The need of a small-ish 350 in³ single burner that can forge weld,maintain optimum forging temperatures and travel well sets the parameters for this project, lets see what Mr. Murphy can do to discourage me , shall we? First, you gotta have a flame. finished, more or less, two Frosty burners and fired them off. One is as smooth as the xxxxxxxxxxxxxxxxx and the other is a bit ragged. I suspect that the gas tip is slightly out of alignment and I think I can correct that problem. I used Klutch .035 mig tips as they will work in my machine as well, they are only 3/4" long rather than the 1" twecos . I wish I did not have to use quite so many fittings to get what I wanted but if I make the adjustment bolt a bit shorter it won't be quite so extended, a jam nut rather than a regular 1/2-13 will free up some room as well. I can probably take off an inch give or take. this arrangement makes it pretty easy to tune on the fly the 3/4" couplings have been internally tapered at 5° and it does seem to have a positive effect on flame. Tried it from 6 to 15 PSIG with a stable flame throughout. I am surprised at how easy this was, I believe that with all the parts on the bench, even with all the machine time I could build 4 of these in less than an hour and a half. Not I need some malleable couplings that can be welded to the skin for the pyrometer and something suitable size to hold the burner in place, strangely enough not something available at the big box store. Any critique on the flame geometry? I figure the real proof is in the forge. I am impressed by the amount of heat these things deliver. Wow! Now for a box to put one in.
