Do you know of a source for a drawbar and adapter or drawings
so I can make my own?
FWIW, I have a Sherline mill and use their WW collet set which is
great. They’ve also got a 8mm collet adapter PN 1163 but that’s for
a Sherline, of course, and not a Unimat (don’t know the taper on a
The point I wanted to make though was that scattered throughout
Sherline’s helpful and interesting “Accessories Instructions” pages
(http://www.sherline.com/accessor.htm) there are a few papers on
collets and collet adapters. Perhaps you could find something in
there to help you modify or adapt an existing tool to your particular
application. I know I have on a number of occasions.
I’d also recommend the lathe and milling groups at Yahoo. Again, I
know it’s not Unimat specific, but the guys in the Sherline group at
Yahoo (http://groups.yahoo.com/group/sherline/) are very helpful and
knowledgeable. I’ll bet if you asked them how to adapt the Sherline
8mm collet adapter to your Unimat, for example, they’d help you out.
Actually they’d probably go ahead and do it, post pictures and ask
you if you wanted one for Christmas. That’s the kind of group it is.
