floor using wedge anchors. I had 2”x2” aluminum angles made
for the framework corners. I did need to have the horizontal

1×3 pine was attached to the horizontal members using self

The risers are made from ¾” furniture grade pinewood. I cut
dadoes at 4” intervals, then ripped the boards into ¾” strips to
accept the helix roadbed. The track was glued to the roadbed
