That's a great lesson, Joe. Thanks for noting all the subtleties to watch out for. There's a thin line between success and failure on an operation like this, and guidance from an experienced master makes all the difference.
Excellent job. Just demonstrates how much engineering and engineering skill is required for a simple part. Most people don't appreciate how much effort is involved.
20K worth of machinery for a .10 part.
Good technique and demonstration. Looking forward to the next part. This stuff is great!Thank you.
Thanks for watching.
Super good technique. You add a lot of high quality education to the library of TH-cam machining video instruction out there (and I have watched a lot of it). What a wonderful resource for us and future machinists! Thanks.
Thank you Jim.
"that's not a bad trick" is an understatement. thx for this tip.
Pressure is the key. Good luck.
I've used this trick quite a few times now, and I learned it right here years ago.
Thank you Joe, for so many tips that I get to use almost daily. And trust me, I remember where I learned every one of them.
Thanks. Pass it on.
I learn something new with every video you present, I am a hobby machinist who builds big astronomical telescopes, cameras and associated equipment-so machining is a means to an end. As a former medical pathology lab scientist, my natural hand skills have allowed me to design and make many of my items I have used in research projects-but self taught is not the same as being taught either the correct way or by by professional machinists. It took me nearly two years to build a Stuart Turner Vertical 10 steam engine as a first project so many years ago. Wish I had You Tube back in the 1960's.
Could you imagine where we would be now. Thanks for watching.
Wow! Just the job to deal with a problem many of us face. Thanks for taking the time to share it.
Patience is the key. Good luck.
WOW THANKS!! I'm an old guy with a beater old 10" SB, know "just enough" to make something fairly round, LOL. This was a GREAT tip and will probably give me more ideas.
I just happened across your channel a week or so ago. I have to say I'm impressed. You are a good at instructing and your videos are very informative. I work as a maintenance mechanic/welder/ machinist. I'm no where near a journeyman machinist, but I usually get done what we need. We have some electric motors that have automatic brakes and use a variety of thin spacers to maintain proper clearance. This and the boring video was very handy to watch. You have earned a subscriber and I look forward to binge watching more of your videos.
Joe... thanks for posting these incredibly educational videos. You, Adam, Stefan, Tony, both Toms, Robin, the Keith twins, Mr. Pete and many more TH-cam professors have advanced my skills and knowledge immeasurably. I watched this video when you first posted it and I'm glad it imprinted within the recesses of my mind.
Yesterday I discovered I need some very small diameter washers to salvage a project. The washers need an O.D of .658", an I.D. of .190" and thickness of .001", .002", .005" and .010". I don't know where I'd even begin to source them. I'm relieved to have remembered and revisited this video. I'm heading out to my shop right now to make the washers from my supply of shim stock. You've turned my dread and despair into excitement and elation!
Thanks again Professor Joe!

Great comment, and thank you for your support. You have inspired me to post the video on how to bore those washers once thay are done. Its a great trick and worth watching. Stay tuned.
Excellent! Thanks for sharing and the clear logic behind each step!
This video is my textbook for today. Your videos are incredibly useful for machining with manual equipment.
Ive been doing this for 35+ years and I always find new ideas that I can use in these videos.
Excellent.
One of the things that I learned long ago, was that if I teach you what I know, and you teach me what you know, we are all better off in the long run.
However, there are too many out there that are secretive of their knowledge because of fear: Fear of being replaced, fear of not being recognized as the most knowledgeable, etc. This is something that must be overcome if we are to succeed, not only in the trades, but in Life itself.
I'm always amazed at how something that should be theoretically simple (cutting a generic solid of rotation) is so complicated and multifaceted because of the complexities of reality. And I'm also always amazed every time I see one of you videos come up, because I think "wow, I haven't needed to do that yet, but damn I don't know how so I better check it out." Because obviously (in this case) once you've turned stuff you realize that thin parts are really tough to work with, just like you say at 0:30.
Brilliant! I have done several variations on the theme, but you have taken it to an extreme! Brilliant!!! I.E thin washers!!
That was a crafty solution. Thank you, Joe!
I ab-so-lu-te-ly had no idea how that was done, other then putting them between pressure blocks of some sort. Thanks for another very informational video.
absolutely awesome, now I know how to make thin steel washers for pivot bolts on a air riffle / I love you videos and your upfront straight forward knowledge and the ability to show the details Thanks again you are enjoyable to watch !!
impressive! simple but efficient way of explaining things.
Thanks!
Interesting Joe, gr8 technique!!! Thank you for sharing.
That was brilliant Joe! It seems like a lot of effort, but the results made it worthwhile.
I've been using this method for nearly 35 years. Machined numerous 10 micron spacers!
It works well.
@@joepie221 It does brother. People think a person is talking rubbish when you tell them that you can cut material 5 micron in thickness on the lathe. Think outside the box.
I keep finding these gems as I view your older videos. I could have used this technique when I was making a shim for my old South Bend lathe. Thank you very much!
Hi John. Thanks for checking in. Be sure to watch the video where I re-bore these.
Well done! Thanks for the video! Very informative and excellently presented.
Thanks for the video, Joe. I WILL be using this as I use a lot of thin shims. I've typically purchased shims or made form cutters and punched them in a hydraulic press. Usable, but not nearly as nice a finish. After 42 years in machine repair it's still nice to learn a few new tricks!
Thanks. Stay tuned. I plan to put these back in the lathe and bore them out.
Probably one of the best ways to machine such thin shaft spacers. Thank you so much for the video!
in early 2018 I'll post a video on how to rebore them. Stay tuned.
Joe, very good. The shims turned out great. This was a very good lesson for me. Thanks for sharing.
Thanks.
Very helpful Joe ... thanks alot. I thoroughly enjoy Tom, Pete and Tony but your my "go to guy" for tricky stuff.
That was an awesome demenstration of that technique Joe! Yet again, I have learned something new! Thank you !!!
Thanks for watching.
Thank you so much for this very good machining tip! I will be watching more of your videos! A good new year to you Sir!
Thanks Joe... always a good show.
Another tool in the box. Thanks for watching.
It works! ! Thanks Amigo! I did some brass washers .010" thick with your method. I couldn't be happier. Thanks for sharing.
Glad to hear it.
❤️this video! This is my second time viewing it. I like practical problem solving ideas.
Thanks for good coverage on a little explored topic. Keep them coming. Helping to flesh out my machining knowledge which has large holes in it. Take care. Doug
Spot on. I have a job that requires some custom spacers to control crankshaft end float. This video has been a great help. Thank you for sharing.
Glad it helped
I have machined thin, odd shaped parts in the past and my method was to machine the inside surfaces then fixture and fill the machined area with Cerrosafe bismuth alloy which, supports the part as a solid then machine the outside. Finally, I melt the Cerrosafe metal out from the inside of the part with fixture and now I have a part that looks like is was made from sheet when, in actuality it was machined from the solid. I had an occasion when I needed to replace a ruined grip safety for a 1900 Luger pistol. These were machined from solid steel but look like sheet steel parts. I used Cerrosafe and a fixture to machine the part's inside then back filled to make the part solid; machined the outside then melted the Cerrosafe out from the inside and now I had a grip safety part which fit the pistol and operated. Very nice work on your shims.
Is there a video for this method? I wanna watch it
Excellent stuff, thank you for sharing your expertise.
Great job Joe I finally learned how to make thin shims I am very impressed Thank!!
Thanks for the comment. Glad you liked it.
I have used the sandwich method to make copper head gaskets before. It is a handy trick for doing precision work on hard to grip bits.
Another great lesson Joe. thanks as always.
Thanks for watching
Never would have thought that was possible! Thank you.
Your the best shop teacher I never had 😊
Joe, I enjoy every one of your videos, as I always learn something. Thanks for sharing your expertise!
Thank you.
another great and very useful lesson from prof joe.
It yields a very accurate and clean part. Thanks for watching.
Enjoyed the lesson. Thank you Joe.
Glad you liked it.
Wow awesome job and thank you for sharing I find your videos very very interesting and instructional thank you so much for sharing
Excellent Joe I would never of thought of making shims that way.
Great video. I enjoy watching you work and reminds me of myself in my work approach. I always learn something new from your videos. Thank you for sharing. 🏴
Thanks for tuning in.
Love the videos! have picked up alot of cool tricks tricks in my bag because of these great videos. Thank you for taking the time to do this.
I appreciate you watching.
Joe - great idea
thanks for posting..
Very cool. That's similar to a technique that woodworkers use when planing thin sheets of veneer. They clamp them tightly between two pieces of scrap wood and plane the stack flat and smooth. That process yields a superior seam when the sheets are glued to the final substrate.
Great video with very useful information thank you
You have an intellectual approach. Your machines don't sound like it is going to hell
Thanks.
All your videos are amazing! And I am blown away by how clean your shop is. It must truly be a joy to work in such an environment. Most break rooms I've seen aren't even that clean. I learn something with every video I watch. Thanks so much for your time and sharing knowledge!
Thank you. My background is orthopedics and the shop was nearly sterile. There is no reason a machine shop has to look like a junkyard. Usually its just a lack of time to keep it clean. Its easy to get behind.
@@joepie221 In my shop I always reserve 20 minutes at the end of the day to clean up and put tools away. Makes for an easy and pleasant start the next day.
Thanks for great videos I recently purchased a small lathe/mill combo and between it and your videos I’m making instead of getting custom parts made.
Yes, great idea. Thanks for sharing.
Great Demo, love it.
Its a good solution for parts with no, or small center holes.
Excellent video! Very useful. Thanks!.
Excellent method, very well explained. Thank you!
Works very well. Thanks.
Brings back old memories of the tool room I used to work in for 20 years I’m taking easy now working in dimensional calibration 👍
Bloody brilliant Joe!
Thanks. it works well. I'll soon post a video of how to bore them out on the lathe.
Hi Joe
Another good interesting project well demo'd
We always learning
Thanks for sharing
aRM
My pleasure. Thanks for watching.
Our country needs you!
Nice work, Joe! 👍
I've watched a few of your video's Joe and as a guy who is just starting to play with a lathe and knows VERY little I really enjoy your stuff. BUT, for guys at my level simple stuff like surface speed, use or non-use of lube and what type of lubes, style of cutter etc are things that would improve my learning it it's possible to throw them in. All in all THANKS for making the effort, it is appreciated.
Alex
Such a simple solution for something I had fought with a couple of times before. I tried to make shims for antique iron restoration projects. Thanks Joe. You have a great way of passing on your experience to us amateurs.
Glad to help. Ask a question if you have a non related specific issue. I'll help ya if I can.
Great technique Thanks for sharing
Learn something new every day. Videos like this are really helpful...thanks! Subscribed
awesome easy to follow and very very helpful need shims for my diff but no longeravailable now I can finish project and possibly help others with same problem
Obstacles are opportunities. I've always said 'you can slow me down, but ya can't stop me'. I'll figure out a way around you. Good luck with the shims.
As a new lathe user I'm enjoying watching a master at work....
Thank you. Been at this full time since 1976
OMG this was the best! I was researching how to make super thin shims and ran into this! Amazeballs! I will have to try this when I get a chance.
Team it up with this one for the complete package. thanks for watching. th-cam.com/video/CbtCGEJ9z8I/w-d-xo.html
Hey Joe,
cool and outstanding show!
A thumb up from good aole Germany!
Thank you for sharing!
Freddie
Very cool Joe, nice tip!
Thank you
Very nifty method Joe - sure gives a great finish.
That was some good information, that I will put to use, may have needed to do that in the past
I had an assignment to make some copper discs .020" thick and around 7" diameter with about a 4" hole in the middle. I mounted a larger aluminum plate on the lathe that I was going to cut against. A parting tool of course would snag on thin material (especially grabby ass copper) and it is a tricky thing at best to part anything going longitudinally as we usually find out. I used the tail stock to hold pressure against an oversized square of sheet copper like you used in this video to hold pressure against the face of the aluminum stock. Now this next part of my story is what was the game changer. I used a sharpened cutting wheel taken out of a large pipe cutter mounted with a should screw onto a piece of square stock that would fit into the tool holder. With that I was able to use the compound to gently drive the wheel into the copper stock backed up by the slowly turning aluminum plate with complete success. The inner circle was accomplished in the same manner as the second step. I've used this technique a number of times to cut thin and/or soft material on a lath instead of using a conventional tool bit.
Interesting. Sounds viable.
Great tip! Will definitely keep this in mind for next time I need something thin like this
Works well.
Very interesting Joe thanks for sharing. This is like the friction drive I use
I've used friction drive on many things. Its a good technique.
I'm reminded of something I saw about 55 years ago that made me laugh. I was just a kid at the time. My Dad needed some soft copper washers for a project so we took a ride to the hardware store in the small town we lived in at the time. We went inside and he found what he was looking for but he didn't buy them because they cost too much. They were $.06 each as I recall and the store owner himself commented that yes, they were a little dear. So we went back to the shop and my Father busied himself for a little while building some kind of jig and he got busy making his copper washers. They worked perfectly when he was finished and I thought my Dad was really neat and the smartest guy I knew. Oh, and the washers and the blanks he used to make them.........pennies.
Just excellent Joe Thanks.
Nice demo well explained, thanks
Very helpful video. thank you for putting this one up.
Glad it was helpful!
Well you learn something new every day. Thanks
fantastic and impressive!
Putting rolling papers between the layers would probably improve your odds. You would lose rigidity a bit more than aluminum, but aluminum spinning on steel will erode it and on aluminum it will gall. Great demonstration on pinch turning. Always good information from a great machinist. This guy is who I wish I could have started training with. Had to teach myself. And I'm not a good teacher. 😂
The snag with self-teaching is we learn the mistakes.
Excellent demonstration of cutting shims.
I will eventually share my setup to bore them afterward. Thanks for watching.
I used to do that all the time, it works great!
Nice one Joe!!
WOW!, you have been trained by the right people in the past from the looks of your shop, a beauty!
Thank you. I'm very fortunate to have it at my disposal. We've done a lot of very interesting projects here.
your Harrison lathe looks in pretty good shape, has it been repainted, these lathe are a rare find, wouldnt mind getting my hands on one, is it 15 x 50'' model ?
Joe, I enjoyed your video very much. Many would very challenged with such a project and in this world that is when another shop decides to give the job to a supporting shop. I also appreciated how you told us how,what kind of,and when to use certain tools and when not
to. Finally I really respect that you use manual machines.. I believe anyone who goes into the trade is helped a lot by learning on them as sometimes (at least to me) manual in many cases becomes the best way. Best regards, Go Pflu football!
Awesome video. I’d have just made a die. I like watching your videos and perspectives. Wish I could have cut my teeth in a shop with more machinists like you
I have a very similar project with graphfoil and I am waiting to see the second half of this because this could save me so much time. Thanks for posting this first video.
I started putting it together, yesterday. How thick is your foil?
Joe Pieczynski 0.060" per sheet. it's just so fragile.
Can it take compression force without crushing?
ABSOLUTELY BRILLIANT!!!
That's pretty slick!
great stuff Joe! thanks for the technique!
I see all kinds of possibilities, thanks Joe
Jim
Pressure turning solves a bunch of problems. Thanks for the comment.
Great video, can't wait to try this out....
Watch the corners !!
What brilliant! Thanks for sharing. John
Again perfect for pinion shims. Thanks and so simple...👍👍👍👍
good tip, looking forwards for part 2
I'm going to let you guys think on this one for a while. Stay tuned.
