That’s a 10” Bison Set-Tru. My workhorse chuck. I make soft jaws for it. If you’ve never made soft jaws for a lathe you can’t imagine how awesome they are. You need two-piece jaws to do this. Details on request. With the Set-Tru I can dial it in at a given diameter and the sucker just REPEATS. I dial it in like that multiple times a day; it’s worth it, and I’m fast at it. Keep everything nice and concentric, even if it’s not technically necessary for the part, and the work just flows from there. I also have a 10” Buck 6-jaw Adjust-Tru for it, but only with 1-piece outside jaws, and a 12” 4-jaw independent, and a Bison 5c collet chuck.
