Re: Wiring a Helix for DCC

John,  the expansion/contraction issue with any kind of wood is mostly related to the humidity of the environment, not so much on temperature.  Plywood should move a lot less than dimension lumber but is not immune to it.  I live in a semi-desert climate with large differences between summer and winter temperatures and therefore large swings in humidity.  My benchwork is all plywood and I still get issues with seasonal expansion and contraction.
