Lund-in response to your heat treating question, I would refer to a book that the aws(American welding society) makes. It's pretty much the bible and tells you what heat, how long, and any procedures or precautions you need to do or take for every type of metal. My dad actually has 2, from 1997, next time I stop by his house I'll try to remember to look and I'll let you know. Sorry for bumping this post
