I made a couple of steam cyls but cut the intake and exhaust slots slightly off, I brazed them shut and tried re cutting. I broke two 1/8 end mills and one drill bit, even drilling into the brass is really tough. My question is does cast iron and brazing rod become very hard after brazing? I did'nt seem to have any trouble cutting the first time before brazing.
