I've got a Richmond dividing head with a 1 13/16" x 12 tpi spindle that is bored 4 MT. Given that none of my chucks or collets have either of those dimensions I was considering making/adapting a flange to accept the D1-3 camlock chucks/collets/faceplates that I have for my lathe. Has anyone else done this? Making a camlock nose would be a PITA so it would be easier to start with some parts from a scrap Bantam/Chipmaster/other headstock. Anyone know of a source?
