Glenn,
Union Carbide has a book from the 60's / 70's, as mentioned in another response Ron has one, and a couple other "how to" metalworking books found online are available. Most books give a basic explanation of process and set-up, but it's nice to have "live" directions available. If your son has questions I'd be happy to help. The process is easy once you get over worrying about destroying your panel. Of course practice, practice, and more practice helps...
