Hi guys, I hope I really explain this well. I'm fabricating a forge normally used by blacksmith for providing heat. It is also employed for providing heat for heat treatment like annealing, normalizing, etc. I'm working on the power; electric source. I intend to use an electric blower to supply the air into the hearth (the place where the coal will be placed). This blower is to have regulating valves to control its speed. I haven't seen anyone before and I haven't gotten good material on it. I wish to start the fabrication soonest. I'm also stocked with the type of metal to use. please, any contribution or ideas will be appreciated and welcomed.
