Layout Construction–November 2010

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.
