CARDBOARD SURFBOARDS
or, Cross-sectional Notched Rib Assembly for Aquatic Sliding Boards

I'm building hollow, cardboard core surfboards. Cardboard, seriously. These are ridable prototypes for a new approach to building boards out of interlocking cross-sectional ribs cut from sheet materials.

Korduroy Interview

Watch me put a 10-foot surfboard in the back seat of a Volkswagen. Korduroy.tv came by to see some core kit production and ask a few questions. Here's the interview.

Fins
April 2010
Fin Tool Path

I've been developing a system to make fast CNC tool paths for cutting fins and fin molds. This video represents two weeks of work, through 656 frames of test output, in two minutes. The photo above is the first test cut.

Kit Builds

Starting to get some feedback and photos from the first few kit builds.

Make Magazine
August 2009
Make Magazine Feature

Page 20 of volume 19 of Make magazine had a good article about this project with a couple backlit board photos taken at the Maker Faire in May. The issue also had a good, several-page feature on how to make an EPS-epoxy-bamboo cloth surfboard. The rest was DIY robots and a big, smooth-sailing catamaran. Here's page 20.

Hot Curl Wet

Hot Curl Wet

Adrien is getting the hot curl wired in far-northern California. More photo evidence is likely on the way. For now we have these board glam shots and one hazy action shot: cold water hot curl

Fish Two

Had to try this again. Brought the weight down some, and got a smoother surface and smoother rails despite the simpler core pattern. slides
background

After riding the same 8'6" Robert August board for 13 years, I found it had developed a lively flex zone somewhere near the middle, around the cracked and swollen stringer. It was time to strip the wax and send the board into wall-hanging retirement, but I couldn't afford a new board to replace it. Why not build my own? Could I do that for a couple hundred? I didn't want to work with foam. What about a hollow wood board? Hmm... (continued)

Core Kits
    Not taking kit orders right now. Working on better, faster way to produce them.
    In the meantime, if you have access to multiple laser cutters, it might be worth your time to cut kits for me. email me:
