TBC Bushings for 30 Caliber Cartridge Pens

$ 11.00

Turning Between Center (TBC) Bushings custom machined to finish the top blank to complete our CNC engraved 30 caliber cartridge pen kits. Set includes one upper and one lower bushing. Design by Tim Geist.

These bushings require a 60 degree dead center for the headstock and 60 degree live center for the tailstock to use properly. They do not mount on a mandrel.
