I am ready to begin cutting the ribbon roadbed for my layout. I was going to cut it the width of the roadbed and build up with foam around the track as needed. After looking at a few pictures I found on the web, I noticed that others made their subroadbed wider.
Is there a reason why, Any suggestions??
Thanks

In the past, I used to leave extra plywood to attach the screen or plaster shell to. If you are going to build up with foam around the subroadbed, the extra width may not be necessary. OTOH, if you are using thin foam (1/2" or less), you might want the extra plywood as a support.
my thoughts, your choices...let us know how it works out.

You don't say what the roadbed material is, but I assume it'll be plywood of some sort. If it will be massively thick, you can make it quite narrow without worrying about the sponginess you will have if it is not supported a lot. I used 3" wide 1/2" plywood, supported every foot and a half or so on Tee-shaped risers. Given my druthers, next time I'll go for 3-1/2"wide. The scenery will be self-supporting with a flexible connection (likely caulking) to the subroad bed, thus hiding the gap. So far it looks solid enough...
Good luck, let us know how it turns out. George
