@AmFlyer posted:Felt would work great. What I bent was only 1/2" thick in the plane of the bend. It varied from 1" to 5" tall. Sharpest bend radius was 25". The layout is on edge in my garage for 2 years, nothing fell off. My Christmas layouts, with one exception have been too small for grades.
Screws or nails through the plastic roadbed into the plywood base will increase noise unless Gilbert track in rubber roadbed is used.
Let me see if I got this right. I understand the ½” bend and gluing two pieces together to match the radius, centerline I imagine. Then you take a 2” wide piece and glue that horizontally on top. So with the 2” flat piece, is it cut to the radius? S-Trax is a bit wider that 2”, what happens at the edges?
I’m warming to the ‘spline’ approach for forming the grades in the sub-roadbed. I think I would make it more like 4” wide, and use spacers, again similar to spline sub-roadbed. The problem I have is taking it down and storing it. 29” curves take a lot of room.
Thanks for some interesting ideas,
