In RMC at least a year or more ago there was an article from a guy using poly-iso (sp) roof insulation board. I have used the one inch thick stuff on a museum display and think it would work very good for a Free-mo set up. You would want to frame it with something light weight with the 3/4" ends but I think it would work good. It sells for about $17 for a 4x8 sheet of one inch.

I plan to retire my current modules to the basement after next January's Springfield show, and I'm thinking of building new ones out of Gator foam board.

You might check the LID back issue list. He has built on HOn30 module (FYI: the top side of his module is being featured iin NG&SLG articles at present) that is very light (10 pounds at most). There were LDSIG articles recently too (in last 2-3 issues I'd say). Someone else referenced an On30 construction that looks interesting....But not gator foam: http://www.trainweb.org/nbrandn/standards.htm Other groups use Luan with, the Sippin Switch group out of NC has lightweight standards. Free-mo likes to have 5/8 or 3/4 birch ends. I'm not sure how that will go with gator foam...The thickness is to avoid warping...Your group may be able to accept a change, as thickness is not required with Gator foam or some other techniques. Good Luck, Dave K.
