birds eye view of traverser This view shows the top, a fan with 6 tracks and the traverser pcb with the flextrack
below baseboard construction And this is the underside of a similar construction, during the installation. It also shows how the slot is constructed by predrilling a series of holes that are enlarged to a single curved slot. This is not the same traverser but a second one replacing the earlier made points at the other end of the fiddleyard.
