I am building a shuffleboard table and I need to come up with an inlay of some kind to designate the scoring lines. The top is made of solid maple and walnut. It is 1 1/2" thick and 20" wide. I'm concerned if I put a walnut inlay across the grain of the top it the inlay will not move as much as the top will with expansion and contaction. I also considered using brass or even just colored epoxy, but I still feel like I have the same problem. Am I just over thinking this? It appears from a Google search most are using a epoxy or plastic of some kind.
