Sector Table
The Fiddle Yard comprises a Sector Table, mounted in a rhomboid board. The table is 15″ overall (7.5″ radius). There are three tracks, which are energised via brass bolts, which also locate the tracks with the entrance track.
Some details of the pivot, which also provides the electrical common return to the tracks.
My apologies to any who have previously used the calculations below – I found an error in my Formula 3, and so have corrected, as of 1 May 2017.
I have described how I calculated the radius of the curved tracks here:

Very useful — sector tables are much easier to construct than traversers. Useful too if through running is required for continuous run.
