My jaws have a manufacturing problem that does not allow me to reverse them for all the years I have had I never reversed them.
Bob, I was thinking about that and that has to be a consideration too.Remember that besides fitting the lathe, the chuck also has to hold work of various sizes. As the O.D. of the work gets bigger, the jaws start to extend beyond the chuck. Eventually they will not clear the bed. At some point as the chuck size gets larger, it will hold smaller work, not larger.
