Mike g, the flats are O gauge. They are alittle pricey but I think they are worth the price. They come on paper so I glued them to foamboard using 3M adhesive spray. Directions said not to use white glue.
Today I started playing with the new building flats. Adding the silos to the one flat and just placing the others along the wall to see what works. The PVC pipe I had left in shorter heights I put along a siding on another table. Also started to add washes to the walls of the machine shop. Looks like what I really wanted to do with the area left is difinately not going to work. So as they say.......back to the drawing board..Pics.....Paul 2
