Thanks for the reply Matt. Man Burbank is a far drive. I live in San Pedro, 30 miles on google maps. Are you a member of the Angels Gate Hi-Railers? I have so many questions. Building my first model railroad. All my other layouts have been on the floor. I tried to stop by a couple times but it was closed.
Right now I have 1/2" plywood down. I was going to put a layer of foam down then the track on top. I want to be able to carve into the foam for scenery and layer the foam to make small hills/mountains nothing to big. The local home depot sells R-Max which is similar but it has a foil on both sides. I read other forums people say you can peel it off rather easily. Have you used the R-Max before?
Thanks,
Jason
Didn't know you were THAT local to us. I'm a Founding Member of AGHR. Been with the club over 20 years. We're there Saturdays from 10:00am to 4:00pm (running and sometimes wrecking trains) and Wednesdays from about 5:30pm to 8:00pm (usually tinkering with the layout). I won't be there this Saturday, but will be for the Open House on the 15th and 16th.
You can peel off the backing on R-Max and R-Tech foam. It's the expanded (bead) foam and can be used for track support with a sufficient base underneath. Use foam-compatible Liquid Nails for projects or carpenter's glue (pour and brush it) to glue it to plywood. For scenery purposes, it's fine. The pink/blue foam is what you want to use if you're trying to make lightweight modules with minimal sub-support or scenery that has to be taken up frequently. We mostly use expanded foam for our scenery and cover it with painted-on plaster and castings.
By the way, found another Home Depot in Anahiem Hills that supposedly has the Owens-Corning pink foam. I pass by that one on the way to the club (I live in San Bernardino). I'll check to see if they have it.
