow like that. I really like the idea, very straightforward and seems to work great. Sometimes in situations like you had with this part I've just started modeling an assembly. Basically draw my first main part, like the valve body and then start new part for each and every part and just model it directly on to the first part. That way I get parts parametric to each other, but there is some things it doesn't like and doesn't do and warns about doing. So definately not the best way, but works for small assemblies such as this valve :) The Fusion360 looks nice, but I still would go with SolidCAM as it works inside Solidworks and the iMachining in it Just.Blows.Your.Mind. Watching a clapped out old crap small mill just chooch stainless without messing around with any feeds & speeds calcs or figuring out the values is priceless (well, SolidCAM has a price, 5-ish-k and up). But literally, you just tell it what you want to machine, select the material, select your tool diameter/length and tell the helix angle (not necessary, but helps in chatter calculations/warnings) and hit OK and you have an adaptive tool path with constant chip load no matter what. Want to go easier/heavier? Just use an 8-point slider to select a new level of aggressiveness (is that a word?) and hit OK. Ah, long babling but anyways, thanks for thhe video, can't subscribe as I've already done that, so take care! :) With cold and snowy greetings from Finland, Jaakko
Hi Tony, Enjoy all your videos. Your fun to watch!!! love the knuckle dragging design of the air gun, I want one. Thanks for your time and knowledge on the cad,it's way over my head but your helping me to figure out what cad programs to look for. M.K.S.
0:17 Are you kidding? We're here for the small talk, joke's (dad joke's), machining, metal cutting, fab, welding, repairs, etc. I'm not putting any of the other UA-camrs down or anything, buy if I can't find anything to watch. I'll always go to ToT n rewatch your videos as they make me happy and relaxed. I'd say it's similar when watching TV. You look through the guild/listing n there's never anything new or interesting on. The only thing that is worth watching is a film you like because it's easy relaxing watching. And it's probably a BTTF, which everyone loves 😍
Thanks man that was a great solid works primer. Just wanted to say that although I loved the sandpaper app, I loved the pattern you sanded away more and saw it as quite texturally awesome to this graphic designers eye.
Good luck with that. I recall several books I actually owned, Science Experiments for Boys was one, and that also had projects ike arc lights from charcoal, Whimhurst machines from old 78 records and a hearth brush and the like. I'd love it now (I'd really be able to do some damage these days!) but though my mother denies throwing it out while I was out 'living my own life', I can't find it in my hundreds of books in storage and cannot even find reference to it anywhere online. Perhaps it was withdrawn by the authorities as too many kids overthrew regimes with it, but I'd love to have it again. Then again, perhaps my memory is screwed up, but seeing this video brought those longings back to front and centre. Thanks TOT.
I found an article on building a similar device in an archived magazine from the 1930s and gave it a try. It works, but I'd recommend using carbon rods from a lantern battery instead of pencil lead.
Haaha!! I absolutely love these videos. You are the man. I laugh out loud, and sometimes my ass off almost every video. Like the screen shot at 6:17. Keep it up man, awesome, awesome content. Never stop
I did something similar in 5th grade. We were doing experiments with batteries and small light bulbs. Then the teach dozed off at his desk. I started hooking up D batteries in series with electrical tap and running the current through mechanical pencil lead. It would proceed to heat up, glow, and melt through the plastic chairs. Not quite the full arc furnace, but just as fun.
Tony! Great video! Fantastic explanation on Master Modeling. I wish some of the large Fortune 500 companies I do design work for grasped and applied this principle.
At 6:16 ... Tony you have to strip the ends of the wire to insure good continuity, especially in a high current circuit like this one. Awesome design from a reliability standpoint.
Keen to try out you master sketch method as I haven’t done a lot of true parametric modelling. I have been mucking around with Solidworks for a little while now. I have the 2014 version, and really like it. Thanks for the video 👍🏼😎
My first introduction was a box of wires, switches, motors and light bulbs that, at twelve volts, not suseptable to blowout from the 4.5 volt batteries I was given. Next level was a Tandy experiment board, with lots of parts on a cardboard base with connection possible using springs. Next stage was an apprenticeship and 4 years of college. 😊
Still Brilliantly executed Edutainment TOTony and I was smarter this time not to abnormally aspirate my coffee while watching for the third time. The mix of design elements and design operations worked perfectly with your excellent cinematography. A nice dance with the music and the 4 up milling sequence! With the advent of CAD and Parametric modeling the old saying I was taught "Never draw more in the morning than you can erase in the afternoon" is heading for extinction I think...and now with CAM/3D Print it seems like Fusion360 is a step closer to a unified field theory were we might project our mind to create out of thin Ethers. I remember writing LISP with nut and bolt spreadsheet info and BOM output for ASSY's and it seemed like magic at the time...endless possibilities. The books I remember were Popular Science and Mechanics having sections for kid experiments back in the late 50' and 60's. The "Lady Bird Books" below looks pretty good though. Also the Forrest Mimms books were great for teaching my son basic electronics. This is a great format and hope you continue with more of these!! Big O' Thank You TOTony, well done to say the least! ~PJ
Me: No officer, it might have "Cali Commie AR 15 of doom" engraved on it, but it is an air blower. Cop: AR... ASSAULT AIR BLOWER! YOU ARE UNDER ARREST. You have the right to remain silent... .
sadly, that is the mentality of most people today... even on ebay if you try to list say a glue "gun", or a toy "gun", heat gun, soldering gun, ect ect ect.... it always gets flagged under their "vero" items simply because it contains the word "gun".... for many reasons, it is truly a sad and willfully stupid generation in which we live...
Re-uploaded and you didn't fix the units at 1:41? The OCD triggered my PTSD which in turn caused involuntary encopresis. Now I have a mess to clean up. Thanks Tony!
A Boy and a Battery by Yates! I still remember the smell of old books and early 90's optimism in my elementary school library, exhausting the 5-odd books they had on electricity
I always enjoy your videos. The editing work is really done well. If I may, I'd like to contribute (with all due respects of course) . During your final rendered motion animation, it looked like you had some handle to frame interference just behind the valve head in the area of the body radius and handle underside. Not a big deal. I would also say you may be looking at some soft tissue impingement ( pinching of skin on your hand) between the handle and body. A larger radius on the underside of the handle may solve that. You also did a masterful job of hiding the side to side profile mismatch during filming. Once you generated the holes and sculpted the body, you could have used buttons in those holes to secure the part to a plate for a full perimeter cut and not worried about a parting line remnant or mismatch. I do scuba light trays like this all the time and the technique is sound. Oh yea...one more thing...you forgot to engrave Diresta in 47 places on the body. As always, thumbs up.
Thanks Joe! The rendering wasn't the final CAD, I didn't get any pinching, and good tip on the buttons! I usually use the router to drill dowel holes for this kind of work, straight down into the fixture plate.
Whenever I am looking at a job like that, If I have a choice, I would rather put the potential mismatch on the chamfers than a profile surface. They can be out and its practically invisible. Thanks for the reply. Keep up the great videos. I always enjoy your projects.
The Dangerous book for boys is my go to gift for all my friends' kids' birthdays when they reach 9 or 10. My sons both got the book at 10 as well. I highly recommend it.
Thank you so much for this video. It is going to help so much with my solidworks design work for my degree so much. I only wish I learned this "master" concept before pouring way too much time into my design projects.
Amazing content. After AutoCad and Inventor, Solidworks in next in the schedule.. Looking forward to it and hope to see some more SW stuff from you. Thanks Tony!
My favorite childhood experiment was in 5th grade when we made dry ice artillery... later that week I started going into pressure vessels, leading me down a rabbit hole of various rocket motors, leading to aerodynamics, leading to full out amateur liquid fueled rocketry (thank you local rocket club)... later I moved to Indiana and am no longer able to do liquid fuel... so I now terrorize kerbals
I loved Popular Mechanics magazine when I was a kid. I actually had my own subscription :-) Lots of good info in those magazines though... at least there used to be... but like nearly everything else today, its probably been bought out by liberals and they probably only have "cup cake recipes" or "makeup advice for "boys"" or whatever in it now.... it is a sad sad thing to see just how far the last few generations have fallen, let alone the current generation... real men are getting fewer and fewer every day.
"Dangerous" is the chemistry books from the 30 and 40's. Some UA-camr has a few videos on replicating those formularies. He found the book in the school's garbage Dumpster.
@@Yhrim70 real men? Seems your totally full of male toxicity. I know two women who were doing those electronic projects from popular mechanics back then. One of those women was my mother. She was not afraid to try experiments with me. So bugger off with your "real men" statement.
@@troyna77 Very cunning, to play the "you are probably full of toxic masculinity, so shut up" card. Well, nothing prevents women from doing "boys things", should they choose to, except maybe overprotective parents. Stating that boys are no longer allowed/motivated to do "boys things" is nothing toxic. But all that is irrelevant, because you know exactly who is full of toxicity and therefore their opinion is no longer valid, right? I am Soooo glad to have you around... No, seriously, think of a better counter, see if you find one.
i used to have the exact book you describe. i can't be 100% sure but i'm almost certain it was written by alfred morgan (wikipedia lists him as alfred powell morgan) and i'm pretty sure it was called 'a first electrical book for boys'. i could be wrong on the title because morgan was somewhat prolific and some of his books had similar titles, and other books were republished with different titles. another of the projects i remember from that book was the jacob's ladder made from a model t spark coil. just in case a model t spark coil might not be available, he included detailed instructions on how to build one from scratch.
Superb presentation. I am too much of an old dog for this, though I use the minimal of plain CAD. As I see it the third O ring stops the air pressure helping the spring. Beyond this nice decorative piece, why would I use an air blower which is more difficult to pick up than any other? ????
Hey, Tony, I made that arc furnace, too. It was in the 1955 Popular Mechanics encyclopedia. Used a clay pot, a pair of carbon arc electrodes, my mom's clothes iron as a load resistor in series with the arc. The clay pot was lined with a mixture of shredded asbestos and sodium silicate solution ("water glass"). I built a lot of stuff out of that set of books. One project was a wood lathe that I built in wood and metal shop class as a freshman in high school. I survived childhood, too. But just barely. My parents had no clue what I was up to most of the time. Still tinkering...
You still have that collection of books?
"Basic Electronics" magazine published a collection in the 60's. It includes a clay flower pot arc furnace that used two carbon rods from standard zinc/carbon 'D' cell batteries. No ballast. I melted a 4d finishing nail with it and couldn't see much of anything for about an hour. Before you ask, I checked it out of the library so, if I still had it, I'd be facing 80 years in prison and a visit from the Library Police.
I was born in the 2000's yes, but I rebuilt a snowmobile engine in my bedroom when I was 13
I grew up with this Popular Mechanics Encyclopedias. I would go to bed and flip through them volume by volume before going to sleep each night...and then start over for years. I was around 10 years old at the time. Mom still has them on her book shelf. When she asked what I would like from the house when she goes I said that collection of books...she told me to take them now so I'm looking for a space in my 667 sqft house to put them. :-)
Most of the 1955 (I guess) Popular Mechanics Encyclopedias are available at archive.org/ and the Elecric Arc Furnace is among them available at archive.org/details/PopularMechanicsEncyclopediaSet/page/n255
3 1/2 years into a mechanical engineering degree and that’s some of the best CAD advice I’ve ever heard. Wish I wasn’t 5 years late to the party. Thank you ToT
Sorry for the re-upload. TOT not smart. I regret losing all the great comments.
To answer some of the questions from before:
- I use Fusion 360 for CAM because its offers free 3D toolpaths to hobbyists. HSMXpress (in Solidworks) only does 2D for free.
- I use Solidworks because ... old dog / new tricks. Am just very used to it. Change = Scary.
- 2D Contour in Fusion does have a chamfer option but, even checked, the toolpath wouldn't do collision / avoidance with the model. It just chamfered everything in its way. 2D Chamfer, on the other hand, is smart enough to raise the tool if the tool body is about to run into something. (note the "middle finger ring" isn't chamfered inside all the way around. If the chamfer tool path hadn't stopped, it would have cut open the bottom of the valve bore).
No worries, we will watch and comment some more! SUBSCRIBE!
Why did you not paint it white?
TOT, you should make the switch to fusion, it really is more better... :D
I made the switch to fusion about 6 months ago, and i'm definately still learning the innards of it, but from a cad / cam standpoint, for me, it's just so much more intuitive, and robust.
John Sunders over at NYCCNC puts out quite a bit of fusion related videos, enough to give you a decent start anyway.
As for your chamfer issue, you could have "projected" the edge gemoetry, and edited the projected path to avoid your problem area.
This Old Tony why'd you do it....? Curious as hell
SW is far superior to anything Autodesk puts out. I never liked AD and I tried F360 with the same results so stick with what you know as changing for the sake of changing, or to jump on the bandwagon because all of the cool internet kids are using it, is just plain dumb. Peace.
Wow! It just got brighter in here. (Inside my head, that is.)
I went straight over to FreeCAD and made a square plate with a hole in it. Up until now I had absolutely no idea what "parametric modelling" was, let alone how it worked.
Thank you Tony. I'm now a better man.
"order a small rock from Amazon" had me in stitches!

I'm just starting to learn Solidworks. I can't tell you how much I would love a series of Solidworks tutorials using the design of your gizmo (or some other moderately-complex gizmo with multiple parts). Watching you zip around the software, I could tell there'd be a ton of tips, tricks, techniques, and basics about using Solidworks that I'd learn. Please put that series together in your spare time.
Assuming you may still be hungry for more... the internal tutorials are actually very good if you haven't taken the time to go through them.
I second that - as if you have any 'spare' time I know what having 2 sons is all about - we all barely survived their childhood, they are 30 and 31 now but it seems like just last week we were all in our teens LOL
I’m retired but that was one of the best tutorials I have seen I learned original AutoCAD through 12, some silver screen And I actually understood what you were talking about thank you for the knowledge
I'm having such deja vu and flashbacks right now, wishing I could remember verbatim what I commented last time around. Something something thank you for teaching me about keeping master sketches as a separate parts document.
Make more Kalimbas!
Same, same, something, something, brilliant video.
I would love to see some more CAD related videos once in a while. With your way of explaining things the video doesn't even seem to be as long as it is 😊
"Sandpaper app" was the best part. Honestly I watch your content for entertainment, but they definitely inspire. Finally looking to buy my first mill or lathe this winter. The jokes you put in your videos are icing on the cake
Wow. Great description of design intent and parametric modeling. One of the reasons I fell in love with solidworks so many years ago as a real Design program and not just a digital drafting program. Using one design input parameter to update the entire design accordingly is critical for maintaining the integrity among many files and features. I really like the way you explained it and showed the clear connection and value.
As a recent recipient of one of these knuckle dusters I am very proud to own something that was a collaboration between makers that I admire. Love you guys.
i love this man. his sense of humor makes me smile every time
Although I am a FreeCAD user, I've learned probably the best CAD lesson ever from this video: master model / parts / assembly workflow (21:36). I was always struggling creating multi-part parametric designs, but after using that workflow in the recent project I am really impressed how well did it go, Thanks, Old Tony!
This video fundamentally changed my work flow in a big picture kinda way. Thanks Tony!
I've been working with Solidworks for many years for my bike builds, up until now I've been manually deriving individual parts from a master drawing, and any changes to the master I've had to manually go through and correct, usually missing one small dimension and getting the dreaded "Rebuild errors" box invading my personal space.
You, Sir, have literally saved me HOURS of time that I can now spend drinking beer or welding stuff together.
THANKYOU!
These long videos explain design are priceless. You don't learn this kind of stuff in engineering school anymore. Thank you.
I really appreciate the videos, you never know where your next inspiration or insight will come from. Old dog-new trick is apropos as it relates to cad, the video, and myself. I have been working with cad for 20+ and 3-d cad for close to the same. I have continued to use my self taught process. Watching the master modeling and realizing all the time it would have saved me over the years-well lets just say it hurt a little. I have known about i-parts and driven parts for a long time, but never pursued actually learning how to accomplish the feat, not sure why, just jump in and start designing I guess. I am not sure how it relates directly to inventor, possibly doesn't, but my curiosity is peaked and I feel it is the next step in my evolution with CAD. I did recently get the latest and greatest autodesk super suite, which includes CAM. It barely fit on my local drive and I will need to do some housekeeping seeing as how I have 3 versions of everything on my system at this point. I would be grateful for direction to literature or other training on master modeling. Also, and most important, thank you for sharing. The magnitude of skills and training being amassed on UA-cam alone is staggering not to mention the rest of the net. I use many UA-cam videos as training aides for technicians, there is no substitute for master training you can find online when you do not have in house masters. I love to teach and share myself and always hope what I teach transcends generations, also why I try very hard to make sure I am passing good information. When I look at what is available today, it gives me hope that we will bring skill back into the workforce and ingenuity back to the common man, those garage breakthroughs can change the course.
Hey Tony!
I've been binging your videos the last few days. Wanted to write a comment on this one specifically for a few reasons!
First off thank you! This is some seriously fantastic info wrapped up into a nice 30 minute package. I am going to school for mechE and we spent a quarter on CAD and design and didn't even touch on the idea of a "master" file.
Next, well, I guess thanks again for all the cool stuff you cover on the channel! It's really inspirational and makes me want to scratch that creative maker itch!
Cheers,
Daniel
I do think the hinge pin needs to be stronger to cope with the forces it will encounter during a full power uppercut, right hook or haymaker
Its a couple years later and Im sure glad you made this video! Im one of those guys who learned AutoCAD when it was pretty new, all Dos based and command line oriented. I used just about every release from R2 to 2004 and did a lot of solid modeling to show non English speaking welders what I wanted them to make. Now im getting old and rarely draw but just bought a CNC router and need to get my cad skills back in order and add CAM to the list. Sure am glad there is UA-cam help to be had! Thanks Tony!
I think this is my favorite video of yours that I've watched so far. I mentioned once before, in another vid, that I worked in tool design. When I was in the field everything was drawn in 2D and you created "surfaces" where needed. After all the jobs when to China and Mexico I was out of the field for 10 years. My wife and I moved around chasing work in her field and I hoped we'd land somewhere where the economy was better and maybe enough manufacturing was going on and I might get lucky and get a job in my field again. It didn't happen so I took some cad classes to refresh. The semester I started we used AutoCAD 2011 and ended with the very end of version 2012. I was able, as a student, to download 2013 and Inventor but I was really only able to use AutoCAD in solid modeling space. So about 2 1/2 years ago, due to some political change, the economy improved greatly and I again tried to get back into the design field. AutoCAD isn't the go to cad program anymore. I think Solidworks might be the most common, which brings me to my point. I was able to follow along pretty well while you were using Solidworks, and between watching you and the hundred or so other videos of people using it and quite a few tutorial videos I think I could easily teach myself Solidworks and probably Mastercam without spending a bunch more money on college tuition. So, do you have a full "business" version or is there such a thing as a "hobby" version and about what would it cost me for what you have now? Also I hadn't heard of your cam program and I'm wondering if Mastercam might have a more connected interface between the two. Have you tried maybe a demo version of Mastercam by chance or are you experienced with it in some way? Thanks, and as usual, great vid!
20:36: UA-cam auto-caption: _"This is music."_
Me: Yes. Yes, it is.
Edit: Also, thanks for the CAD 101 lesson. Great advice!
Used SolidWorks professionally for 10 years. Your Master Parts and parametric explanations were super as is your fabulous visual techniques. I did diecast tooling design for ultrahigh frequency electronics.
I can not wait to apply the cad principles here. I used to find your channel entertainingly humorous and a release for engineering constraint, but with this video I have been truly inspired . thanks
Your videos are awesome! The editing is fantastic and I love the "dad" humor. I have four kids of my own, the oldest being 6, and they all love making things. I guess dad being an engineer is rubbing off on them. Your videos are full of inspiration, and I always look forward to your next upload. Thanks for spending the time to make such great content!
All i can say is - i wish you had been my instructor when i was young. You are an incredible instructor I actually want to listen to.
If you ever want to create some “inventtions” that solve real world problems - rather than filling the air (and someones lungs) with particulates - let me know. I work for a high efficiency home builder and we have challenges no one has addressed.
my dude: your videos are concise and thoughtful and smart, and clearly illustrate concepts that can be super hard to try to wrestle from textbooks written by/for engineers. specifically, your thoughts on design intent! i appreciate a lot that you take the time to make these things. you're an internet goodguy, thanks for doing what you do!
Tony, Thanks for showing us how to take a sketch and flesh it into a 3D model. I look forward to seeing you go from prototype to final product!!! You are a great teacher!!!
Unbelievable, what an awesome tutorial! been fiddling with Solidworks for 7 years now and still not even close to having such a clean workflow, incredible. Id love to see more tutorials since this is by far one of (if not) the best tutorials i've ever come across on Solidworks! Only found this channel today and you sir, are already my favorite. What can't you do?
thanks mickO!
I just found you. I'm nerdy in love with your videos, and can't wait to watch them all. I was a machinist for ten years, and it's hard to find just the right amount of technical savvy and wtf dad humor to make it all worth it.
Thanks Tony! :D
The How and Why series of books.
I ran across the one on Electricity in about 1965, inside of a few months I was lighting flashlight bulbs then 2 with DPDT switches. Then fuses made from Christmas tree Icles (real lead foil back then - incredibly shocking mix for the 120v 11w Christmas lights on the tree.... In any case I had my amateur ticket at 13, was working part time at a TV shop repairing TVs from 13 thru college. One day, standing in a 40,000 sq ft IBM cleanroom - I was part of building the process equipment, I thought of that book. It changed my life.
I exposed my 2 sons (both in college now) to a lot of stuff growing up, but they never latched onto anything like I did. I never knew 'not knowing what I wanted to do". One of my sons is getting his marketing degree this year and the other is well along in his Mech Eng studies. He now gets my machine tools....
I did the pencil lead thing, stank to high heaven until the oils in the lead burned off. More of a resistance heater. The solenoid bedroom setup was just the solenoid brought to 2 screws about an inch and a half apart on the drawer face. The "Key was a 6 volt lantern battery - you just touched it to the screws. You could arc 'weld' with a large train transformer and steel wire.....
I wonder why the last generation of kids really flounder at what they want to do? It's like an over exposer to information has left them clueless... WTF 15 years ago it wasn't this bad. Now all they can do is use social media. Our kids are just in their teens.
I've been parametric modeling for almost 20 years and even I learned something from this master model technique. Glad to be back on Solidworks (2015) this go around so I'll definitely be giving this a shot. Thanks Tony :)
Tony you're my favorite youtuber by a country mile. cheers buddy. I savour each vid.
I use Solidworks every day at my job. Being self-taught, I never realized you could use a master part this way for this kind of parametric design! I HAVE done something similar, i.e. making a single, multi-body part which models the entire assembly, and then making configurations which use Delete/Keep body to isolate each part as its own configuration of the whole model. Your way seems like a more elegant way of achieving the same end. Thanks for going into so much detail! It's always nice to get a reference for how people use the tools I've sort of haphazardly thrown together my knowledge of.
Just found your channel and I'm hooked. Love the humour.
As a mechanical CAD draughtsman for a little over ¼ of a century (starting on AutoCAD R9) I have to say that while parametric software like Solidworks and Inventor certainly have their place, unless you're going to be doing different versions of something based on different parameters but with the same design philosophy , it is just so much slower, especially when the customer rarely knows what the design intent actually is in the first place. Add to the mix the materials availability with changing dimensions and variants of the original need to accommodate that. And don't get me started on when the basis of the entire design changes and as you put it "you travel back in time" via the part tree and all the subsequent driven parameters affected by the change "disappear from your family polaroids" and you spend the next 6 hours chasing the resulting build errors through the other parts of the assembly and re-mating all the assembly constraints too.
Sometimes new things just aren't better for all applications and the reality rarely lives up to the sales brochure hype.
thanks Tony. you're completely right, this has a time and a place.
I missed this one due to not enough hours in the day, the reupload was like a bonus notification in this case. Great video CAD has always been very interesting to me and you explain your process well.
Thanks TOT I am really enjoying your videos and I have concluded you are a very intelligent man and do some awesome work and I am very envious of the tools and machinery you have in your shop(garage) and amazed at the machinery you have built and the knowledge you have of the inter workings of your stuff. Keep on having fun and I will look forward to watching more. Thanks
One of my favorite books from my childhood - the way things work by David Macauley
Mr. T... please know I so geek out on this shtuff. I'm so glad to have found you, and being an analog IC guy, who's re-exploring mechanical and metal, ToT simply rocks my brain. Thank you, sir.
Meanwhile, I've been a SketchUp Pro user for a few years now, mostly for simple woodworking and... lets say... architecture/construction in the form of a very complicated post and beam barn (to be built in 2019). I have come to like and effectively use SketchUp, but have always wished it had true parametric capabilities.
I recently joined the Ann Arbor Maker-Works maker space -- a wonderful non-profit w/ great people, a big heart and precious goals, www.maker-works.com/ -- and have installed Fusion 360 on my machine so I can export usable files for the Maker-Works tools. You seem to like, even promote F360, so I am now even more motivated to learn this software
I supposes one question is: can Fusion 360 be used to create a similarly parametric Master Model in the same way as Solid Works? (You may have already answered this in the video. I'll re-watch, of course...)
Thank you, Mr T !!
I'm amazed (and very dissapointed) they don't show you this "parametric" thing in University. It is so powerful. Thank you!
Great video; you obviously put a lot of work on the video content and editing. I liked the easy way you got across the idea of direct vs. parametric modeling. Thanks!
"Fun with electricity" A Frederick Collins 1936. My father had it when he was a boy, and gave it to me when I was 10. He also gave me a wooden Ford spark coil that I ran with my Marx train transformer. At least a decade later I would be hired by companies to draw schematics and then go to the lab and make them work by correcting the schematics with red ink.
...Wooden box Ford spark coil....great for running a Tesla coil...
I remember that one! My elementary school was built in the early 50's so that was practically cutting edge, even though I read it in the early 90's heh
That's a great one
I have been using 3D CAD for years. I must have seen this master modeling technique before, but cant remember it explained so clearly as here. Will definitely use it my next project. Thanks.
you're on a roll! Engineers Notebook and others by Forrest M Mims III from Radio Shack got me started. 40 plus years later and I still refer back to them from time to time.
You are truly an inspiration! Thank you so much for sharing everything and teaching us how it’s done in a very grateful way. Cheers!

I change the dimensions of my CAD models by adding or subtracting layers of cardboard.
Thanks for this video, Tony! I learned enough here to understand that I will never have the patience to learn all that. Ever. And that's valuable information :)
Very confused about the reupload, but I guess it's just impossible to expect another one already. Awesome project!
Tony,
I have a couple of thoughts on your discussion of old "technology" books. My favorite when I was a kid (a looong time ago) was "The Boy Mechanic", a publication of Popular Mechanics and Simon and Schuster. It has about 500 projects of every kind. I remember building some of the electric motors and getting ideas for a lot of kites. I still have the book. My copy has copyright dates from 1913 to 1952. They do have your electromagnet lock in there, but applied to a door rather than a drawer.
I made a carbon arc like you discussed. I can't remember where I got the idea, but my electrodes were the carbon center rods from used D size carbon zinc batteries that I tore apart. My source said that you needed a load resistor in series. I used my mom's electric iron for the load and when she saw how bright the light was she locked it away. Rats!
Paul -- max runout on youtube
Hey Tony, I know this video is 2 years old and you probably figured it out already but if you want to machine chamfers that are modeled into the part, just select the top edge of the chamfer, set the width to 0, and give it a tip offset. I don't know if you need to do this step but under the heights tab, I set both the top and bottom height to the "selected contour" option. I believe this will give you a warning but it doesn't mean anything. Hope this helps!
First of all, great video, as usual!
10:53 You would be surprised! As much as I am when I propose a parametric CAD as a design solution and am told that the parametric workflow is slower and less efficient.
I can almost feel static electricity in my head from my brain trying to compute the audio input...
Bottom line is, there is every flavour of CAD out there and people like what they are used to. (Me included, I guess)
Years of SolidWorks and a CSWA certification and I never even thought to use a master model in the way you did. I don’t know why but that just never occurred to me and I would always tediously jump between files taking measurements. This made it click for me!
MORE ON CAD.!! You are the man Tony. simply brilliant
Hey Tony!
I've been modeling things and designing parts, tools, moulds, machines with Solidworks for a couple of years now and this was the first I've seen a CAD-flow like that. I really like the idea, very straightforward and seems to work great. Sometimes in situations like you had with this part I've just started modeling an assembly. Basically draw my first main part, like the valve body and then start new part for each and every part and just model it directly on to the first part. That way I get parts parametric to each other, but there is some things it doesn't like and doesn't do and warns about doing. So definately not the best way, but works for small assemblies such as this valve :)
The Fusion360 looks nice, but I still would go with SolidCAM as it works inside Solidworks and the iMachining in it Just.Blows.Your.Mind. Watching a clapped out old crap small mill just chooch stainless without messing around with any feeds & speeds calcs or figuring out the values is priceless (well, SolidCAM has a price, 5-ish-k and up). But literally, you just tell it what you want to machine, select the material, select your tool diameter/length and tell the helix angle (not necessary, but helps in chatter calculations/warnings) and hit OK and you have an adaptive tool path with constant chip load no matter what. Want to go easier/heavier? Just use an 8-point slider to select a new level of aggressiveness (is that a word?) and hit OK.
Ah, long babling but anyways, thanks for thhe video, can't subscribe as I've already done that, so take care! :)
With cold and snowy greetings from Finland, Jaakko
Hi Tony, Enjoy all your videos. Your fun to watch!!! love the knuckle dragging design of the air gun, I want one. Thanks for your time and knowledge on the cad,it's way over my head but your helping me to figure out what cad programs to look for. M.K.S.
Thanks for watching Kelly!
0:17 Are you kidding? We're here for the small talk, joke's (dad joke's), machining, metal cutting, fab, welding, repairs, etc.
I'm not putting any of the other UA-camrs down or anything, buy if I can't find anything to watch. I'll always go to ToT n rewatch your videos as they make me happy and relaxed. I'd say it's similar when watching TV. You look through the guild/listing n there's never anything new or interesting on. The only thing that is worth watching is a film you like because it's easy relaxing watching. And it's probably a BTTF, which everyone loves 😍
If you were wondering like me, at around 9:55, what he types in is SUBSCRIBE
Pretty sure he spelled it wrong in the original upload. Couldnt have that!
Alexander Ghostly AKA Ghost8909 lol I was !
Thanks man that was a great solid works primer. Just wanted to say that although I loved the sandpaper app, I loved the pattern you sanded away more and saw it as quite texturally awesome to this graphic designers eye.
Good luck with that. I recall several books I actually owned, Science Experiments for Boys was one, and that also had projects ike arc lights from charcoal, Whimhurst machines from old 78 records and a hearth brush and the like. I'd love it now (I'd really be able to do some damage these days!) but though my mother denies throwing it out while I was out 'living my own life', I can't find it in my hundreds of books in storage and cannot even find reference to it anywhere online. Perhaps it was withdrawn by the authorities as too many kids overthrew regimes with it, but I'd love to have it again. Then again, perhaps my memory is screwed up, but seeing this video brought those longings back to front and centre. Thanks TOT.
I am a rank amateur at the simple CAD system I use, loved watching this process on your channel.
This has been very helpful with my 3d printing projects and tooling at work! Thank you!
It warms my heart to know that there exist engineers who can physically create what they have envisioned.... this isn’t common.
Simply amazing. I want to know more about SW now because of this video
Re-upload, re-comment.
Awesome CAD work and thanks for showing some of the mental process on this build was fun to watch.
I found an article on building a similar device in an archived magazine from the 1930s and gave it a try. It works, but I'd recommend using carbon rods from a lantern battery instead of pencil lead.
Forgiven, it's actually so good, it's worth a re-watch, so no harm done ;)
Haaha!! I absolutely love these videos. You are the man. I laugh out loud, and sometimes my ass off almost every video. Like the screen shot at 6:17. Keep it up man, awesome, awesome content. Never stop
new viewer here... By the way ToT... make your videos long! I want the longs ones. I love em!
I am pretty new to watching UA-cam videos . This guy is a boss!! It feels like watching something on PBS ... good brain food!!!
This video was incredibly useful. Thanks a lot, Tony!!
More tutorials is great. Wonderful videos Tony! I'd like to know more about cad software and getting started.
I did something similar in 5th grade. We were doing experiments with batteries and small light bulbs. Then the teach dozed off at his desk. I started hooking up D batteries in series with electrical tap and running the current through mechanical pencil lead. It would proceed to heat up, glow, and melt through the plastic chairs. Not quite the full arc furnace, but just as fun.
Tony!
Great video! Fantastic explanation on Master Modeling. I wish some of the large Fortune 500 companies I do design work for grasped and applied this principle.
At 6:16 ... Tony you have to strip the ends of the wire to insure good continuity, especially in a high current circuit like this one. Awesome design from a reliability standpoint.
Fantastic description of Design Intent, to setup for later, quite informative.
Keen to try out you master sketch method as I haven’t done a lot of true parametric modelling. I have been mucking around with Solidworks for a little while now. I have the 2014 version, and really like it. Thanks for the video 👍🏼😎
Phew! Thought this vanished into thin air... I only watched the first half yesterday and couldn't find it this AM. Relief.
My first introduction was a box of wires, switches, motors and light bulbs that, at twelve volts, not suseptable to blowout from the 4.5 volt batteries I was given.
Next level was a Tandy experiment board, with lots of parts on a cardboard base with connection possible using springs.
Next stage was an apprenticeship and 4 years of college. 😊
I would enjoy watching more videos of cad by you! You make it much more palatable! That says a lot for someone with my attention span! Squirrel!!!
Still Brilliantly executed Edutainment TOTony and I was smarter this time not to abnormally aspirate my coffee while watching for the third time. The mix of design elements and design operations worked perfectly with your excellent cinematography. A nice dance with the music and the 4 up milling sequence! With the advent of CAD and Parametric modeling the old saying I was taught "Never draw more in the morning than you can erase in the afternoon" is heading for extinction I think...and now with CAM/3D Print it seems like Fusion360 is a step closer to a unified field theory were we might project our mind to create out of thin Ethers. I remember writing LISP with nut and bolt spreadsheet info and BOM output for ASSY's and it seemed like magic at the time...endless possibilities.
The books I remember were Popular Science and Mechanics having sections for kid experiments back in the late 50' and 60's. The "Lady Bird Books" below looks pretty good though. Also the Forrest Mimms books were great for teaching my son basic electronics.
This is a great format and hope you continue with more of these!! Big O' Thank You TOTony, well done to say the least! ~PJ
what a great saying!
No officer, these aren't brass knuckles, it's just an air gun. See the valve?!
You used the word 'gun' - off to jail with you...
Me: No officer, it might have "Cali Commie AR 15 of doom" engraved on it, but it is an air blower.
Cop: AR... ASSAULT AIR BLOWER! YOU ARE UNDER ARREST. You have the right to remain silent... .
sadly, that is the mentality of most people today... even on ebay if you try to list say a glue "gun", or a toy "gun", heat gun, soldering gun, ect ect ect.... it always gets flagged under their "vero" items simply because it contains the word "gun"....
for many reasons, it is truly a sad and willfully stupid generation in which we live...

During your final rendered motion animation, it looked like you had some handle to frame interference just behind the valve head in the area of the body radius and handle underside. Not a big deal. I would also say you may be looking at some soft tissue impingement ( pinching of skin on your hand) between the handle and body. A larger radius on the underside of the handle may solve that. You also did a masterful job of hiding the side to side profile mismatch during filming. Once you generated the holes and sculpted the body, you could have used buttons in those holes to secure the part to a plate for a full perimeter cut and not worried about a parting line remnant or mismatch. I do scuba light trays like this all the time and the technique is sound. Oh yea...one more thing...you forgot to engrave Diresta in 47 places on the body. As always, thumbs up.
Thanks Joe! The rendering wasn't the final CAD, I didn't get any pinching, and good tip on the buttons! I usually use the router to drill dowel holes for this kind of work, straight down into the fixture plate.
Whenever I am looking at a job like that, If I have a choice, I would rather put the potential mismatch on the chamfers than a profile surface. They can be out and its practically invisible. Thanks for the reply. Keep up the great videos. I always enjoy your projects.
Another great video Mr TOT, thank you.
The Dangerous book for boys is my go to gift for all my friends' kids' birthdays when they reach 9 or 10. My sons both got the book at 10 as well. I highly recommend it.
Future parts and Polaroids, Priceless.
you could make the vent hole through the valve either all way through to the top or possibly to the output side
I was thinking the same thing. But it wouldn't be a good pressure regulator anymore. Just on and off.
Thank you so much for this video. It is going to help so much with my solidworks design work for my degree so much. I only wish I learned this "master" concept before pouring way too much time into my design projects.
Amazing content. After AutoCad and Inventor, Solidworks in next in the schedule.. Looking forward to it and hope to see some more SW stuff from you. Thanks Tony!
I hope that you will do more CAD side of your project .keep up the good information
Popular Mechanics Encyclopedia from the 50's or 60's. It has all kinds of dangerous DIY projects and mods for stuff.
My favorite childhood experiment was in 5th grade when we made dry ice artillery... later that week I started going into pressure vessels, leading me down a rabbit hole of various rocket motors, leading to aerodynamics, leading to full out amateur liquid fueled rocketry (thank you local rocket club)... later I moved to Indiana and am no longer able to do liquid fuel... so I now terrorize kerbals
I loved Popular Mechanics magazine when I was a kid. I actually had my own subscription :-) Lots of good info in those magazines though... at least there used to be... but like nearly everything else today, its probably been bought out by liberals and they probably only have "cup cake recipes" or "makeup advice for "boys"" or whatever in it now....
it is a sad sad thing to see just how far the last few generations have fallen, let alone the current generation... real men are getting fewer and fewer every day.
"Dangerous" is the chemistry books from the 30 and 40's. Some UA-camr has a few videos on replicating those formularies. He found the book in the school's garbage Dumpster.
@@Yhrim70 real men? Seems your totally full of male toxicity. I know two women who were doing those electronic projects from popular mechanics back then. One of those women was my mother. She was not afraid to try experiments with me. So bugger off with your "real men" statement.
@@troyna77 Very cunning, to play the "you are probably full of toxic masculinity, so shut up" card. Well, nothing prevents women from doing "boys things", should they choose to, except maybe overprotective parents. Stating that boys are no longer allowed/motivated to do "boys things" is nothing toxic.
But all that is irrelevant, because you know exactly who is full of toxicity and therefore their opinion is no longer valid, right? I am Soooo glad to have you around...
No, seriously, think of a better counter, see if you find one.
i used to have the exact book you describe. i can't be 100% sure but i'm almost certain it was written by alfred morgan (wikipedia lists him as alfred powell morgan) and i'm pretty sure it was called 'a first electrical book for boys'. i could be wrong on the title because morgan was somewhat prolific and some of his books had similar titles, and other books were republished with different titles.
another of the projects i remember from that book was the jacob's ladder made from a model t spark coil. just in case a model t spark coil might not be available, he included detailed instructions on how to build one from scratch.
thank you for the great explanation about parsmetrics
Superb presentation. I am too much of an old dog for this, though I use the minimal of plain CAD. As I see it the third O ring stops the air pressure helping the spring. Beyond this nice decorative piece, why would I use an air blower which is more difficult to pick up than any other? ????
