Steamtrains' 2010 Summer structure challenge entry

... You could also build pyramidically-shaped smoke collector hoods by cutting and assembling four triangular pieces - sheet styrene would work well. Make them with the opposite sides as identical pairs, with all mating edges the same length. Vary the lengths of the lower edges (again, in pairs) to create rectangular-bottomed pyramids or make all four triangles the same dimensions for a square-bottomed hood. The exhaust pipes through the roof can be round or square for either cone- or pyramid-shaped hoods. -- Wayne

Kool! I'll burn that info into the cranial hard drive for use when I get a bit farther down the tracks during the "Building a Layout in Southwest Florida" part of my model railroad experiences. But, alas, for now, it's back to the breakfast nook table and fabricating the shadowbox interior to my Challenge building.

I am looking forward to building the roundhouse, though. and being at 54" - 56" off the deck, all these little roundhouse/enginehouse interior tidbits are valuable information! Thanks to all for discussing them and their fabrication!
