So I'm working on a propane forge build and I havent decided yet on the burner to use. I am familiar with some of the various designs out there on the net (EZ, sidearm, T Rex, Mongo, Guru, T-Bird), but I'm curious what you guys think. I'd like to try building one first before having to shell out the cash to buy one. I've seen the designs for the EZ but I've heard people say its an outdated design and others out perform it. What about the T-bird? http://anvilsandinkstudios.com/burner.html It seems the T-bird might be a good choice (based on some things I've read), but the design is for a 3/4" burner. Does it scale up to 1"? My forge design is based on a standard grill propane tank so I estimate my forge chamber volume to be ~500 cu in, suggesting 3/4" burners to be insufficient. So what do you guys think? Whats a decent choice for a venturi burner that I can build in the shop of sufficient size for a 500 cu in forge? Kek.
