Topic tags/keywords: lathe adapter pen turning

I have an antique lathe I’m setting up and would like to try pen turning on it. However, it was made in London and doesn’t have standard American threads on the headstock shaft. I got a quote from a local metal shop to make an adapter, $65.
After some brainstorming I thought of mounting a piece of UHMW to the face plate and turning a stud on it that could then be threaded to fit a mandrel. I have never worked with UHMW so I don’t know if it would be strong enough.
Anyone know if this would work or any other ideas, please let me know.

Can you post a photo of the headstock?

Why not just bring your old headstock to that machinist, and ask him to make a new shaft, with 3/4”X16 standard threads on one end. Then, the sky’s the limit for accessories you can buy.

poopiekat, The lathe has been passed down from my dad and grandfather. It is around 180 years old. I would like to keep it as original as possible.

It is going to be hard to beat a price of 65 dollars for a custom adapter. In the picture I can not quite figure out what is stuck on the current headstock. Is that some kind of drive center? Does the headstock have a hollow cut to a morse taper? If so you could make pens just by buying a morse taper jacobs chuck.

Minorhero, Yes, that is a drive center. The shaft is solid and threaded 9 teeth per inch. I think I may ask the metal shop about making an adapter with a threaded shaft on a flat base that I can screw to the face plate.

There looks to be a rod stuck into the outboard side. Just remember to remove that before powering up the lathe the first time. The rod looks like it might be rusted in place, but it seems unlikely to me that the rod is actually fixed in place so that it can not be removed. You might want to talk to the folks at owwm.org for information on restoring the lathe. This kind of thing is pretty much their bread and butter.

Minorhero, If you are referring to the rod I’m thinking of, it is a lock for the shaft. It is loose and the shaft can be turned in further to make more room. I am in the process of repainting the parts and building a bed and legs for it to mount on. Hope to be done with it soon. I will post it as a project when it’s done. I went to OWMM.org but didn’t find anything listed for Holtzappfel, the maker of my lathe.

Your manufacture is well known. You may want to check out google books….
