We have a ridgid K-50 that has been dropped off a moving truck. The motor still works, howeve the cast alluminum body has been broken in several places. We would like to repair it prferably with a used body that the motor is'nt working in.(cheeper) does anyone know where we could finda used K-50? P.S Has anyone used that new "allumiloy" solidering stick? Does it work?
