[TheForge] Gas forge Question

[Justin Fellenz]

I did this with my first forge...the shell is about right, 18 guauge
sheet, but I lined the whole thing with 3" high reflect brick and
mortared the whole thing together. Doors are castable. The beast weight
like 300 lb and is no bigger than a whisper daddy inside. The mankel
blown three-burner manifold gets up to welding heat with 5 lb of
propane, but there are cold spots, oddly, under the burners themselves.
You cans ee the darker patches where the flame hits the florr of the
forge. I am thinking that maybe I have too much wind at the moment, and
that angling the manifold so the flame swirls would help....

The next one I make will be with inswool and this satanite stuff I've
been hearing so much about, inside a piece of tubing or a 30-lb propane
tank. Still heavy (like everything else in the shop) but convenient.
