: Anybody have a good way to cut large slices of minicell - for example when
: cutting a wedge out of the bottom of a seat meant for a hardchine boat
: like the Chessapeake.

I have had a lot of success using an old electric carving knife. Granted this was on lower density foam, but I think it should work even better on minicell.
I hope you have one stashed in the basement like I do, or it's off to the garage sales again!
