Check with your local used machine tool dealers, they often have

Alright, sounds good.

I don't have a problem with building the handwheel assembly, I just
don't want to do the ID threading on the collet drawtube itself.
Looks like I should be able to find a used or broken part that I can
adapt.


single point threading of the draw tube oddly enough, doesnt seem to
give as good a fit as does a tap for draw tubes, which I always found
really odd, being thin wall tubing. Most draw tubes are tapped.

I single pointed mine, not knowing any better (first lathe project).
Anyway, it works. I did have a hard time getting a good finish on the

I later replaced the adapter with one from Royal.
