Cast iron can be braized, I think that is the right word. They used a brass welding rod. I just had a broken pedal repaired. A good welding shop, should have no problem.

Dale Probst, Registered Piano Technician suggested that I would be better served by posting my question to the pianotech list. My question: I am just learning about pianos. I recently purchased a Hamlin and Mason piano Model B manufactured in 1940 per the serial number B50186. Tracking a squeaky "sustain" pedal has lead me to the underbelly. The cast iron assembly (part # s696) supports three rocker arms (part #s s693, s694, s695). The movement of rocker arm part # s693 is sloppy and the source of the squeak. The metal area around the rocker arm and pin shows signs of cracks and previous repair (including a pin larger than the others). Being cast iron, I am told that welding is a very unlikely solution to repair the assembly. Is part replacement my next step? Where can I find parts? Thank you.
