Ed, what wire would you recommend for building up a worn pin housing using MIG in a Bobcat (skid steer loader) Bobtach attachment mount? The housing is acted on by a pin on the end of a hydraulic cylinder that controls the tilt of the bucket or other attachment. It is basically just a hole in the attachment mount, there is no replaceable bushing available. Also, what is the best way to machine the surface after building it up?
