cardboard surfboard

I found this on another website here is the adress sheldrake.net/cardboards/build/

well. That’s pretty cool. Turned out a lot better than my attempt to make a blank out of Rice Krispies, that’s for sure.

tom morey(Y) already did the defintive cardboard surfboard back in the 60’s which was reported in surfers journal in vol. 2 or 3…i remember seeing the tv commerical it was made for , very cool

nat young made a cardboard cored board back in the 70’s glassed with epoxy. He rode it and enjoyed it, but it got a hole in it and sunk in the first session.

I’d think that with a properly molded skin it would work. If lightweight EPS is a suitable core, an engineered cardboard honeycomb should work OK. Bead and cove wood strips, balsa sheet, or plain high density foam sandwiched between glass and resin all make for a pretty stiff skin. The engineered honeycomb cardboard looks more supportive overall than a framework with greater spacing between the ribs/bulkheads(?) of more traditional framed hollows.

When I saw the cellophane on the rocker bed, I thought of Daklaw’s first compsand where he used mylar release film and got a great finish right off the vacuum. http://www.swaylocks.com/forum/gforum.cgi?post=275960

To be fair, Karl Pope had 99% of this stuff figured out a long time ago, I.E. how to manufacture a solid leakproof skin to cover a honeycomb framework. IMO, the aluminum honeycomb boards he built were far ahead of their time.

On these, as with any hollow surfboard, a little leak can present a big problem.

It was for a Boise-Casscade commercial during (I think) Neil Armstrong’s moonwalk. They only showed the spot once.

This was a long time ago, and my memory is slipping, but I seem to remember that they built around seven boards for the commercial. All of them ended up sinking. The one that made the shot worked great for one wave, then Tom took off, pearled, came up, and never saw the board again.

I also think it was during that time that Tom came up with the idea of using silicone to repair dings. Surfer (again I think) ran an article about how to use an ice cube to shape the ding repair… “the only things silicone don’t stick to are cured silicone and water”

Yes, everything has been done before.

I once tried to build a board out of dried mushrooms. Looked like a brown/grey chunk of old dish rags in the racks on my car. The dang shape kept changing when I got it even near the water. Never solved the return flex problem. I gave up when I found out the French had done the same thing a few years earlier. I think the key was to use a more buttery resin. Less fish eye in the hot coat.

I’m working with rolls of toilet paper now. Solves the brown/gray color problem if you use virgin material. As soon as I solve the sealing problem (spackle ain’t cutting it) I’ll post.

Greg…Mushroom board… Classic.

Mad caps or just some sort of cubenisis?

…I think that cardboard impregnated with resin is heavier than light PS with spackle…

I think you are right.
