In my opinion this is the best, most accurate and easiest turntable and can be modified for On3 and S scale. Here is my turntable in operation with NY Railway Supply indexing and step motor. I converted and HO CMR turntable for my On3 layout. It is small but I was more interested in easy installation with very accurate and simple indexing.
