Thanks for the info TT2.
A chunk of EPP 24"X36" should be big enough for a couple of sloap soarers. That is the biggest piece of EPP that I've heard of yet.

Do you have any info on cutting EPP? I've cut other types of foam but have never used a hot wire on EPP. What temperature range should be used, in comparison to blue or styrene foam?

Thanks!
Chris
