Thanks Lynn. The frame for the layout is made of all 1 x 3 KiwiPrime? select lumber, nice stuff. I have several lengths of SPAX screws that are also quite nice to work with. And my time is way far from being Valuable
What I don't have is plywood or any way of getting some here. The table is 1/2' wafer board an I hate it. The only flat product Menards (30 miles round trip) supplies in 2 x 8 sheets. They fit in my Nissan Sentra. Home Depot will rip plywood for you but that is a 90 mile round trip
I have plenty cross members, the wafer board is not glued, just minimally screwed to the frame. And the 1" foam is not glued but minimally screwed to the wafer board. Sounds strange but is solid enough. I could tear down the entire thing in less than 1 hour. So other than fighting the wafer board I am all set to put your suggestion into action!
I plan on setting up the Unitrack I have to see what I can accomplish in the area on a flat plain and then figuring out the vertical aspects. I am bad at software as well as having to physically visualize layouts without using my hands and moving the Unitrack around. Did that make any sense?
I will research open grid layout construction on you tube this week. Thanks again.
