Primarily the acrylic backer. I'm afraid that if I mount acrylic track directly to the wood , expansion/ contraction will effect mounting.The acrylic track turns hazy, the clear acrylic backer turns hazy, or both?
That's dumb... I should have thought of that. I was sitting here imagining hogging out .25" aluminum for custom track, never occurred to me to stack materials. Long day ahead I guess.I've done wood tracks before for a menu board. It was just a strip of 1/4 ply with another strip wider than it glued and brad nailed to it.
Hello Dale, Did you ever locate metal zip tracking?I know there is tons of acrylic changeable letter track made of clear acrylic. Does anyone know if there is any supplier who makes them from a metal? TIA.
