Expansion Arbors --- No through hole...No Problem..Take a Look

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 (YouTube) suits your knowledge, personality and style to a tee. I vote you No 1 YouTube contributor of all time. Best regards N.

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!

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.

Mate there's no doubt about you, just brilliant. Many many thanks. Jim.

I've never even thought about making these until now. Thank you ever so much, great video!

Fantastic ideas, 45 years in the toolroom and never dreamed of that!!! Learn something every day, thanks Joe!!

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.

Thank you Joe. Do you ever consider how you, with the aid of this media, are adding to knowledge and capability worldwide ? So generous!

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.

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.

You, sir, are indeed a Sneaky Machinist! Hats off!! Thanks!

this format is ideal, concise useful tips that are easily recovered from the youtube library if you should forget about them

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.

So the technical content is excellent. But I must say the narrator and his sound effects (whistling, etc.) are AWESOME! Thanks for posting…

Is there a way to "like" this video twice? A few dozen times? Joe, that's how useful some of your tips are! 👍👍👍👍👍
