I did this & it worked a treat, as they say. *I hadn't thought of the
Unibit, but it was just right. *I turned a 3/4" stub on the piece in the

Thanks,

Glad everything worked out! I was also thinking of something similar
to what Jim Wilkins suggested for holding the ID concentric and making
a stepped holder out of aluminum so that you could press it between
the chuck and the tailstock. I just wasn't sure that you'd want to go
thru all the trouble. But, again, I'd glad you got it done. Spacers,
washers and bushings are probably the most common things made on my
lathe.
