one thing for sure.
if your bottom is sagging. (no jokes)
it is very important to prop it up.
a couple of hard brick in the center, under the kiln
works wonders.
never let it sag to that point.
prop it with brick.
i have seen wonderful old electric kilns sitting on concrete block
bases..with a piece of expanded metal holding it all together.
will last for years with support. it is just brick.

Mel and all,
I fired my first test fire on the 7 cuft Olympic gas Labor Day. When I opened it, there were cracks meandering all over the base. I only took it when cone 8 went down as it was firing way too uneven. I had to go research some more to find out how to fix it.
In reading Mel's post about putting hard bricks under the kilns bottom; I went and bought 9" hard bricks and 1" flat rectangular bricks. It is 11" from the cement pad bricks to the bottom of the kiln exterior.
My question is: In some spots there is about 1/4" gap before they meet. Does this gap need to be filled with ceramic fiber or shimmed in some way? I'm thinking the soft bricks will expand and still be supported by the hard bricks. Will it hold its load of furniture, shelving and pots without shifting up to cone 10?
