[TheForge] Chip Bed Forge

[Chris Kilpatrick]

A lower combustion chamber makes much more sense, and I can see how it would allow for many options.  My next question involves top temp of the forge.  With a separate box below, even with good insulation, do you have a lower top temperature?

It is I who formed the blacksmith, 
who fans the flame into a fire and
fashions a weapon fit for it's work.
