Started working on my forge's twin burners this week. So far, everything is turning out great. I have not tested this design yet, but plan to do so soon. I started off by taking a close look at my TurboTorch tips that I use at work (Acetylene gas). Here's a picture of the TurboTorch tip (A11). I too extra notes on the brass section of the torch tip, where the gas begins to mix with air. The gas flows from the regulator into a small chamber, with a very tiny hole machined in it. This little hole sits just before the air intake, which is proportional to the overall diameter of the tip size. I know this because other air intake holes on smaller and larger TurboTorch tips that I have increase and decrease based on tip size (A5 vs A11 for example). Here's a picture of the air-intake holes. Here's a somewhat poor picture of the little hole inside the tip I'm talking about. Anyways, I started considering how I could make this into a larger burner with propane gas for my forge. After learning a bit about forge burners form various sources (mostly the black hole of the Internet where I lost most of my soul), I took a trip to the hardware store (Ferguson Plumbing Supply where I do most of my day-to-day business for work). I purchased a few 1/4 brass fittings, including a 1/4 to 3/8 90. I took the small 1/4 brass cap which I purchased (hex) and drilled a 1/16th hole dead center in the cap. I took a 12" black nipple (also purchased from Ferguson) and cut off the threads. I then proceeded to drill a lot (like, swiss cheese-lot) into the top of the nipple about 3" down. I tapped some set-screws into the side of the gas pipe to hold my reducing 90 (still to be determined if this is the best way to center the fuel hole in the burner). I slid a small piece of stainless steel pipe (one which fit nearly perfectly over the 3/4 gas nipple) up the pipe and used a screw to set it in place (to control air flow for tuning). This covered some of the holes that I drilled earlier on. Finally, I choose to use a small piece of stainless steel pipe which was flared out at the bottom of my burner. I connected it to the 3/4 gas nipple via a set screw as well. The 1/16 hole in the hex cap as seen through the mostly-completed burner. The first burner, and the soon-to-be burner. I need to test the first one before I make the second. Ok. Tell me what you think. People - I'm not looking for drama. The last few posts I've made here have been met with some ornery little kid crap. If you don't like the way I write, move on people. There's at least a few thousand personalities on this forum. You won't get along with everybody. Moving on, away from the drama, I would like some honest opinions. I've never built a forge or burner before. ________________________________________________________ That's it. Let me know how I'm doing. Be joyful. Be friendly. Live life to it's fullest, and have no regrets. I forgot to take a close up picture of the little holes I drilled in the 3/4" nipple. They are as evenly spaced as I could get them with no drill press (soon I'll have one of those too). Again, I modeled the air-intake after the holes on the turbo torch.
