I looked at Dan's photo's of it. It looks very similar to the
white coated laminate carried at lumber companies. That sort of
makes sense as Trespa seems to be used for partitions and other
office type constructions.

Trespa is stringy lignous wood fibers put together with phenolic
resin. It is sort of a cheap version of Garolite XX which you can
find in the McMaster-Carr catalog. Garolite is ideal for
building something like the EDM and is commonly that yellowish
stuff used in electrical motors and generators and terminal
strips. Smells bad when hot too - like phenolic :-).

I think you are back to MDF really, but just a specialized kind
that uses better prepared wood fibers and phenolic resin. Might
be HDF not MDF.
