DoubleDAZ posted:Thomas, my 5x8x11 “L” shaped layout will also be against 2 walls when I hopefully start construction in the spring. I plan on adding casters, so I should have mentioned it, but didn’t think you’d want to move something that big. Just make sure you buy some quality casters.
Hello Dave,
Each caster is rated at 300-lbs and there will be six of them so I should be OK. My plan is to make all the frames out of 1-1/4 x 1-1/4 x 3/16 aluminum architectural angle and the columns will be 1 x 2 x 3/16 aluminum rectangle tube. This frame will be really strong and still be light weight, and of course excluding the decking, foam, and Train equipment. I just completed the CAD drawing for the Frame but have not made a materials list yet. The angle only weights .519 pounds per foot, so a 20-ft joint weights in at only 10.38 pounds. I will try and finish the materials list by tomorrow and work up a total weight and will post it here. It will take a bit of time for the list because I will draw each piece showing all the dimensions and cuts and then label it. I sold my aluminum welder last year so I will have to have a shop do the welding and I will actually pre-cut and label each piece. Then they can fab it up from a "break down" drawing that I will supply. Thank you again for all your help, I am most satisfied with this Layout and cannot wait to get it completed.
