A Twisted Curve

Referred to in the model train world as a Helix. In my spare time or lets say my hobby time I have been fabricating a helix for my HO train layout. My Helix will only rise 405 degrees. One and one quarter loop.

The base to my Helix was constructed out of scraps of 9 ply 12 mm plywood glued and biscuit jointed.

Yes, that's 16 clamps for glueing the risers and road bed.

This was todays progress. 180 degrees to go for a total rise of 5.350 inches. In scale terms that will be just over 38 feet.
