Compressed Air/ Propane Burner

Hi Guys
               I was impressed with Ironman's propane burner, back in his October post. I decided that this burner was something I must have. I had aquired a small compressor a couple of years ago and never really used it. Rated at 2bar it would probably been capable of running a small engine.

Meldonmech:
I next needed an old oxy/acetylene torch to modify, and had to wait some time before  one became available on ebay at the right price, not wanting to spend too much on some thing experimental.

Meldonmech:
I started to look for some tubing and managed to find some 35mm diameter.  A small billet was then turned to fit in the back, this was threaded 1/2 inch BSF.

I remember in our "metalwork" classroom, there was a town gas and compressed air torch that I used to braze the handle on to a screwdriver that I made. The nice thing about propane is that the pressure is high enough to create a "venturi" effect acelerating the air flow. Town gas isn't under sufficient pressure to do this. The compressor would get around this problem!

A couple of passing thoughts, regards, Matthew.

Meldonmech:
A nozzle was made to screw into the torch 1/4 inch BSF, and  1/2inch BSF into the flame tube. A 1.5 mm hole was drilled for the jet.
