This device is commercially availble. It takes standard ER collets, any
machine shop supply has the collets. Unfortunatly, I don't remember where I
saw it or who makes it. Doing a Google serch yesterday on some lathe related
subject and it came up.

Hi Bill-

I know you make faceplates and other assorted goodies, so I figured
you may be a good guy to ask-

I'm looking at the possibility of mounting an adapter of some sort to
my Delta 1" x 8 tpi spindle that would allow me to use a more-or-less
standard collet like the ones you'd find in a metal working mill or
lathe.

The theory is that I could then mount various cutters in the beast so
that I could machine some of the parts for the metal lathe I'm working
on with the aid of some other fixtures that would be easy enough for
me to make myself. Offhand, I'm envisioning an adapter that is about
1.5" in diameter that is around 3-4" long that can screw onto the
headstock thread. I can put a drawbolt through the headstock to pull
the collet tight.

I'd make it myself, but it's bound to be nicer if you can turn it on a
metal lathe than if I make it with a bit of pipe and a welder.

Any chance you've got the tooling to do such a thing? If so, how much
do you figure an item like that might cost? I can come up with more
specific specs if you think it's worth your while to take on the
project. Otherwise, I'm sure I can come up with something that will
work by other means.

Thanks!
