I picked up this old die filer a while back and now have it torn down. It worked, but had a noticeable knock. I found the bronze bearing block hole is pretty worn from the crank pin. The crank pin measure .530", the bearing block hole measures .544" north/south and .540" east/west. So it looks like I need to either make a new bearing block sized .001" over the pin size or bore the block hole back to round, about .545" and make a new crank pin to .544". Have any of you guys tackled this job before? Looking for advice from someone who's done this before. These machines aren't too common any more, but most that are still around are pretty worn out. I'll try to get photos of the block and pin tonight. So I don't think I'm the first to encounter this problem. Thanks - Steve
