I'm looking to make up some 3/4" straight shank set screw endmill holders. They would be basically like the tormach set screw holders, but not hardened and ground. I like the tormach holders and have a couple, just looking for an excuse to use the new lathe for something useful!
Is there a suitable material for making these that will hold up to home shop occassional use? I'd prefer not to heat treat since I don't have a real good way of grinding these when done. I have a 10" hunk of normalized 4340 rod that is leftover from a custom axle. Its properties seem pretty good compared to other steels until you get into tool steel.
If there really isnt' a suitable (non hardened ) steel for end mill holders I'll just make up some holders for non critical things like tap guides and indicator holders, etc.
