So OK ...
a. we are pretty sure the pins in most cases are not bronze... perhaps in all cases?
b. do we have any confirmation that the gudgeon hole size built to was really to .005in.? say to +- .001? always have to have a +-?

AND that two holes drilled or punched in that stock and placed 2 inches apart and welded together could also have a combined specification of .005in in alignment with the same, same hardware placed 2-3 feet apart?

I'm having a problem with .005in.
