[TheForge] Welding cast wood stove baffle

Mon Apr 8 19:47:32 2002

Just a thought, but how about making a frame and filling it with some green
sand. Then use the part to be welded and push it into the sand as if you were
making a mould. Then heat the whole piece to at least red and then using some
scrap cast, flow the broken area together, cover with vermiculite and let cool.
