I am just beginning to get my feet wet in this field. I don't know a darn thing about how to work Iron. I have purchased 2 books though, $50 Knife Shop & Step by Step Knifemaking. I purchased some Fire Brick yesterday and Refractory Cement to use in the joints. I haven't come up with a design yet that will be functional yet. I hope I don't blow myself up or something. Well, Howdy again and I 'll talk to ya'll later. Rooster.
