[TheForge] propane forge proportions

[Steve Smith]

My first forge was 12x18" outside, with 2" insulation and a single 
burner similar to what you describe, Jacques. It worked ok; more scale 
than it should have had (which I could probably have fixed now), and 
noisier than a naturally aspriated forge. Anyway, my point is that you 
probably have enough burner if you brick up both ends, just leaving a 
gap for you work.

I think this is a good size for a single forge. It is long enough for 
twists, and big enough for most work without being so huge it consumes 
too much gas and takes forever to heat. All relative, of course.

I currently use two forges, both with 2" insulation. One is about 11x15" 
outside with one burner. The other is 14x24" with three burners (all 
simple Reil burners). I use the little one more than the big one.
