Model Railroad BenchworkBenchwork ConstructionThe Birchardville Railroad benchwork is both L-girder and joist construction for the peninsulas and around-the-walls construction with joists on commercial 10 x 12 inch metal L brackets screwed to the wall studs on the east and south walls. These brackets also secure the wall ends of the peninsulas in place. The peninsulas have a leg structure with 3/8 inch diameter lag bolts in their lower end to allow for height adjustment, even though the basement floor is quite level, they allowed me to adjust for miss-calculations between the height of the peninsula sections and the L brackets on the walls. I made the L girders for the peninsulas from (nominal) 1 x 2 inch dimensional lumber edge glued to 3 inch wide strips cut from 3/4" plywood left over from a concrete forming job. Since the larger peninsula is 10 feet long, I spliced the girder sections during their fabrication so that the joints in the two girder pieces were two feet from the opposite ends of the girders. I thought I'd left enough room between the upper and lower levels of the layout, but found after I'd built the supports that with the 2 inch thick extruded styrofoam material, that I wanted more space between the decks. As a result, I set the joists (more 1 x 2 material) on their wide side. They're close together and not too long both between the L-girders and at the outside cantilever ends, so I don't expect bending under load. The extruded styrofoam material is glued with a construction adhesive designed for gluing styrofoam. When glued to the joists the whole thing is quite rigid. |
