Helix Construction
The next step in construction was to complete the helix to the top level. After cutting the circle for each level, construction continued with drilling holes for 1/4” threaded rods. These rods will allow the adjustment of each level to gain the proper height in each turn of the helix. The 1/4” particle board turn is held in place with a washer and nut from both the top and bottom.
To make the transition from the helix to the upper level easier, I applied roadbed to the last piece. This piece was lowered to the level of the previous curve. By adjusting the nuts this allowed a smooth continuation of the track surface.
Here is a video of the test run of the helix.
