Spiral Helix Model Train Layout

Spiral Helix Model Train Layout. Building a spiral helix model train layout can be difficult because of the curvature of the spiral that holds the helix track in place. Tools such as hot melt glue, nails, ties and solder rail joiners will help make it easier to build this type of track. One of the more difficult points is to make it smooth and ...

Help with Conical Helix

 · you can do conical helix with arcs when you segment the spiral, a full pitch or revolution is two arcs combined, then you have moved 1 pitch in the Z direction, so if pitch is 2mm, first arc goes from Z0 to Z1 and second arc goes from Z1 to Z2. 14 / 2.2 = 6.36 revolutions, or 6 full revolutions (12 arcs) and a last 0.36 revolution.

Conical helix

The conical helix can be defined as a helixtraced on a cone of revolution(i.e. a curve forming a constant angle with respect to the axis of the cone), or a rhumb lineof this cone (i.e. a curve forming a constant angle with the meridians); it is not a geodesicof the cone. In concrete terms, we get a conical helix when we trace a path with constant ...

How can I design and build a helix?

A helix used for model railroading need not be a circular spiral. Many years ago, layout designer Don Mitchell of San Diego asked if there was a way to design a "Bathtub Helix" in 3rd PlanIt. Don''s non-circular helix was a new concept to me that came up again recently while working with Alastair Brown of Scotland and a track plan originally designed by Bob Sprague.
