All 1/2 inch plywood. 1 inch batten of 1/2 plywood around edge on underneath side making the edge 1 inch thick. Back is two pieces of 1/2 inch plywood glued together with a step of 1 inch so the top piece turns upside down and screws to the bottom piece protecting the two pieces for transportation. The Timesaver is 31 inches by 6 1/2 feet. Why? That is what would fit in my 1997 GMC Astro Van. It fits easily in the bigger van. What else? HO cork roadbed two pieces side by side actually making 4 pieces side by side. First 2 come not quite cut all the way through to protect the beveled edge. That is the way it si put down. The I take another section divide it at the bevel and use it as the edge of the two pieces that aren’t seperated. I’ve done all my inside track this way and still very happy with it.
I have literally built this at the ECLSTS, the SELSTS and the GGRC’s shows. If you cut the basic frame at home we could assemble it there. I have a small miter box saw for cuts needed. I can dig out more old pictures if you want. Glue, air nailer and paint. I think this is will be the 7th year we have been at York and the second year at Perry. Having the layout there, really adds to the fun.
Also makes a good test for the new stuff people buy.
