: Does anybody know where I can get plans to build a snowboard?

At last

Hmm no I don't know where to get plans. But I made some small boards to my kids when they where small. 2x4mm ply glued together and with bended ends. The shape is easily estimated from some existing board. The biggest problem is the steel edge. you can use a steel sheet 1mm thick 20-30mm wide but here I am only guessing.
