The 2'x6' recently built NOSS modules used 3/8" poplar for sides, 5/4 poplar
for ends, 1/4" luan ply dadoed into the sides and ends for subroadbed and a
couple of poplar 1x2's for stiffeners glued to the underside of the ply. If my
memory is correct they came in at 10 or 11 lbs before we added the 1/2 Homasote
roadbed which essentially doubled the weight. All wood and 10lbs at 2x6 feet
seemed pretty reasonable to me. The lesson learned involved the Homasote.
That stuff is really heavy. We just glued a 2x6 foot sheet on top. If i was
going to save weight I would cookie cutter the plywood and Homasote or use
another lighter roadbed product to begin with.
I would look to Gator Foam or Polyiso insulation board for ultra light modules
(say 5lbs at 2'x6'.) The stuff is structurally stiff enough you could use it
to build up your entire module. I would skip any wood product altogether and
clad the outside faces of the module with something like paper chipboard or mat
board. It's lighter then any wood product and would reasonably resist bumps
and dents.
