      Hi, Pete

      I made such an adapter as one of my first Taig projects.  You can see a picture of it in the photo files section (Stlbill's Photos).

      It wasn't that difficult.  I only had to acquire a 3/8-24 tap.

      I bought a 3/4-16 X 2 inch bolt at the local hardware store.  The bolt I found was hardened. I tossed it in a charcoal fire until it was red hot and allowed it to air-cool.  I cleaned it up.  Sawed off the head.  Faced the end.  Drilled and tapped it.  I hand filed two flats to facilitate easy removal.  I think I used a scrap of thin brass to wrap the thread to protect the chuck jaws.  I faced a 3/4-16 nut down to about half its normal thickness to use as a jam nut.  It was a fun project for someone just learning to use a lathe.

      Hope that is helpful.

      A friend has acquired a very old duplicating lathe made of Taig parts with a spindle nose that is a male 3/8"-24 thread to fit either an included spur center or a drill chuck.  She wants to mount a Sherline 4 jaw chuck onto this headstock and I was wondering if any of you know of an adapter to mount a Taig chuck onto the Taig drilling tailstock?

      This is an adapter with a male 3/4-16 on one end and a female 3/8-24 on the other.  The 3/4" end can be any length but the 3/8" socket has to be deep enough for the tailstock spindle.  I could make this but it would be tricky for me with the large threads to form.
