[TheForge] Re: reducing fuel costs by improving forge efficiency.

[Ralph Sproul]

        Thanks Marc, I was wondering if you'd used stainless runners on the
bottom to hold things in place.
        I think I'd like to try a test lid with the blanket to see how it
distorts, holds up, etc.   Would you go with the same tank configuration -
or more of a barrel shape if you attempted this?  I'm thinking maybe the
curved end slugs of Kaowool would help hold up the rest of the blanket in
the lid.

        Why are you unhappy or questioning the refractory lid?  The problems
shaping the mix? cost?    I'm curious, as your last message seemed to
indicate working it was a bit of a problem.

Ralph
