Hi
My Sheraton 9 from the 1950's 60's came with its original 3 burnerd chucks..The teachers at the tech obviously didnt change chucks that often.. the two 5" 4 jaw chucks were not worn, but the little 4" 3 jaw was not that good . I just had a close look at the 3 jaw. the flats on the jaws that clamp the work, have Vgrooves worn into them.... I used a diamond plate and re profiled the flats backto flat ............hope it works OK :? i also gave the chuck a polish with a coarse then fine file and emery cloth.. it looks new again :2tsup: i plan to use this chuck on my Hall dividing head which is almost finished :)
