Hello All
....I just joined and am enjoying reading the different posts submitted. Glad to be online with persons who are willing to go over and beyond what would be expected to be helpful.
I am a novice HO grandpa and am trying to setup some type of bilevel track layout for my grandson (and Me). My immediate question is..I have quite a lot of rubberized 1/8 inch thick material which are leftovers from a roofing job that my son just completed. He has some type of "instant" adhesion glue that he used to apply it onto the plywood roof sheeting on a shed roof. Does anyone have any experience using similiar material as a plywood subbase on their layout? Is the use of this material feasable in your opinion or am I heading in a bad direction? Guess it could just be used under the trackbed but I have enough to cover the entire 4X8 sheet of plywood??
Thanks for any help
