For those of you who weren’t in diapers when this commercial aired, North American Paper Co. did an ad where Tom Morey made a cardboard surfboard for the commercial. It was ridden at Makaha, Tom had done several for the piece, the successful model was waxed and the “end grain” of the cardboard sealed with silicone.
May I suggest a duct tape lam on the bottom, with cutlaps for the clark box board? Cardboard and ductape would flow quite nicely, it would add a little weight I guess, and bonding to the back of the tape might be an issue… so you could actually just do the tape outside the glass
cut out about 150 rocker templates from the corrugated cardboard and seal them with acrylic sealer then glue them up 50 a bunch to form your rail bands and center stringer…
now cut up the outline from another flat sheet and coat with sealer them epoxy it to the stringers with a little glass tape…
fill the enterior with as many rice krispie bars that can fit in between all the rocker supports and sand her down smooth.
now gorilla glue on your selaed cardboard top piece and glass the whole thing in 10oz volan
take her out and ride you cardboard rice krispie cake special to the delight of the three elves hell I’d even lam the fronts of the all the boxes of rice krispies you’ll need to use over the sealed card board as a indicator of how many boxes it took to do it…
I’m excited to see those pics … I read this post last week and have checked back often to see if you had put the pics up of your tests. I’ve been spreading the word that someone was going to build a RiceCrispy board. When do you think you’ll get those pics.
