This picture depicts two propane burners with air chokes, mig-welding tip nozzles, and a shut-off to use just one burner. If budget is a major concern and your forge design is smaller than 200 cubic inches (roughly) a propane bottle torch can be used.
The picture depicts a dolly style forge cart which holds the propane underneath with tool storage. The propane bottle is removed and place away from the forge when in use.
Use a metal file, examine the amount of sparks produced when on a bench grinder. Anneal the piece and examine again. Quench the piece in water at an orange heat and try again. Try making a round bar square if you have an anvil. Make a twist in a square bar with a vice and pliers. Heat a scrap metal file as hot as it can go. If it turns white and ‘burns,’ the forge is efficient enough to faggot-weld with. If it does not reach this temperature, it is fine. Try faggot-welding two rods together using borax.
