Looking for suggestions on a design for a small furnace torch. If I can buy parts cheap, or buy something intended for another use, would be best. I need to melt aluminum. Someone suggested a weed burner, but I've never seen or used one. I would like to use an air injected propane torch. I have a large claypot with a hole drilled in it ready for the torch. I have cast some chess pieces into ceramic molds already for this project. Gonna try my hand at anodizing once they are cast! Any advice on the torch / furnace would be very helpful. This is only for hobby, but I want a sound setup built to last.
