I'm trying to create a 2% incline using Lionel trestles (1/2" rise very 24"). This requires spacing well beyond the 10" inter-track connections that are typical for Lionel trestles. I imagine I will need to place either 1/8" or 1/4" substrate between the trestles for support.
Any suggestions on what material to use fro substrate?
How do I go about making a template to cut out the track radius?
Thanks for the help.
