So I had an EPS Epoxy customer request a Incide blank this time around.
If anybody does not know what these are, here’s their discription,
Its not about the foam, its about what’s INCIDE…
A high tech blank with a carbon interior part that gives the shaper and ultimately the surfer infinite control over the flex of the surfboard. Think of a snowboard INCIDE a surfboard: All the magic and flex of your favorite board with faster recoil that lasts.
I should mention they are distributed by US Blanks.
So I shaped it up. (By hand of course). No stringer. Actually shape quite easy as there is no center stringer to slow you down.
Flex feels very much as a wooden stringer.
Finished weight feels good. Approx. 6lbs. I did use a 6/4 deck.
Here is something on youtube with the designer going into the thoughts behind it. It is also cool cause you can fast forward to around 10:30 and they show the carbon fiber center part. I would be curious if someone has tried something similar in the sense of putting a piece of wood sideways in the center and somehow gluing two pieces of foam around it, i.e. like a sideways stringer.
For a select group of talented surfers, pros and elite amatures, there is definately merit to this concept. The rest don’t surf well enough or with enough power to load and unload the flex of a board and even if they did they wouldn’t know what to do with the flex. I would also think that these elite surfers would need to go through quite a few boards to find the best flex for their style of surfing and type of waves being ridden as every rider and type of conditions would need a different shape and flex pattern. Kind of like different shafts on golf clubs or different flexes on fishing rods.
There was a company back in the 60s that marketed a board with what they termed a “transverse stringer”. It was a layer of wood that was horizontal in orientation, rather than vertical. In other words, it ran rail to rail. I believe they were popouts, though. If I happen to come across an ad I will scan and post.
The more I think about it definitely hard to figure out how to do a transverse stringer, short of doing what the Incide guys are doing. I did find another site where they were replacing wood stringers with composite cloth, which looked neat too, but same idea as wood stringer. Granted I I would love to get my hands on one of your boards with one of those agave stringers!
Cool post Keith, I could see pulling up to a break, looking at the surf and saying, I think I will use my 3 iron, or on a small day, how about a pitching wedge:)
Nice board lavarat, I like the repeatability part.
I make my blanks with composite springer inserted in foam. Allow me to design dynamic flex of my eps/epoxy board and keep durability. I test compsand, with wood, foam, both, but they are to long end expensive to build, often too stiff and too hard. My best boards were stringerless eps epoxy but they buckle. So i work to keep this feel but with buckling résistance. I started with all kind of reinforcement and i find an efficient solution to use springer in core for longitudinal strengh and dynamic flex with flexible tough skin for protection. It´s still in développement but in progress…
