Cutting foam inner for case

Bob Eager · 2007-04-04T21:19:21+00:00

I've just purchased a small clamshell type case for storing a portable disk drive, etc. Nothing fancy, just a plastic casing with a thick wodgeof foam shaped to fit each half.I've always had limited success cutting the foam in the past, but this is a bit former and looks to be OK if I use a nice sharp knife.However, there is one thick piece of foam in each half, rather than the two thinner ones I'm used to. So, how do I cut a neat rectangular hole in the foam, limiting it to (say) half the depth of the foam? (i.e. how do I do the horizontal cut?)I thought of slicing the foam in half horizontally, then cutting the hole in one half. But even doing that horizontal cut neatly is a puzzle.I have no sophisticated tools; is there some easy way that I've missed?Thanks

I guess it has to go very much lower than a domestic freezer, then. Liquid nitrogen, anyone?

Electric carving knife works well.
