I'm real curious (after all this discussion) about what you decided
to do?

It was in one of my replies. After reading about the toxic fumes I'd get
from polyurethane, I suddenly remembered a hacksaw blade I have that
looks like it came from a bread slicing machine, and maybe it did.
Going to make a simple fixture to hold the blade under tension at the
required height, and oscillate the foam past the blade.
I'll post a few pictures to the Drop Box when I get back to fitting the
drawer for my micrometers.

I may yet make a hot wire cutter for some other project, but I don't
have many cuts to make, so the blade should do fine.

You WILL get a smoother cut with a hot wire.

A NIOSH mask solves the fumes problem nicely.
