abrasive Posted February 2, 2010 Share Posted February 2, 2010 I'm re-working a forge I built many years ago. It's been great for general forging, but I want to start welding and it's just not hot enough here at altitude. (Salt Lake area) The forge body is 8" pipe, 17" long. Two layers of 1" Kaowool all the way around, and a piece of kiln shelf on the bottom. Net inside diameter is, taking into account the non-round shape, about 5.5". So we're looking at around 404 in3. I made a little movable wall out of satanite-and-itc100'd kaowool. Oh, and ITC-100 on the Kaowool, though that needs to be re-coated. Single 3/4 "Reil EZ burner dead center, i.e. 8.5" from each end at about 10:00 pointed in so the flame hits the wall and swirls. If I were doing this over, I'd place it closer to the front - that's where all the heat goes. The back stays pretty toasty. I am looking at two improvements: adding a second burner, Porter-type, and upgrading the old burner to a Porter-type. My burner holder is 1.5" pipe welded into the forge body. Really not looking to cut it off and move it. I am thinking of adding another burner between the existing burner and the front - maybe 4" OC from the existing burner. Is that too close? Can I go closer? I really don't want the additional burner right in my lap... Or should I bite the bullet and move them both? Or just weld up a new forge body - I think I have the cutoff from that 8" pipe around here somewhere... I've already plumbed ball valves for each burner, so I can run them individually. Same pressure to both, though. Any advice welcome! Thanks, Dave Quote Link to comment Share on other sites More sharing options...
