As a matter of interest, a question........ If the gun body has to be cut into 3 or 4 pieces, why can't the gun be cut straight using a torch (or body) held in a rolling jig as used in cutting steel plate. Or better still, using a plasma / laser cutter. Or are the bubba type torch cuts meant to be like that, just to make life difficult?

What does the bump to read note mean tr63?
