I've adjusted a few babbit crank bearings and will be honest, I never bothered to mike the shaft, just measure and remove shims until things got tight then added some back. Do you know if this was something more popular with auto engines than tractor and stationary engines? I'm thinking the "farm stuff" was ran slower and maybe more forgiving. I guess real repair shops may have been the ones using them, as crank grinding machines were few and far between. Certainly a cool item! I work with a guy who's father just retired as an engine machinist. Next time I see him I'll ask if he ever heard of one of these.
