[TheForge] Gas forges

[Michael H. Murphy]

One of the problems I've run into using brick instead of wool for the
insulation is that the bricks act like a heat sink, and it takes a while for
the forge to heat up -- and even longer to cool down.  I have not tried the
light-weight bricks, and I imagine the "heat sink" effect would be less with
them.  I've seen the light-weight bricks used as doors on a couple of
forges, and they didn't seem to hold up too well.

I've used Larry Zoeller's sidearm burner design for a couple of years now,
and I'm real happy with them.  I just saw a picture of the Mike
Porter-designed burner that Larry built.  I'm waiting to hear what he has to
say about the performance.  I'm working on my own copy, but it's going to
take a while.  It's quite a piece of engineering.
