Nick-
We would use acrylic plastic for the boards, most likely 1/16" thick. It can be laser scored or scribed at intervals to represent the individual panels and to locate where the red and blue lines would be painted and then masked (there would be a total of 3 colors). Then we would take 1/16" thick styrene or acrylic tube in the correct diameter to create the corners. A bit of a challenge since you have to mount the tube on a sliding table so that when you run it through the table saw up against the fence it stays secure and safe. What diameter are your corners? Once all of the pieces are cut, you could get real fancy and use styrene strip to simulate the framing on the back of the boards. What is the overall length by width of the rink?
