I purchased a Monarch Model 62 lathe. It has a 315mm ~12.5" chuck on it which only came with 2 hard jaws. There are no markings on this chuck other than 1,2,3 on the jaw locations. The jaws have two bolt holes 88mm apart. They have a 16mm groove instead of a tongue and this runs in both directions.
I could make my own soft jaws but would like to get a set of hard jaws for it but cannot find any jaws which fit these parameters.
Jaws I have are about 5-3/16" inches long, 1-3/8" wide, tallest jaw is 2-3/8", 2nd is 1-5/8", shortest is 15/16"
I believe this is a metric chuck the groove are 16mm wide and bolt spacing is 88mm.
It is a cam lock mount.
If you have any insight please respond.
