[TheForge] burners and other addictions

[Jerry Frost]

I don't have a viable opinion about the UK torch other than I found the 
article I read reasonable at the time, the test data was believable and the 
how and why preheating the propane worked made good sense. None of these 
really mean much as I don't have the article, URL, etc. to back it up.

As I recall though (he says going foreward anyway after admitting any 
opinion is based on geezerly memory) the preheated propane mixed much more 
easily with the incoming air. They claimed to be able to weld mild steel 
with their hand held air/propane torch.

The propane preheat circuits were really complicated so I didn't persue the 
idea which is partially why my memory of the process, results, etc. is 
vague. Basically I decided it wasn't worth attempting on a home made burner 
level.

Okay, burners are peripheral to your vision quest right now. I know how it 
is, I thought I'd lost my readers this morning and was pretty panicked till 
I remembered (geezerly memory <sigh>) where I'd set them.

So, good luck on vision enhancement, chapter shaping and all the rest.
