Surffoils, I'd bet several of us would willing to help discuss writing up docs if you want to publish a little e-book or something. But I understand if you are thinking of commercializing something.
I think there are a lot of ways to get paid, including selling plans, a book, or even kits. I'd like to build my own and I think paying for the info is fair or even selling 3D CNC files so they can be cut out of plywood or whatever. I did this in my own business and now companies pay me to consult on their products.
I'm betting there are some brands who would pay you (and U.K.) to help them make a product out of this. Admin is right, but you also don't have to just give everything away. I think a crowd sourced book could get you started and establish your ideas as your own.
I'd be willing to help write it just to move the art/craft along and I'll bet there's enough talent here on the zone to get you started.
Same to you Charlie, if you need help packaging or documenting stuff, let me know. You guys did a lot of hard work and I'd love to contributor you two getting rewarded a bit.
You have basically written a book over the years, it's really just collecting it and putting it into a format.
