Compressed Air Propane Torches
catceefer:
For anyone interested, here is a picture and video of my compressed air - propane torch. I followed the dimensions given by "Ironman", although the jet is not set as far back in the throat. I need to sort out some new hoses and a connector to the compressor as it leaks badly, but I am really pleased with the overall result.
Thank you for the help.
Regards,
James.

James, seems the video is private.....?
Were you able to braze with it?
catceefer:
The video should be public now. I have not tried brazing with it yet, mainly because the airline leaks too much to keep running for more a minute of so, but I shall try over the weekend and update this post.

UPDATE
I have now. tried the torch out in practice and it brazes well. I tested it on the head of the dragon, on which my other torches only just work after a very long time heating. This new one achieves a better result within a very short period. The flame is a bit wild and I will play to see whether I can make it more focused. I may bend a sleeve up to go over the tube so that I can slide it up and down and vary the effective length.
Regards,
James.

I tried using a standard propane torch burner. Covered the air holes with tape and taped it onto the torch handle for a quick and dirty test. It gives a very nice controllable and hot flame. Not finicky at all.
As a test, I heated a slug of steel, 7/8" diameter, 1" long with a 3/8" hole running lengthwise. Using about 10 psi of propane and air, it rather quickly uniformally heated to a (almost) bright red. Appears to be on a par with the Bullfinch torch.
I also tried using a rosebud burner. Not as "nice", probably due to design differences, but considerably hotter.
It worked well enough that I'm going to make a proper adaptor and use them as my everyday source of intense heat.

Forgot to mention that I removed the orifice from the burners.
