I have been fascinated with model railroads my whole life and I think it is time to try making one of my own.
My problem is that I have essentially no woodworking skills and the thought of constructing the kind of benchwork I've been reading about is just too daunting. I need a way to create a tabletop for my trains that I can put together quickly and easily. I might try learning basic carpentry later, but I can't start off with it.
One suggestion I've read was gluing 2" of extruded polystyrene to a piece of plywood, then putting the whole thing on saw horses. Aside from only being able to find polystyrene in 1/2" thickness, this would seem a good solution for me. How well would this approach work? Should I glue 4 boards together to get 2 inches, or is half an inch sufficient?
