To do what with ?Long time lurker here anyone tried this ?
If so how
flamefast torches used in forges wil run on propane with compressed air or north sea gas. heres one in use on the right along with oxyacet torch on the leftThe trucks that go around doing the white lines on the road use this setup.
Propane torch and road compressor providing the air.
It makes a flame hot enough to melt the line paint so it can be erased.
A place to look for ideas would be the brazing forges used in school D&T classes. They use natural gas and blown air, but the principle should be similar.
...can get metal just about red heat but would like a little more heat...
Good point will look into fire bricks as the flame fast new is a bit out of my price range and for what I need will do I think thanksYou may not need the air assist. Are you using a hearth and firebricks? They will concentrate and reflect the heat. Have a look at knifemaking ovens. They use a non-assisted propane burner but are very well insulated. The solution might not be to put more heat in but to prevent or reduce the heat you do have from escaping.
Yes will look into that alsothe post i put the heated part is packed round with fire bricks to contain the heat otherwise it is just lost if you want more heat you can just use a bigger burner nozzle on the propane torch
Does she make the things ?If money no object try HarrisFlamefast T2 & T4 Gas Torches

Why not make yourself a small propane forge,old gas bottles are idealThanks for taking the time to reply, want the set up to heat metal so I can work it - I restore old tools bill hooks etc I have a propane gas bottle and torch and can get metal just about red heat but would like a little more heat (I have a small compressor) not quite a forge but something near it - will have a look at the above - should of thought of searching myself !
We've still got one of those.Our brazing hearth at school was gas with blown air. The gas was town gas. It was the 60s, after all
Plenty of heat available.
