Your roundhouse looks great! I was in the same boat about painting the castings but overcame and painted away! bought mine about 2007 or 8. just one question. what degree did you set your tracks into the roundhouse. I laid mine out on a big sheet of cardboard. I've started at 9 degrees but that seems really close together.


Mike - My turntable pit is 13.750” in diameter.  The front wall of the roundhouse is set back 18” from the center of the turntable bridge.  The original roundhouse kit called for a 30” setback but I didn’t have a big enough room for that so I spread the rear wall to bring it closer.  My turntable is operated with an Arduino controlled stepper motor so instead of using degrees I use steps.  It worked out to exactly 1” center-to-center separation of the tracks at the pit wall (30 full steps) which left just enough space between adjacent tracks so the rails don’t touch at the pit wall.  Available space for the roundhouse was the determining factor for me and having to spread the rear wall lead me to major modifications on the original kit which resulted in this thread.  There’s more info on the space issues and calculations involved in my layout thread “On30 in a small room”
