@gunrunnerjohn @Tom Tee Thanks for the insights. I think I've seen some of Tom's clamping photos before. I have a few clamps but nothing like the assortment of Tom's. The work you guys do is a far cry from slapping plywood on a frame.
One last question, how do you handle the raised track sections that do not have the solid substructure? I was thinking about attaching a gusset either down the middle or along the sides of the roadbed to add stability (spline and spacer Wescott).
