Really hot here in Virginia the last few days. But, despite the heat, my buddy and I have been trying to get the old blue Dodge ready for a big car show next weekend. That didn't go so well. In trying to get it running right, we adjusted the carbureator and adjusted the timing. There was no happy medium between engine pinging and a massive fireball exploding out of the carburetor. So now I'm back inside in the cool of the basement, working on the layout.
A couple days ago I used latex caulk to attach the first three inches of foam on the layout expansion. Then I ran out of caulk before I could add the top half inch contoured layer (where applicable). I had to let that sit for 48 hours with piles of magazines weighing it down. In places where the foam had been shaped to form a slope and the edge of the foam was razor thin, it wouldn't always lay flat in place. I had some three inch deck screws lying around and screwed those through the foam to hold it down in those areas. It worked well, and when everything is smoothed over with a thin layer of light weight joint compound or hydocal, the screw heads will be permanantly hidden.
So, while that was drying, I used the section I had cut out for a sloped road as a template. I put the foam pieces on plastic "No Trespassing" signs, and marked the shape of the road (leaving some excess to be trimmed down later). I put the pieces back on the layout to verify it fit. It was only because the roadway sits below the surrounding land that I had to perform this step before making anything permanant. I needed those foam pieces under the road surface as a template before I attached that foam in place.
So now I have the top 1/2" layer of foam to caulk in place both where the town will sit and where the blue farm house will be. I will need to set the track back in place first so that I get the location perfect (I neglected to mark it before taking it all apart). Don't want that foam too close to the track.
Once those additional pieces of foam are in place, and dry, then I will use Woodland Scenics Hydrocal or a tub of lightweight joint compound to smooth everything over, and to hide any joints in the foam. Once that's done, paint to hide the foam and plaster surface, and then I'll be ready to permanantly attach the track and drill holes for wiring. After that, I'll have one little train to run around the one inside loop of the new expansion. At least something will be running while I turn my attention to the track and wiring on the rest of the big layout.
Now to go open a new tube of caulk...
