[TheForge] A challenge to Harry

[Kathy]

Successfully heating such a large surface (even heat, without oxidizing of
parts) might best be accomplished by drilling multiple holes in a mullite kiln
shelf, placing it on the overhead surface of a clamshell type (opening) forge,
rather than on its bottom shelf, and feeding a fan-blown air/gas mixture into an
overhead space above the shelf; thus, turning it into one giant ribbon burner. I
would use Kastolite 3000 to form the sides and top of the ribbon burner's
combustion chamber. The lower half of the forge could be made with 3" of ceramic
fiber under another kiln shelf (no holes), or Kastolite 3000. Since this is
quite a departure from usual clamshell forges, it should probably be renamed;
how about calling it a "Purse Forge"?

Hey Jerry,

As to how I would fire the larger forge? If I hang enough propane 
burners on it to make it look like a nuclear device that should probably 
do it right? Ok, that might be a little excessive. But just the same, 
multiple propane burners to make a larger hot spot. 40" may be too much 
and that may get trimmed down. I haven't made any headway on the little 
one yet so plans on the bigger one are ephemeral at best.

Still living at work, Harry
