I spent some time on this last night and Im toying with the idea of using plexiglass for the whole thing. That way I can glue the boards to the "ice". Also the boards and glass are one piece that way. I made a form out of a 2x4 and used a heat gun to soften the plexiglass which worked pretty well. Still a lot of bugs to work out, though. I'll try to post more pics tonight.
