Originally made as a presentation for the Trinity River Division for the NMRA, this video shows how I built my double helix for my N-scale layout.
Helix Specs:
1/2" cabinet grade plywood cut into 5-1/4" strips
Segments cut at 15-7/8" on long end
38" Total width of level
2.3% Grade
2.67" Total height between levels
2.2" 'Finger' clearance between levels
18.5" Elevation change
18-3/8" Radius outer loop, 17-5/8" Radius inner loop
Circle jig is calibrated for 1/4" bit so outer loop routed at 36" and inner loop routed at 33" with 3/4" bit to get the above radius.
Routing depth at 1/8"
51 pieces of Atlas Code 80 flex track mounted with ME medium rail spikes.
