Matt Todd Posted February 5, 2015 Share Posted February 5, 2015 (edited) So, since acquiring quality high grade blacksmith coal is getting to be more and more a pain I decided to build a gas forge. The forge is built, and now I am working on the burners. The burner assemblies are made, except for the flare on the ends. My question is whether or not I really need to flare the end, or can I just leave it straight? The burners are 3/4" I.D. and I have the pipe that will slip over the end of the burner. But if I need to flare the end, I will need to heat the pipe and use a large drift to create the flare. I would rather just put the larger pipe over the end and be done with it. But if need be I will flare the end. Also, I'm super paranoid about blowing up and catching on fire. So, if you have any safety tips and issues to look out for so I don't blow up and burn to death that would be cool.

Bob Hewitt Posted February 5, 2015 Share Posted February 5, 2015 I've built burners with and without flares and, in my opinion, flares don't make any difference. As for safety, don't forget to fit an inline shut off valve somewhere near the burner for quick access and just work with common sense, in other words, don't do anything bloody silly! Check out as many other burner designs and setups as you can find and learn from them, they're all pretty much the same thing so if yours conforms to the universal basic design you won't go far wrong!

Jerrod Miller Posted February 5, 2015 Share Posted February 5, 2015 I went with straight pipe connected to the forge body (steel pipe), then flared the refractory around the inlet. If you're running a venturi, I would highly recommend a variable pressure regulator and a needle valve (in addition to your 1/4 turn shutoff valve) near the forge for control. Can't speak to blown forges for the pressure needs, but the needle valve I know is good to have. Keep a spray bottle with soapy water on hand at all times and spray your connections to check for gas leaks. If you're inside, get a carbon monoxide detector.
