Hello all!
Coil Surfboards. That is still something else, INNIT?
Do you all think I can go and take the red pill online? Disect the Alien technology? I won’t take the blue one online for sure.
So Kirk, Mike or Brother… Id you don’t want that because you are still alive and building them, say it here. Otherwise I will do everything I can to find out how they are built.
Met vriendelijke groet,
Wouter Oosting
I’ve searched recently.
I can’t find an active site retailing Coil Surfboards.
Sure looks like they are out of business…
Second board trying to emulate the strength and liveliness of the Coil Surfboards. No Cordura was actually found in the core lamination. Bert Burger once suggested to spit, rub and burn any material you want to know more about. And it burned all right, just not the way Cordura does. So, 100% no cordura inside the core lamination. The outside, maybe, but polyester is cheaper and does the same thing as far as I can think of. In the picture you can also see the first try which worked only till ridge sanding time came around.
Something to think about. “ Veil”. Not the kind you buy at a fiberglass shop, but rather the same kind you use to make wedding veils and “tutu’s”. AKA “Tulle”.
From what i know, Cordura is a trademark for tissus build with many kind of fiber but mostly nylon wich is polyamide 6.6 .
Nylon have a high elongation to break wich give it a high toughness and abrasive strengh, but thanks to it’s low surface polarity, as most plastic fiber, a poor resin adhesion.
Some plastic fibers are build to be more resin compatible like kevlar, diolen, inegra, spectra (trademarks of polymer)… In open waves can work with right resin for toughness. PET grid too.
I only see one coil, grid tech, for a crease repair, not impressed by the tech. I find a good multiaxial glass fiber cork sandwich better in all aspect.
Coil board texture I’ve only seen from pictures always reminded me of a ‘liner’ material that is often used in baby products, like matras or strollers.
So you want to use this under glass or exposed?? Either way; It’s gonna be squishy.
Hahah, im not gonna use anything, but that top ‘fabric’ in these liners always reminded me of the ‘coil’ look. I don’t think they use the plastic fibers in between the liner tho, OP could try for the sake of experimentation hehe.
here a closup from coil surfboard instagram
On this image you def. see the ‘3d’ effect from the type of material they use. Obviously also causing the golfbal texture.
Anyways, I don’t know what the hell they use and if I would want to try compsand I’d rather do something similar to what Lemat is doing with cork.
Sport mesch at fabric store.
