Ive got an old L1 chuck'ed Hendey lathe. The 4 jaw is worn out. Like really worn out. I want to replace it . I have a 3 jaw Bison that works great but I need an adjustable 4 jaw for barrel threading work which I dont do often but do do occasionaly. I was looking at a Bison 4 jaw since they seem to be the only company that has them ready to go $1400 which stings . Unfortunately they are not available off the shelf. No one else besides Pratt makes an off the shelf unit and those are about double the cost. I dont know enough about chucks to know whats compatible if I want to buy a generic 4 jaw independent and match it up to a L-1 mounting adapter.
Any ideas?
