Hi morphoist, if you are looking for a quick base board construction, go to my Camdale page, my module construction is simple.
I can build a module in a day 2 ft x 6 ft can stand on the module no problems.
I use 12 mm ply and 100 width for the sides and front, now I use straight ply very light to pick up is what I want.
Will have layout finished finished by April May celebrating 5 years in the forum.
