- This video will show you a device called an expansion arbor. It works well for holding inside a part bore for second op machining on a lathe. You think you've seen it all, think again. Watch this video for a whole new perspective on expansion arbors.

Hey Joe, It seems a bit lame to repeat the accolades offered by so many others, but I feel compelled to say that you're videos are ABSOLUTE GOLD to a 60-year old learner like me. Also, to the guy that queried about writing a book, don't mess with perfection this (CZcams) suits your knowledge, personality and style to a tee. I vote you No 1 CZcams contributor of all time. Best regards N.
Thats a great compliment. Thanks you for taking the time to watch and send the message. Much appreciated.
I have worked in engineering all my life,& you need more than one life time to learn it all,I am 70 now, you teach me many new things thank you.
How could 10 people give a thumbs down? As someone new to machining I find this stuff priceless! Thanks Joe
Hi, Joe,Alan here in UK. We really enjoy your videos, and as a toolmaker who is still working after qualifying over fifty years ago still find there are things to be learned. We have a job which is a tube and sticks out of the chuck far enough to need supporting on a centre. Your expanding mandrel in a blind hole has given me the solution, and we can relieve it so as to be able to face the end.
We like your direct no nonsense style, and I bet like us, every aspect of your life is precise, to the point and truthful.Many thanks, keep it up. Incidentally we use Hardinge and Cincinnati machines along with our native Colchester and Jones and Shipman.
We're old school!
Hi Alan. Thanks for checking in. Glad to hear I gave you some food for thought. I like when someone takes one of my presentations and works it into something else. Evolution at its finest. Take care.
Mate there's no doubt about you, just brilliant. Many many thanks. Jim.
Thanks Jim.
Thanks Joe. Man after my own heart. Can't stop working out new ways to fix old problems. I'm 68 and just started learning lathe work. Never stop learning new tricks. Body shot, brain still active.
Another good one Joe - in particular the "O" ring trick. Your close up video these days just gets better and better.
Thank you.
The O-ring arbor version was a nice implementation, and your afterthought pointing out the need for drilling a short recess to the major diameter to clear the unfinished threads under the head on most countersunk screws was pure gold. Most people would miss this, and the arbor would expand unevenly as a result.
One quick and dirty kludge I have got away with for lightly skimming the outside diameter of (say) one or two bronze or plastic bushes to ease the fit, is to use an expanding reamer of the Sutton Microset style, chuckng the shank and supporting the entry end on a running centre in the tailstock. Don't overtighten or you'll mark the bore!
For thin items needing accurate work I like to use heat shrink fits on solid arbors so there is no distortion. Lots of good info in this video on expansion arbors, thanks for sharing the tips and tricks.
Been at the Job Shop game for 36 years. Made expansion arbors many times. Some things here have not thought of before. Absorbed, filed away for future ref. You CAN learn something new every day. Thank you very much for your generous share of cleverness.
Glad to do it.
Fantastic ideas, 45 years in the toolroom and never dreamed of that!!! Learn something every day, thanks Joe!!
Nobody thinks an expanding arbor can be used on a blind hole. It a simple solution.
Thank you Joe. Do you ever consider how you, with the aid of this media, are adding to knowledge and capability worldwide ? So generous!
Thanks. I would like to think these help.
I've never even thought about making these until now. Thank you ever so much, great video!
You, sir, are indeed a Sneaky Machinist! Hats off!! Thanks!
Beware the sneaky !
Outstanding as usual. I watch all your videos but every time I do so I ask myself, why is he not wearing a cape? Seriously dude, great stuff. Thanks for making the effort to share.
I'll look into the cape. I like it.
Joe, I so appreciate the creativity you bring to solving challenging jobs. Your positive, upbeat approach must reflect your approach to life overall. Thanks for sharing your ideas, and even more for sharing your attitude.
Thank you. I love a good challenge.
this format is ideal, concise useful tips that are easily recovered from the youtube library if you should forget about them
Is there a way to "like" this video twice? A few dozen times?
Joe, that's how useful some of your tips are!
👍👍👍👍👍
So the technical content is excellent. But I must say the narrator and his sound effects (whistling, etc.) are AWESOME! Thanks for posting…
Thanks Joe as it turns out I just today needed exactly this type of solution was trying to figure how in the heck I was going to hold the thing and well now I will just make a Joe Pie Special and continue along like I knew wast I was doing all along. Thanks again Joe.
The O-ring arbour is very clever - I can think of several uses for the principle / idea already. Thanks for all of your videos .
It amazes me the innovative ideas you come up with! This one goes into my permanent library of machinist tips. Thanks for the video & keep them cummin! JB (San Diego).
Best tip I've seen in a couple of months.
As usual Joe .. Great content and so down to earth with your approach of " No problems, just solutions to those problems" fantastic thanks for sharing.
Amazing and well done. I was just right now having a problem making plastic fittings for a job. You are correct, I was using an exhaust pipe expansion tool to hold the fittings but the forces were breaking the plastic. Also, it looks like the rubber O-rings will increase the friction for holding over the friction of the steel. Very much appreciated and it comes at such a good time. Thank you, helped me out very much. :-)
I just got a co-op working in my first machine shop. I am so excited to have a Chanel like this to help me solve problems. Love your videos!
Thank you. Shoot me a question if you hit an obstacle.
Thanks for these brilliant techniques, not only clever ideas but simple to produce. Keep up the good work.
Outstanding video! It's nice to have your years of experience available to all of us. keep the videos coming.
Hey Mr Pi, every time I run into a problem with a setup or just a general question about machining I know I can rely on you and your vids for the answer. I just want to thank you for taking the time to share your wealth of knowledge with us hobby types. The insight I have gained from your vids is priceless. Again Thanks
Thanks for watching. Glad to help.
Great tips. One of the interesting thing about great tips is how obvious they seem after you have been told, as opposed to before when how to do a job can be a real conundrum.
Thats very true.
Joe keep it up! Straight up machining to the point, always learning something! Thanks!!!!
As always, I've learned more from your 15 minute video than I ever do watching an hour of the other guy's machines go round and round. Your videos are always informative. Thank you.
That was great Joe. Very, Very clever design of the O-ring arbor. Thanks for posting these tips.
Thanks for the expanding arbor tips. Keep the videos coming Joe! Thanks
Everything you show us definitely stimulates my thoughts. Thanks so much for taking the time to share with us your endless tricks and solutions.
Thanks for passing on your knowledge and experience. So simple but so useful. Great addition to the tooling and thanks again👍
Thank you for sharing your knowledge and please continue to do so. Its changing my life for the better.
Genius, Joe, This is a fantastic, elegant solution.
Thanks
Joe, your ingenuity always amazes and teaches me. Many thanks.
Thanks for watching.
Absolutely excellent - well done Joe!
I have never thought of the o-ring, but then again I'm a new guy. Thanks so much for All the solutions to challenges in the shop you offer.
Glad to do it. Been at this full time 6 days a week for 40+ years. I've had my fair share of challenges. Thanks for watching.
Joe, I have watched this video a couple of times over the past couple of years and just watched it again because I am going to need to make a couple and wanted to make sure I got it right the first time.
Thanks for the great content and your great attitude.
That o-ring idea is soooooooo much easier than what I have been doing. Thankyou. Kilroy loves you. Funny
I was just about to go out to the shop to make some expansion arbors. I'm glad that I found this video because you mentioned a few features that I hadn't thought of!
Joe I love all your little tips on doing tough jobs.
Last night I was trying to work out how I'm going to hold thin wall parts without a through hole, and I remembered that you had a video about expansions arbors years ago so I thought I'd rewatch that video. While searching I found "expansions arbors - no through hole, no problem". Perfect! Squeeze O-rings so they expand! Thanks Joe!
- Happy Hobbyist
O-ring arbor- inspiring :)That is a very cool and useful idea Joe. Thank you very much for sharing so much of your experience.
These are my favorite types of videos (work arounds) seems so easy but the thought put into gadgets to help you get things done that's the magic. Thanks Mike
you definitely got me with that O-ring arbor. Genius ! Thanks for sharing ;D
Your channel helped me a lot while building my hobby mill from scratch.
Nicely presented, Joe. Filing this one away for the inevitable time when I'll need it... Thanks!
Greetings Joe. Thanks for the great info on expansion arbors, and especially about the small counter-bore to allow for the unthreaded part of the flat head screw.
This one was a little pearl! Like all the others really... Joe, you're a class act!
Amazing ! I cannot thank you enough for sharing this in addition with a so clear and valuable manner !
Glad it was helpful!
Wonderful tool and idea!!!
I'll make one this friday...
Thanks for sharing!
Another great video Joe! Always look forward to them and always learn something. Thanks
That's the slickest use of O-rings that i have even seen. Solved my problems
Great tip about expanding the arbour then machining to required dimension.. great videos
Very clever Joe Pi. I've never seen the reverse draw bolts for blind holes. I will most assuredly be using that one. Good stuff as usual.
A couple of great ideas there Joe, thanks again. I tend to use a lot of plastics in the lathe and you have just helped make things that bit easier, cheers pal !
That's thinking outside the box. Thanks for your efforts Joe.
I've watched a few of your videos and enjoyed them all but this video convinced me that I need to watch more. Thanks for sharing your knowledge!
That o-ring arbor - pure gold again! You solved a repair problem again. A great many thanks from the happy amateur.
Thanks Joe - been working with some thin wall tubing for air whistles and your first style expansion arbor will be just what the dr ordered to keep from crushing it in the chuck jaws.
Thank you SO much for these tips. For others in the trade it might be old news, but I am learning every day. ESPECIALLY the tip of putting some pressure on the bolt first before turning the final OD. That is just brilliant. I am so glad I came across your site and subscribed! All the best for 2022 Mr. Pie!!
Just brilliant! So many things to learn from the experts, so little time...
Thanks Joe, brilliant! I'm in the UK and been a subscriber for sometime. Every video is explained well, stimulating and a "lightbulb" moment for me. Please keep them coming
Great video, and great projects. Specially the blind hole mods. Thank you for sharing.
This channel is such a wealth of information and ideas. Thanks Joe.
I appreciate that!
Mr. Pieczynski you never stop amusing me, have a nice day.
That was really good Joe, I liked the o ring arbor.
One shop I was in years ago liked to cut a 14 deg angle on the head of the screw and the arbor.
This made the arbor and screw mach and expand easier.
Thanks again.
Very clever! I could have used this a lot of times but I know it now. Thank you, Love your videos. I am self taught and wish I had the internet 40 years ago
Great ideas! The blind hole variety will be a life saver, thanks Joe!
Thanks for sharing. I always look forward to your informative videos.
good vid as always..been using expanding custom collets for blind fastening of pipes and tubes..also tailpipe expanders have saved the day in this regard a number of times
That is Brilliant!!, just made me a more powerful machinist, wish i could give him 2 thumbs up, thanks from Canada !
Glad it helped.
Incredible. And you're offering all that kind of experience for free on CZcams.
Great vid, Joe. I've made the regular slotted type for a number of jobs, but had never thought of the o-ring type. Great tip! Taught this old dog a new trick. Thanks much!
I have to say, great idea and thoroughly presented. Many thanks, sir!
In my opinion the best video on CZcams for expanding arbors! Both are great & very easy designs!👌
Thank you.
your expansion arbor just advanced my ring and collar work... thanks much...
I love these versions of expanding arbours. I have no experience at all with machining, but bought a mini lathe last year and have been looking for projects to try and make ( mostly, all I've made is a mess, but I'm still enjoying it). This has become my new project for February.
Thanks Joe, always impressed with your methods/ideas.
Great video, never thought of making those! Thanks Joe
Joe there is or seams no limit to your knowledge i have to keep watching and rewatching to get all of the tips and tricks you use thanks for shearing this knowledge
I appreciate that!
Great. I'll go the double O ring with a screw operation from either end and a gentle conical slope. Thanks again Joe. You are a very generous person.
My pleasure.
Thanks for the idea! Its always good to have many ways to hold the work.
Very helpful video Joe! Thanks as always for sharing!
love all your videos joe ......keep up the great work
Great stuff Joe, I did some metal work in school 40 years ago, recently bought a small 14" lathe, been watching your videos avidly, my horizons are expanded more and more, keep it up, great work. Donald From Scotland
Pure gold. Thanks for the practical tips. Subscribed!
Awesome video, Joe. I breathed a sigh of relief when you picked that bit of fuzz off the o-ring. I think I'll sleep better now tonight... Ha......
I can't believe I didn't do it sooner. It made me nuts after I watched the clip too.
Yet another excellent video from you Joe.Many thanks for the video's you post
Great video Joe, that will come in really handy in the future, thank you for being so generous with your knowledge
Hello from John, Australia. I just subd after watching this vid. I use many of the ways you show here for work holding. I did learn from you some new ideas. Good for all watching! Cheers from John.
Greetings from Austin Texas John. Thanks for subbing.
Always sharing helpful ideas. Thank you, always!
Oh how I wish you were on CZcams 40 years ago when I first started machine work.
Really enjoying all the tricks that you’ve shown!!
Great video Joe! Creative work holding.
Joe, All I can say is you never cease to amaze me. :-)
Thank you Joe. I look forward to many, many more from you. God Bless!
I have a list, I just need the time.
