Compressed Air Propane Torches
vtsteam:
Not quite sure what you're describing, Orange, any pics?
Orange Alpine:
Yes, I have pics, but for some reason the 'puter is not recognizing the camera card.
The burners/nozzles are old Turner propane torch items. The kind that screwed onto a short, bent tube that screwed into the valve body. I have found that the more modern nozzles that are integrated into the tube will not work at all. At least the Craftsman I have will not. Also, it seems the nozzles work best when taped directly to the acetylene torch handpiece. I bored a #5 welding tip out to .111" and screwed the nozzles onto it. It worked and I took some pics (that I can't get out of the camers), but I'd swear the results were inferior. More finicky and could not be pushed as hard. More testing is in order.
Here is a link to an image of the type of propane torch I used.

WOW, :bugeye: that would have to be the longest link I've ever seen. It worked though and good to see what you used.

Found a card reader that works!
Here is the torch in it's native habitat:
Nozzle modified and ready to go:
Going at full tilt:
Another nozzle, slightly different design, same size. This one seems to work the best:
Rosebud:
New design Craftsman integrated burner. A real lose for this application:
Did some more testing. Connected the nozzle to the Turner pipe, then taped to the torch handle. This gives .190" delivery pipe intead of the .111" of the welding tip. Then taped the nozzle directly to the acetylene torch and handle. I am convinced the direct connection gave a hotter, more controllable torch. I think it is due to slower gas velocity. Taping directly to the torch handle produces a small chamber, causing the gas velocity to drop, allowing more mix to get into the burner without blowing out the flame. But maybe not.

I think this is going to be my final effort. It is the nozzle that performed best, mounted on a #5 welding tip. The nut is a 5/16" tubing flare nut soldered on the tip. It had to be drilled out about .040" to fit the tip. The 5/16" flare fittings are 1/2" - 20, so I turned and threaded the Turner nozzle to match. It all worked out good. I will probably modify the rosebud nozzle so I'll have a "big" and "little" source of heat.
The nozzle is being pushed to its limit in this photo.
