I have a Ross Turntable on my layout. I thought it wouldn't be a problem aligning the tracks with the bridge, so I did not opt for the indexing kit. The reality turned out to be aligning the tracks with the bridge on the far side of the turntable was a problem. To solve the problem I mounted a mirror to the basement ceiling over the turntable giving me an excellent view of the entire turntable and making the alignment of the tracks fun to do.
