I like how you go into more detail on the machining operations than most of the machining youtubers. also, you're forgiven for the end mill.
Yeah after watching a lot of other UA-camrs, i forget that sometimes everything just goes to plan.
"Forgiven" for the end mill? Why? End mill with "PLUNGE" is nothing "new". Been around for MANY decades. How do you think machining a pocket is done?
Your narrative and explanation of minute details are INSANE !!! GREAT.
I think this is one of the best produced machining videos I have ever seen.
GOD BLESS YOU ADAM. LONG TIME NOT SEEING YOU. I REALLY APPRECIATE YOUR TEACHINGS AND LOUIS. I AN STILL IMPRESSED FOR YOUR GREAT CAPACITY FOR TEACHING AND PERFORMANCE AT THE SHOP. YOU ARE VERY INTELLIGENT AND VERY INSPIRATIONAL!!!
Wow. The amount of work put into illustrating every part makes this fairly complicated build very easy to follow.
I'll probably never make an air bearing but your teaching is so good I feel like I could.
I'm no dentist yet this video has helped clarify a few things. Ty.
I stumbled on your channel about a month ago and spent a night watching them all and marveling at your explanations and production value. I got to the end and was seriously bummed out to see your last video was a year ago. Then out of nowhere you post two great videos only two weeks apart! What a great surprise and a valuable insight into industrial tech! Thanks and keep them coming !
Dude! I'll just go back to sweeping up shavings, humbled by your god level explanatory nerding and workshoppery. Thanks for sharing ;)
Just found this channel,
Applied science, Steves POV and this all in one day, I'm on a roll
I very much appreciate your step-by-step explanations of machining processes. I'm just getting into simple, hand tool hobby shaping of aluminum and it's nice to see the approach and thought process.
I like this series. Good job on explaining the different techniques and tools you're using.
I'm 4 minutes into this video and had to pause ... to put my noise-cancelling headphones on, settle into my seat so I can give it my full attention, hit "Like", subscribe and write this comment. This has amazing educational and production value.
I'm very much looking forward to the next video! Great idea about using the arbour press to force the aluminium into a conformant shape with the ball bearing.
As much as I cringed for the end mill misuse, your display of knowledge and understanding more than makes up for that. No broken end mills!
This content is so well made.. thank you!
Your explanations are so clear and detailed. Presentation is very well done. The same type of accuracy we had to do in our school making machining project reports, those were pretty useless, but in this aplication of making instructional videos it just works. Good job!
the effort you put into clearly explaining and animating everything is more than most youtubers and even some production studios..
this is now one if my top 5 favorite channels(out of a couple hundred subs).
looking forward to the next vid.
Thank you for making this video!
It was EXACTLY what I needed to see before my next project.
Thank you for the details about each operation. I like it a lot!
Very cool, good to see you back!
I'm a professional engineer...and I learned so much from this video. Great job!
amazing content and production. thanks for putting in all the work to make this video. it shows.
Sick vijeo! Im super excited to see the lathe!!
Awesome work! Thanks for shearing!
Love the detail and explanations. Subscribed!
Awesome narration! Best out there!
Fantastic story arc, videography, presentation and editing... and a great subject that has got me hooked. Thank you for making these videos!
I can well imagine you round about 2068 doing a YT channel in the style of mrpete, who knows what challenges and solutions you'll have taught by then!
Incredible amount of detail! Very informative and entertaining at the same time ... much better than any of my engineering Professors!
Excellent!
ATB, Robin
Your videos are so well made and provide fantastic information. I can't wait for the next one!
Can't wait for the next episode!
Loveley video, can't wait for more
you present very well.. Good technology.
I’m really excited for the micron machine you’re going to build
I have no words but well done 🙂👍
As others have noted, the presentation and content are exceptional. I always enjoy your instructional videos. I can't wait for the next one.
Miss Yojimbo, though. :-)
An utterly incredible video! Seriously informative!
Thanks, Alec! Very much appreciated.
Wow this is awesome information. The machine shop I work at has a sinker ENM. We have a mountain of used graphite from different electrodes we've made over time for making injection molds. I've been looking for a cool project to do with it. I'm definitely going to give this a try. I really like anything that involves anodizing aluminum. I have an addiction to anodizing. Thanks!
I thought you died, I’m glad you’re back. Take as much time as you need
learned something??? I learned A lot !! Awesome video Adam👍👍
Thanks!
This guy Adam is awesome.
We used to machine graphite all the time. Thank God we do not do that now. The hands were always shiny black tinge. Very well explained video fella.
Im sad it ended
Victor Hugo same 😅
This insight into end mills for flat bottomed roughing would have been super useful about 14 hours before I saw this video. It would have saved me a DICKLOAD of broken dreams at trade School this afternoon. But thanks, now I know my problem was the reverse of what I thought it was, and I shan't do it again!
I learned a lot, I just wish if I have a workshop like yours
Detailed, but good pacing so it’s fun rather than plodding. Props.
High quality! Thank.you.
my God! He's back!
Great vid. One quibble, and it's not a biggie: A lot of newbies, (and American newbies more than most) have a tendency to assume that they can compensate for lack of experience by putting more emphasis (and money) into the technology. While this is true to a degree, it can be a distraction, and an expensive one.
Specifically: Using solid carbide boring bars, spotting drills and suchlike is a useful dodge in a tight corner (like spot-drilling ultra hard materials, or in the case of the boring bar, a hole which is very deep in relation to diameter) but when a home shop is making a part from alu alloy it usually has no measurable payoff, and there's always a tradeoff because solid carbide is stiff but fragile, and a klutzy tyro can waste hundreds of dollars of tooling in an instant, simply by omitting to check from several angles before moving the carriage or spinning a toolholder.
Carbide endmills can be great in alu if it's gummy, or if you need a superb finish by side milling a flat face, but you need to know what you're doing with feeds, speeds, sharpness and coolant.
And for the superb finish, the machine's spindle and ways need to be in decent shape. If some or all of these are not true (and of course this is just one opinion) you're better off with HSS, and spend the money saved on tooling to keep a bigger range, and keep it dead sharp. (An ounce of sharpness is worth a pound of almost anything else)
Just found your videos. Thanks! Subbed!
can't wait to see the cylindrical air bearing video (I'm thinking of making a crankshaft precision balancing setup): have to come up with a trick to get the proper ID fit in carbon, hopefully without damaging the journal surface of the part to be balanced...
dude i love the intro music
Awesome!
This motivates me
awesome!
Very well done, would like to see a video about hydrostatic bearings. like what kern cnc machines use
Great job with good explanation . In need the same thing for a tesla turbine because the shaft run with a very high speed
You got a patreon boss? Game changing content here, love to see it
You are awesome really
The triangle seat would be best partially roughed and then pressed in before machining, then mounted between centers to make sure the point of the triangle is on center. This would also strain harden the material creating a better wear surface for the ball bearing.
Fantastic tutorial, I like the very detailed breakdown of the operations.
-> Is the carbide vs steel shank on the boring bar important? Perhaps it’s stiffer?
God tier!
you are a maestro
Hey, awesome Video in incredible quality! Keep up the good work! When you're going to anodize the casing in the future, please explain this process in great detail and how it can be done at home with the minimum amount of tools! I would really like to do anodizing at home, but i don't really know what tools i need and if it's worth the money to get them.
In the next video, I will demonstrate a simple, relatively inexpensive way to anodize aluminum parts and I will definitely explain the process. It's not controlled or consistent enough for professional metal finishing operations, but it's quick and easy for one-off parts in a small shop. I should say that this is a well-covered topic and there are a lot of great videos on youtube already. For example, ua-cam.com/video/P8oesBi7_II/v-deo.html
What type of Graphite grade insert you are using and the type of epoxy to glue, I really enjoy the video. Thank You
13:08 great tip/trick, thanks
great informative video! On a separate note i'd recommend you buy a polarizer filter for your lens to remove glare from your glasses. Works like a charm!
Ooh, good idea!
gotta love the scorn x'D
Cryogenic stress relief is a thing.
You got too love that.🤜🏼🤛🏼🇦🇺🍀😎🤓
Can you tell me what kind of graphite material this is? Is it ordinary graphite that can be used for high-temperature molds? I wonder what kind of process is used to ensure the porosity of the porous? Thanks for your answer
Is it possible to build a super precise lathe with these bearings?
To mitigate dust release, could you have not kept the graphite rod in some oil bottle (I'm thinking 3-in-1) for a while, so that it seeps into the pores and binds the dust?
Clever intro
Why couldn't you have lapped the bearing into the aluminium, then you would have had more of a socket/pocket for more depth? Fantastic video and lovely work shop and tooling detail!!
Gosh, that sounds like a lot of work. The pressed-in spherical annulus is super easy, quick and cheap to make and it works better than pretty much anything else for precision ball mounts. To get better performance, you'd have to move to a flexure design.
Nice video. 1 question.
What is your 3 jaw chuck brand. I love to have capability to use aluminium soft jaw
It's made by Bison.
@@LaneyMachineTech thanks
Would 0.02-1mm resin prints make this work... ?
Kindly upload any overhauling video of pump and compressor...... Thanks in advance
For the ball you can put it in a drill chuck and a little lapping compound would be more accurate
I can't believe you put an end mill in a drill chuck. The run out. Do you also use your calipers to scribe lines? LOL
Will you be doing something similar for cylindrical bearings? Regards, Matthew.
I had planned only on making videos for flat bearings (for granite guideways) and spherical bearings (for machine tool spindle). But now I'm contemplating making videos on radial bearings and orifice-type flat bearings. It depends on my availability and the interest out in UA-camLand.
@@LaneyMachineTech Count me as interested. :-)
@@LaneyMachineTech Count me in as well
Do you know what CFM you need per bearing? or CMM for metric?
As I'll show in a later video, that's a slightly complex question, but it works out to about 1 SCFH (0.02 CFM). It's very low.
The cliffhanger!!!
Could you press fit 3 hardened dowel pins into the top to provide 3 hardened contact points for the ball?
Yup, good idea. I've been thinking a lot about kinematic joints and couplings recently, and I think I may do a video demonstrating some of the great solutions people have mentioned in the comments. I also thought of a "simple" way to generate a trihedral which I'd like to share.
Machine Tech Video Blog looking forward to it 👍🏼
hope I can buy these air bearing modules... many of us (actually most of us) don't have a lathe...
Is the tool blank pre-hardened?
Yes, and they usually are. FYI I was using REX AAA, a T4 grade of high speed steel which is a decent and very inexpensive general purpose tool material.
is a hovercraft an air bearing?
In this video series, you keep referring to the videos by their Part number ("Go back and watch Part 1..."), but you did not include Part number identifiers in the titles. Could you refer to the videos by their titles, or better, add Part numbers to the titles of multi-part videos. Thank you, and love your work.
12:40 why not use the indent from the Ball?
where is part 3? have I missed something
God praise Mechanical Engineering ❤️
David well guess what machining is a part of manufacturing and manufacturing is a branch of a mechanical engineering 😏
There is nothing hacky or otherwise shameful about drilling a flat bottom hole with an end mill. It's perfectly acceptable practice. Trust me, it's done in industry all the time.
very nice video, outstanding quality, but dude pls make that music at the start of it a little quieter. Like, 35% quieter)))
I will be waiting for you, I,ll be back, hasta la vista baby.
99% of the world want's to thank you, for putting all the metric values. Videos with fractions and imperial units are just hard to watch and understand.
AAAAAAAAAGH, you got your HSS tool blank so hot it went blue! that alters its heat treatment properties.
A detail: increasing material hardness does not increase stiffness.
If you really wanted a simple three face cut then a rotary broach might do it with a cut bottom face to a point??????
I had not considered using a rotary broach (probably because I don't have access to one), but that's an intriguing idea. Machining a trihedron is a pretty good little challenge!
Where is part 3
Couldn't you broach the triangle?
