I have been asked by a church group to build something like the tracks in the pix below. After shaping the plywood sides, I don't know if one would route a groove for the plywood track surface to slip into. I would assume one would use 1/8 in plywood for the track surface since that would flex a bit, but I don't know how to attach the two sides of each of the tracks and to make sure the tracks are strong. Anyone do something like this or know of some plans that I could adapt. Each track is supposed to be about eight feet long and about five inches wide. Any help would be appreciated.
