I have a friend who built a nice big cabinet out of 3/4" plywood. Don't laugh---it worked great. He welded up a metal "grate" to rest the parts on, used an old peice of 1/8" plate for a "backsplash". He was able to put in a huge hinged door with a gasket---the door opens outward, and he hooked up an old shop vac for a 'dust evacuation" system, and the negative pressure it creates keeps the door tight shut when its being used.
