Hey guys I want to make a practice board that I can use on a trampoline to work on various things. My initial idea was to take the trucks off a skateboard and just put some straps on it but I would expect that to damage the trampoline mat after prolonged use. So I thought maybe I could get some hard dense foam like a knee board is made out of and cut it into a skateboard shape. I figured something like that would be more suited for a trampoline. Does anyone know a better proven way to rig something like this up? Any help is great!
