I have another topic I would like to hear some comment on. I'm building a layout I found on another forum. As suggested, I have a piece of 3/4" insulating foam mounted on a 36" door which I cut down to 60" for a 3 ft by 5 ft bench. Someone suggested using hot glue to mount the roadbed to the foam and to use CA to mount the track on the roadbed. I wonder what folks who know a whole lot more than I do think of this idea.
