Hi
Lads
Some pictures of my early "furnace torch"
I found the "flare" is the most important part of the torch
I used a 0.8 MM mig tip as a jet
Running on up to 30 PSI propane to get a high gas speed

vtsteam:
A bazooka! Nice big burner, john. I Imagine you did some melts with that one!

Hi
Thanks for the welcome, vtsteam.

The picture was taken before the modification on the turbulance slots.
Wich have made a big improvement.

Now it is a shorter, brush like flame.
The flame seems to hug the heated object more.

As far as your brazing question goes, the answer is no.
That would be streching things too far, for propane/air I think.
Nitrogen content in air, too much of a heat-sink.

mattinker answered your other question about M. Porter.
Have not read the book, but a lot of his info on the net.
Proffesor Google got his name.

Regards.
