Is it me, or was the block used for the keys 1 half of the press jig that Quinn made for the captive springs for her toolmakers clamps?
Whoa, good eye. That’s a real fan. 😁
@@Blondihacks You clearly have a 3D printer but I couldn't find any vids on it.
If you get bored one day wanna tell us what you have, why you got that particular unit, what's good about it, what could be better, what you might get if you were going to buy another one. A few YT machinists have them but few tell us much if anything about the ones they have.
@@tonywilson4713 I have 2 printers myself and have done a lot of research in the last few months for a friend who wanted to buy one. I came to the conclusion that if you want it to work great out of the box, get a Prusa i3 Mk3. If you want to save a lot of money and still have a great first 3d printer, get an Ender 3 V2.
The Prusas apparently really are amazing, and the Ender 3's are great and a *ton* of hobbyists own them, so they're really easy to fix or upgrade.
Unfortunately, I own neither of those. I have 2 TronXY printers, 1 that I loved (it's basically an ender 3 clone and I'm in the middle of upgrading it) and 1 that I've had nothing but problems with and wouldn't wish on an enemy.
@@Raytenecks Thanks.
What do you use yours for? I suspect that makes a huge difference. I have seen units with exchangeable heads and can do 3D printing, light CNC milling and laser work. There's whole channels dedicated to the stuff and its easy to get lost.
What I am interested in is what units machinist people have gotten and why they got them.
Stefan Gotteswinter has 2 small CNC mills and has covered both and explained why he got the specific machines he got.
@@tonywilson4713 I'm not a machinist, I just find this channel fascinating.
I used my 3d printer to make a 3d printed CNC router (actually, working on the upgrade for that, and it'll also be my upgrade for my laser cnc) and some jigs for woodworking, as well as little holders and things around the house. It's also useful for upgrading the printers themselves.
I truly appreciate you showing us the technique to get asymmetrical radii. None of the other machining channels ever think that their audience is capable of understanding such advanced techniques.
Excellent, as always. I'm reminded of the time that my wife asked me: "What do you need a mill for?" And I said that it would be handy to make accessories for my lathe. "So, why do you need a lathe, then?" She asked. "Obviously: to make accessories for the mill." I said.
And now I know what the gaps on the underside of my rotary table are for. That's a *big* help.
I appreciate you making the T-slot tabs out of a small scrap. I'm often amazed how UA-cam machinists do things like make a temporary fixture using some $200 gigantic piece of really high quality material for no reason. There are a lot of things people make that aren't at all worth the raw materials they used to make it.
Perhaps true, but it is surprising what one can salvage from junked equipment and "gigantic" is very subjective
I routinely make the pockets in my 3D prints a little deeper than the magnets. I tell my slicer that I plan to change filament, pausing the printer so that I can drop the magnet into the pocket and then usually print 2 layers over the magnet. This gives me embedded (and hidden) catches. That lets me skip the tappy-tap-tap and glue, as well as ensuring that the magnets will never work free.
In Prusa Slicer and other slicer as well, you can add pauses specifically for inserting things like this. I've done the same with nuts and have seen steel cable inserted to strength prints.
@@ADBBuild Yeah, I was gonna say, very useful for nuts. There's also a trick I saw on hackaday a while back for doing floating holes, where you model in some material for bridging the thickness of one layer height. Title of the hackaday article was "Look Ma, No Support For My Floating Holes!" if you want to go check it out.
The nails as hinges is such a good idea too
@@auxchar I do this all the time with counterbores that are upside down. Works great!
i'm running an Ender3 printer and am curious if the magnet ever took flight and stuck to something steel on the printhead before the magnet was entombed ?
A well rounded demonstration of a good way to cut corners. Hopefully someday I’ll also get around to it. I also keyed both my mill vise and a tilting table that I have to change out frequently and it takes a lot of the tedium out of constantly having to tram everything all of the time.
Oh, I thought you meant something else with "cut corners".... ;)
Keying my vise and rotary table are now on my list to do!
A newbie here & you older hands may have already known this, but was blown away by the simple expedient of a scrap copper wire in the vise for unknown squareness of stock.
No biggie for you, but ingenious to me. Thanks, Quinn! You teach more than you think you do.
As someone just getting their start entering a world of more precision, I really appreciate the time you take to make these videos. Even if the main topic isn't relatable to my own work, the individual techniques you show during the process are an absolute wealth of education. Thank you!
As a retired elder who spent some years of my education and career in industrial arts, mechanical engineering, and manufacturing, I very well recognize that you have an astoundingly good understanding of the many fundamental tools, practices, techniques, and methods of industrial machining and related materials and crafts. Since the teaching of "industrial arts" in public schools has now been entirely abandoned almost everywhere (I suppose for "liability reasons"), I often wonder where you have learned it so well without actually being previously trained and employed as a professional machinist. (Perhaps you actually were, and I'm just ignorant of that fact.) As you well know, you are a very unique person for your age in this respect. I admire and respect your abilities, knowledge, energy, ambition, cleverness, persistence, and resolve. Your willingness and courage to extend your knowledge and challenge yourself with difficult projects is truly wonderful. You have a natural talent for teaching these topics too, along with a great sense of humor, and you should be commended for sharing your knowledge and experience so freely. Best wishes to you!
Very well said Antti. My feelings, exactly!
G’day mate,
Caught your comment about industrial arts disappearing from schools……….I’ll make some assumptions here……….
The cost of setting up specialist rooms for teaching hands on skills were astronomical. Most of the rooms would have $50,000 of gear in them.
Most of the gear is dangerous so the rooms can only be used for specialist instruction, you can’t take a French class into a woodwork room without some risk. Imagine a young teacher in a woodwork room for a double period of History, for two periods after lunch on a Thursday………..disaster!!!
The other problem is that the majority of specialist teachers in these courses were recruited from the ranks of artisans, recruited from industry in the early days and many returned servicemen. We can’t go back to the 1970s when boys did woodwork, metalwork and Technical drawing, while the girls did cooking’ and sewin’.
Sad as it seems that’s the way it was!!

That is why Darwin's theory exists.
The idiots remove themselves from the gene pool... or at least learn sense from the shaving off of smaller pieces.
Nice job, especially the little storage box. Thanks for the promo too.
You are very generous with your time and very good at this. I have the Harbor Freight red lathe and its matching mill that I have completely disassembeled for cleaning the thick shipment grease. Reconstitution is my next step. Your work, even though it is on much nicer tools, lends itself beautifully to my cheaper tools. Thank you for it. You are an exquisite instructor. //John in Oregon
Ah the first of many disassemblementifications. I've taken my lil red apart probably 10 times. It now cuts awesome. But Holy cats lets just say i know all its inner working.
I literally clapped and yelled yay when you closed the box, tyvm
My shop is in the basement of my home and to make a long story less long, I passed up a chance at an old Southbend lathe and Bridgeport mill for $2000 (yeah, I cried for three days) because of space limitations and absolutely no way to get them in. So, I've been working on a Precision Matthews 1228VF-LB lathe and I'm considering purchasing a PM-25MV mill. Your space situation is similar to mine and these videos have been a great source of inspiration for my small shop addiction. I'm finding that with a little ingenuity you can make some fairly precise parts with some of the import stuff. I've had good luck with the PM lathe.
Brilliant design of this fixture, BTW. When I finally get a mill in here I think it will be one of my first projects - after getting the vice, rotary table, tooling, etc. of course, and a partridge in a pear tree.
...wait... no pre-intro?! Sounds like everything went right! 👍💪👏👏👏 Watching now to find out... *drum roll*
...and what an ending! A 3d printed box to put it all in?! 💪👏👏👏👏👏
Great project! I'm going to consider this a straight-up homework assignment. (No more please). Thanks
Nice call on Presling's channel. Something for everybody over there. Or down there, if you will.
Neat little tool. Just add a short 125 parallel into the storage area and its all in one box !
Good idea!
Another great project from Blondie Hacks, who it is nice to know that you make silly mistakes like the rest of us. Doesn't affect your 'Machining God' status on the UA-cam. Thanks very much.
Anyone else find themselves saying “Tappy-tap-tap” to complete strangers? Make a T-Shirt of that Quinn!
I recently identified a like-minded individual when they uttered that great new code phrase....translates to Quinn Rocks!
Quinn, I'm sure glad you made this video. I have a lot of corner rounding to do on my locomotive project. I had been thinking along similar lines, But you really put the period at the end of the sentence. Thank you.
I am bedazzled by your work. I have always dreamed of being a machineist; even if only as a hobby of small work pieces. Your videos and library are awesome. ⭐ ⭐ ⭐ ⭐ ⭐
Pure artwork in motion!
Nicely printed box 👍For hinge pins, you can also use a little piece of 1.75mm 3D printer filament of the spool. Works great!
So darned cool, Quinn; especially liked the icing of the 3D-printed storage box and magnetic closure. Outstanding.
The flat spot on the 'dogbone' is deliberate for easy drill centering for a setscrew! 🤔🙄😏😉😁😎
You understand! 😬
@@Blondihacks it's not a mistake, it's an undocumented feature.
I love your channel because of videos like this one. You "birth to grave" the entire problem and explain and show every step, explaining not only what you are doing but why with great finesse.
I encountered a similar problem not long ago on our 10 and 12 inch Vertex.
I had to give up and as the grey haired ones for help: they determined the taper and I was able to turn some Delrin index pins (I didn't need them to withstand milling forces, just to index parts concentric on varying sized bores for repair).
As always I've come away from one of your videos for new ideas to try out at the shop.
Cheers!
Like it….simple/smart, making shop items/tooling is great
Another fine video teaching the unteachable how to use their tools/machines, using a let's figure this out together type approach.! I enjoy all your vids. Only complaint is, every time I watch one of your videos, I end up spending $100 or so buying tools...LOL. Thank you for teaching us, Quinn.
The 3D printed box was the icing on a delicious cake 😋 Another brilliant episode. Thank you 👏👏👍😀
Making your own tools is one thing, but making the tools and then a handy little storage box for them ... that's incredibly satisfying :D
Woah! Perfect timing! I have just started a project that will desperately need one of these to cut the manufacturing time down.
Your attention to detail, commentary and visuals are a true testament to the quality of the products you turn out. Extremely satisifying
Nice! I wish that videos like this had been available 30 years age when I was learning.
Your technique of using the rotary table to flatten the taper in the mill was mind blowing!
I made a bar that fits into the t slot for radiusing by hand without having to wind that worm gear round and round on multiple parts.
Snazzy indded. Nice job on both the inserts and their case.
Beautiful, and I love the storage box.
Great use of resources making a 3D print for your fixture.
I used to work those machines a bit for a living when I was a youngster. My life took a different turn and I ended up doing completely different things. I really miss machining and watching you have all the fun helps🤣🤣. I like your work. Enjoy watching your channel.
I don't know what you do when you're not making awesome videos, but you would be an excellent teacher. Great video, good information. Thankyou.
this is the first video of yours that i have viewed, you are quite the machinist / videographer ! thank you
As always, very nicely done.
I laughed, I cried, I ...
Nevermind.
Thanks, and Meow to Sprocket.
Brilliant - exactly what I was after. Thank you 😊
Tremendous! And the timing couldn't be better. Thank you, Mighty Quinn! 😀
So lovely how you deepdive into whatever topic, love the 3D printing as an extra tool in the shop as well!
Some brilliant techniques there. I love the storage box at the end too
That was a great video. Thanks. I love how it was completed down the the storage case.
This is yet another case where you're solving problems in a much cleverer way than I managed a few weeks ago.
Same sort of mill, same sort of lathe, same sort of rotary table, very similar problems.
Thank you so much.
Love your videos. Very informative, and well presented. Thanks, Mike
WOW !! I can't believe you nailed that bullseye dead on 👍👍 🤣🤣
😬
Very nice fixture. Thanks for posting.
Im a toolmaker and i freakin love this channel
Very, very cool. Thanks B.H. !
Keep it up!
Fantastic video! Been watching for a long time, and this i think may be the best. I love building tooling more than actually making the projects.
Very cool. Yet another project to put on the list for when I built my shop.
That was an absolute pleasure to watch
Rewatching this to get some ideas for an MT arbor to turn thin discs on a lathe with a variety of center holes.
Fantastic , loved the 3d printed parts box at the end . Good job .
Thumbs up and subbed 😊
Really nice work. I have been wanting to make a fixture like this for a while.
You are a real toolmaker!
an engineer at heart ... finding the simplest way to do the more difficult tasks ...
o7 I salute you for scrap usage in shop projects. Admirable!
I especially found the little box you took the time to design and 3D print adorable.
Simply put; well done. Thank you.
I always learn so much from your videos! Thank you!
Superb. Tutorial and relaxation therapy in one.
I am in awe of your patience.
i do this basically the exact same way, but i've got a small grinding vise (barely) clamped to the rotary table.. fairly repeatable since you're centering on the mandrel, and makes duplicate parts a bit quicker than having to deal with strap clamps!
Entertaining, and informative, as usual. Thanks, Mike
I especially liked the technique of plunging into the 2MT mandrel in order to get it to match the rotary table height exactly. Great video!
Thanks Quinn! Your timing for me is impeccable because I just started a project where I will need to round over the ends of a flat bar of stainless steel. For this I'm justifying buying a small modestly priced low profile rotary table.
Excellent job Quinn.👍👍
Another excellent instructional video, I really appreciate the deliberate mistakes to demonstrate what happens. Steve
As usual, you really didn’t cut any corners making yourself a corner cutting fixture. Great video, thank you!
Excellence project! Thanks for sharing with us. I too am prone to printing boxes for my fixturing! A nice way to wrap up a project and store a nice new tool. : )
Thanks for including the 3d printed box in the video, I've been trying to think of a good way to make a box for my cheapo dial indicator and that's a pretty elegant way to do it. Fantastic video as always!
Fantastic as usual. Enjoy your videos😊
Brilliant idea Quinn!! I'm a new machinist and I've learned so much from you....I truly appreciate it!! 🙏
Keep up the great work!! 👍👍
That was very good Quinn. I guess if you did not have that fixture you could use an m2 centre, put your part on the centre pack between that and the table. Then clamp down. The centre would give you a larger hole size variation, just have to have a selection of packing. Just a thought 😀
Adjustable parallels would be good for that setup. And if needing to take heavy cuts, it does occur to me that a more secure alternative to a Morse 2 centre with its 60deg conical tip would be a Morse 2 > Jacobs Taper (drill chuck) arbor. It would still allow for a (lesser) variation in hole diameter but would not produce the same degree of uplift as a reaction to the cutting forces.
Nice to bring the last few lessons full circle and show a practical use for positive reinforcement, thanks!
Another great video. Thank you for the effort on doing the video
Perfect. Thanks for the learning!
Brilliant video. I 3D print a lot of stuff and the nail hinge is something I am very much going to steal 🙂 Thanks
Very clever! Well done.
Nice shop build Quinn, the 3d printed box is a great way to keep all the bits.
The 3d printed box is a nice touch.
That's a very cool little project. Nice.
Thank you for another great video.
You are a very clever and informative young Lady.
Keep up the great work.
I sadly don't have a workshop, but I love watching machinist making things (I seem to be subscribed to all the channels you namedrop). I do, however, have a 3D printer, and you have inspired me this video to make some little boxes for the random collection of tools I do have!
Great job quin! Looks great!
When making keys to index vices or rotary tables on the mill table, I simply make round buttons with the appropriate dimensions in my lathe. Much easier.
That's simply brilliant.
Or maybe brilliantly simple!
For tooling I prefer blocks as keys, more contact and longer wearing. I use buttons or shoulder screws with modified heads for fixtures.
A good addition to the kit would be a puller for the mandrel. Just a inverted cup with a hole in the center. The the hold down screw extracts the mandrel and the rotary table can stay in position.
Much nicer than the one I made!
You & Preso are my Sunday morning coffee ritual.
The roundup I needed on this topic!
Cool! I'm going to have to make one of these now. Thanks for another entertaining and informative video.
Quinn, I look forward to the Saturday afternoon video's and learning new big words Ped-a-gog-i-cal adjective ( relating to teaching) and you are a great teacher !!!!!!
I laughed out loud when the 3D printed box appeared. Brilliant attention to detail. Thank You for the amazing videos you make, I'm hooked on them and can't wait for the next one to come along.
I just made one following this video. It did a lovely job for my crank webs! Tha ks again Quinn!
It sure is amazing how useful special jigs are for performing a task, you explain things so well thank you.
Nice work as always 👍
Pro tip there with using the drill chuck for quick squaring of the part back in the jaws, so obvious but easy to overlook. I won't be scared to remake the morse taper for my drill chuck on my end stock (mines been "mangled" before I bought my lathe).
