[TheForge] On the table monday.

[Jerry Frost]

It might. I don't know how they work though. <grin> I'm 
planning on having a downdraft exhaust system in the 
shop and hope it'll handle the propane forge. I doubt 
this is what you're talking about though.

There are all kinds of solutions if dragon's breath is 
bad enough to be a problem. One of the up sides to 
using a gun burner system is their ease of tuning.

A naturally aspirated burner can be tuned for a mostly 
closed furnace but it gets thrown off if you want to 
run it open. An adjustable choke(s) may be enough to 
deal with it as can making the jet depth adjustable. It 
get's more complicated and touchy than a gun though.

A lot depends on how flexible the smith needs his forge 
to be, many folk do essentially the same thing most of 
the time and can tune the burner and leave it alone. 
Some folk do many different things and have to have 
either a really flexible forge or a number of forges. 
I'll probably fall into the latter but nothing is 
certain.

it ain't real.
