Well, today was better,I only broke 1 bit and a 6-32 tap.I always drill small hole first,then go up. My bud,Bob W told me he had same deal with an iron Jaeger plate and guard. We both agreed that next time he fires up forge, we gonna gather up ALL the cast stuff for future projects, and give em the ol hot foot and burial treatment. Some carbide drills,too. Thanks guys. Dave
