"which thickness of ply would you recommend for Mianne benchwork in a basement
environment? It is poured concrete with no water problems thankfully, but humidity
runs about 65 pct. in the summer. "
What kind of track and scenery will it have? Will the benchwork be covered with a continuous table top or will it be just narrow plywood roadbed under the tracks and plaster or foam elsewhere? Is there any wooden furniture or other items in there that give a clue to how wood does in there? .......DaveB
