Thanks!
Ran into a slight snag with the second caliper. The glides for the pads are really worn,gouged in fact. I grabbed some nickel/silver brazing rods,but need to preheat the casting to about 700 f first. Dont have a kiln so still trying to figure this out.
Maybe some fire bricks and a tiger torch would make a nice temp kiln? I do know there is cast iron weld wire for a mig,but I need a machine that has at least 135 amps to use it;my Lincoln is about 90-100 amps,not enough heat.
