Really enjoying shaping more Kneeboards. Done a few for some people here. Been doing some studying of George Greenough's stuff lately. Love educating myself & doing some homework. I pride myself in being capable of handshaping any surf riding vehicle. Being a fan of flex, got me to thinking of incorporating one of my stringer designs to kneeboards.
Seeing some good photo's of his Velo shapes, (Of which I have an actual Greenough template) and how his boards flex, got me thinking. People who surfed with George described his boards as bending or warping to fit the curve of the turn. Good stuff. Now I understand how such flat tail rockers were turning so well.
We all know boards flex. They need to. Too much is bad. Too little is bad. What if we could control it?
Flex is a design concept not talked about in the surfing world. Talk to most shapers about flex, and they get a puzzled look on their face. We've all seen end to end centre stringers (Linear flex) the standard for 50 years. Parabolic stringers out on the rail produce a "Springy" rail flex. Allows for the rail to be stiffer and then return to its original shape.
What if we could have both?
Torsion flex is new to the surfboard world. Based on the stored energy of torsional flex. I developed this stringer system a few years ago. Basically, it's a central stringer which is split at a certain point and curved outward to the rails. For stand-up surfers, it ends directly under rear foot. leaving the remainder of the tail to flex because it's stringer-less. I'm thinking further up for Kneeboards. Allowing more area for flexing tails.
The possibilities are endless. Maybe in conjunction with a concave deck. (Which I've done on one Kneeboard). I've also done some special glassing configurations with staggered fiberglass to allow the tail to flex.
One thing I like about you Kneeboard guys (of which I have joined as well) , is the hunger for innovation. That keeps me going.
I truly think George is/was onto something. This may be a modern twist on 40+ years of surfing evolution.
What do you guys think?
Anybody interested? I can be reached through my website or PM me here.
I'm going to offer this stringer configuration free of charge to anyone here on this website (KSUSA) to get this ball rolling. I'm Psyched on doing this. This is a $100 value as I have to not only have added width to my blanks, but also cut and glue these stringers in myself.
