On the same note, I have a '37 Knuck with stress cracks on the left side, right below where the cylinder bolts on. Is this a common weakness? I was wondering if a competant welder/machinist could repair such cracks so the cases could be usable with a stock motor re-build--the motor may have to be bored, but that would be it as far as mods. These thin cracks were fixed for a long time with "JB Weld", but I want a more permanent fix, especially since they are the original cases.
Any help/suggestions would be great--thanks in advance.
