Thanks guys, it was a fun afternoon, also very satisfying. I picked a couple projects and finished them. Good thing there are 10,000 more where that came from. The last day I took off was October 9th, almost up to two months straight.
Mike - That question has come up a few times over the years. It serves a number of purposes. In the case of multiple tracks, it provides perfect spacing. On curves, I screw down the material on the inside of the curve, and use it as a bending jig. Then I add a second layer that goes over the ends of the ties, and holds down the track. Of course it is only for areas that won't be seen.
Deuce - I'm a little embarrassed because that turntable and roundhouse are sitting on a 4x8. Humble beginnings. My first layout, off the floor, was on an old ping pong table. I'm glad to hear that you are benefiting from what I share here.
Arnold - Thanks, but it's not as pretty close up. It is better than when I first built it though, I redid the vertical supports last year, in order to increase clearance. I own a Big Boy, but it won't go on the layout. There are too many other areas where it won't clear. The Challenger is the biggest.
Mark - Thanks, of course the wife took it. There might be more pictures of me, but she rarely comes down anymore.
