There's sufficient latitude in the N-scale Unitrack rail joiners (19" and 28"R only) to achieve graceful, flex-track-like curves,...
For radii over 15", you'll need an additional series of bolts. Position them on the inside of each helix section, midway between the ends (so...
Determine the grade as you position the lowest level. For a grade of approximately 2.5% and a radius of 15 inches, I elevated each level 0.5"...
The various levels of the Gleiswendel are elevated by means of five 36"-long 1/4th inch bolts. I had intended originally to supplement these...
My approach is a simplified version of Rainer's. Instead of a two-ply system, I rely on Unitrack to even out small disparities in elevation, etc....
These photographs recount the construction of a helix for my Utah Division layout (N scale). Using a simplified version of a plan developed by a...
Here's the progress on my new layout. It looks like everything is going to fit.
