Nearly a year ago, the below was posted as my new workshop / Layout room. Well, the shop portion (half of a 22' x 22' garage addition) is complete and the layout has been initiated.
After reading nearly every tip regarding layouts here on this forum and also reviewing my track plan on this forum we did the following:
Found this fairly good quality 3/4" plywood at Home Depot for $28 each. It is quite clear and is made up of 7 ply's.
Because the room is located in the Adirondacks and is only heated during use, we see temperature swings of 130 degrees. Based on various comments here, the 3/4" plywood was strip cut to 4" widths for strength and stability.
I purchased 3/8" elevator bolts for legs and all the hardware required off the internet at very reasonable prices. Bulk is the only way to purchase hardware as the local availability will cost much, much more. I purchased all the Elevator Bolts, T-Nuts, 1/4" fasteners, Washers and Nuts for a total cost of $35. And delivery was 2 days. I am so glad I added adjustment feet, as the best of floors are not really level.
The entire layout is modular so it can be moved or sold at a later date. The modules are all well under 7' and all the legs are removable.
Now I am making up corrugated templates in preparation for laying track.
Thank you for looking... Tom
