Using A Helix Design Tool

helix calculatorGary sent in this question for readers:

“I have now used a helix design tool, but need to know how to transfer it to a 4’x8′ sheet of plywood.
Any available conversion to a full size pattern?”

Here is a link to a free helix design tool.

    Attached: basic way to get the most sections out of a sheet of plywood.
    (Unless anyone knows better ?)
    Draw a line down the centre of the sheet, and use a suitable strip of wood with a nail in one end and two pencil holes in the other as a compass to draw the curves.

  • Don Jenningssays:

    Gary HI When you build == or as you are building the Helix == use threaded rod to support the sub road bed and track. The threaded rod ,if connected to the power buss under the table can be used to power each “level of track on the Helix. You will not need a lot of wire (either showing or hidden) to power the track. Besides threaded rod makes it easy toi adjust elevations on the Helix.

Use Tiny Railroad Micro Controllers

A micro controller is basically a small programmable computer device to help the model railroader “make things operate.” It is clever way to realistically replicate the movements, actions and functions you are likely to see on a full size railroad.
