At my cabinet shop we sometimes use a multilayer product called "Chinese birch." But we only use it for nailers and toe boards because it goes every which way when it comes off the saw--not very stable at all. For things we want to stay nice and straight, such as layout frames, we use a paint grade maple or birch veneer on a domestic (USA) core (usually fir), 3/4 inch thick. It's around $40 a sheet here, and the big box stores don't have it. Places that sell to cabinet shops do; it will be called D3 domestic maple, or something similar. Also some places carry a South American pine plywood called Arauco or somesuch, which a little better than the Chinese, but not nearly as nice as the maple. I would steer clear of US southern yellow pine, however.

Then I'll use Plaster cloth for all of my scenery areas. I'm talking about the card board that you see in furniture boxes used as side protection. That is all I have set under my track now. I have had to shim under the track in some areas but it is holding up for my 4X 6 small layout.

Much of the wood in his layout had been used in prior layout construction. I suspect that the fairly rapid change from mild to very cold winter weather and increased use of heat are causing greater problems than when the change is more gradual. Pieter E.

So, we have to deal with humidity as high as 80% and as low as 30% indoors, depending upon the season. the price of living in the Sunny Southland...
