Yeah, you guys have hit on the one problem of a BB or CC Inferno. Ya gotta have something under the stove.

I'm thinking along the lines of a small aluminum pan with a piece of 1/8" plywood painted with engine enamel beneath the pan, probably screwed to the pan so that the screw heads in the pan would keep the bottom of the CC Inferno from sliding.

And perhaps two "shepherd's crook" style aluminum tent stakes to keep the base pan stable on the snow. The crook would fit over the edge of the little pan on each side.

Whaddya think?

UPDATE:
Rick, The CC's Inferno comes W/a 2-piece metal disc to protect the ground. I'd hope the aluminum pan with the plywood screwed to the bottom can replace the CC disc and hopefully not burn the plywood. I'd have to test it to see.
