Just noticed the arm on my Chinese drill press that holds the table is cracking. Think I'll try to braze it. The arm comes off and it will fit in my propane BBQ. Will that get it hot enough so I can braze it? Or should I heat it with a big propane torch? How hot do I want it before I try to braze it? Don't have a rosebud, about the biggest torch I have is a cutting torch. Is there a chance that could work? Or should I look for a big tip for my torch? Could I braze it with a straight acetylene torch? (Prestolite) Have flux and rod. Going to drill a hole at the end of the crack and grind out a "V." How deep and wide should the "V" be? Any hints?
