Stupid question…..

[BULLWINKLE]

All the pens I've done were done on a mandrel. I'm thinking about going to TBC.
Question: how is it mounted on the lathe with the bushings but no mandrel ????
Thanks

Yes and no.

There are TBC bushings which are typically better "centered" and fit in the 60 degree live and drive centers.

You can use the same bushings as used on a mandrel but they are not always round enough.

You can also simply turn without bushings and just use calipers.

The only stupid questions are the ones not asked.

I use these too but not as much

The PSI one posted by Drew at Exotic Blanks is a pretty popular one, and economically a pretty good value.

Just make sure you don't tighten it down too much end to end. I've found you can get them slightly out of round.
