the rafters into place, creating a single unit. Scrap 1/32” stockwas glued into the interior corners of the roof above the spanningbeams to stabilize the corners. Lead weights were Goo’dthere, as well, to hold the entire assembly down and to maintainits shape. The entire roof and skylight roof was gap-sheathedwith HO 2” x 20” lumber, leaving a gap for that stove pipethat originates all the way from the first floor (Photo 7a,b). TheEast and West ends of the main roof and the skylight roof wereclosed in with board-and-batten made from individual HO 1” x24” and 2 x 4 boards (Photo 8).8lateral beams. The North and South skylight walls were thenclosed up with HO 1” x 16” clapboarding, with the same kickoutboard as before (Photo 10). Corner trim of HO 1” x 10”stock was added and the windows were then trimmed out withO Scale 1 x 3 lumber.Finally, the East gable end of the Boiler House was alsoclosed with individual clapboards, just like the sides were finished.Having clapboard above the board-and-batten sidingseemed to provide additional contrast and interest to that end ofthe building.RoofingAll of the roofing was done with Builders in Scale metalribbed-seam roofing material. All of this material was pre-cut tofour-foot widths prior to gluing it down. The Boiler House roofwas done in two courses on each side, using eight-foot longsheets and fitted around the chimney (Photo 11). I used Goo to11The skylight windows, made from the same castings ofunknown origin that were modified for the boiler house, wereassembled into a long unit. I pre-assembled these as framedunits for installation of one window unit between each of therafter assembles. I first made the 2 x 4 side-support framing foreach window. These were glued to each window casting, aftereach window had previously had a 2 x 4 glued to the top andbottom of the casting and a support 2 x 4 added to each side.These units were then painted with two coats of Polly S AgedWhite, and glazed with microscope cover-slip glass (Photo 9).After drying, these assemblies were individually fitted and gluedin place, centered into the openings created by the rafters and910secure this, which worked very well to hold this material down.With the seams cleanly overlapping, I worked left-to-right startingfrom the bottom corner of the roof, leaving a small overhang.The seal to the exterior East wall of the main building was doneusing this same roofing material. The seams lined up the nextcourse, as I had tested fitted the arrangement of two coursescovering this roof, with reasonable overlap top-to-bottom, andwith the top of the second course ending at the peak. The peakwas sealed over using sections of just the standing rib, cut fromscrap roofing sections, with a small portion of the roofing left asflashing attached at each side. These pieces were very carefullyformed by hand to conform to the standing seams of the roofing,secured with Goo with small areas of overlap as well.The skylight roof was three courses on each side, usingfour-foot wide material, but here six-foot long sheets were used12 • O Scale Trains - Sept/Oct ’06
