Topic tags/keywords: question

I have a student in my high school wood shop that only has one arm. He really wants to use the lathe to turn small projects, for example pens, segmented bowls, but he has trouble using the chisels with just one hand. I was wondering if anyone had suggestions for building a jig to hold the chisel in place while he worked. We do not have access to a metal lathe, we only have a couple of small lathes and one large Powermatic. He is a smart kid with lots of ambition and I don’t want him to miss out on a learning experience.
Thank you,
Eddie

I would look at contacting a dedicated turning organization, local turning groups, and perhaps a disability organization.

https://www.woodturner.org/

A jig likely could help stabilize the tool. I would assume side to side stability is the issue. Maybe finding something that would allow some resistance in that horizontal plane but is not fixed. A bungee or similar around the shaft of the tool near the handle and then have it hook onto a fixed place on the stand to pull the tool down on the rest. May allow him to concentrate then on side to side movement. I would try a few variations yourself in the shop to see if you find it safe and a benefit or not. Cords however would make me nervous about getting caught and wrapped onto the piece. Personally wouldn’t go that route and would look more into just figuring it out one armed.

He will be best be served just practicing a lot and maybe make a fake set up that mimics the motion and just learn one armed. Ideally if resistance can be added so he strengthens those muscle used in the side motion it would help him keep things in control. Maybe contact a physical therapist and see if they could come up with some ideas that might help train muscle.

Only a possibility but may work one handed for light work as you described. Not sure about segmented bowls and the like but pens, bottle stoppers, etc may be very doable.

You say “one arm”. Does he have a partial arm, say a stump of a forearm? If so, a cuff over the stump end with an extension and a clamp to old the tool might work.

+1 i like this idea,looks like it would give good control,at least on small turnings.

If you think this would work and are in Canada I have a setup like the Sorby hollowing tool that I would be more than willing to donate. It is a Don Pencil. I think you would also need some sort of captive for it
