Hey Gus I would like to learn a bit more on this furnace you have built. I realize it is not for just anyone to do but I would like some details on this unit you made. You mention a new torch, can I ask what type or model and how many BTU it is rated. Is it a fan forced furnace? Okay I'm sure it is but how are you going about that end of it.

One more question, would you consider putting me in your will? I would see to it this fine collection of tools would be respected and used, maybe even to help teach others.
