Marine plywood is not needed and is usually soft Okume, .5 in/13mm AC Ply is the cheapest high quility ply you need, Polyurathane, oil base paint, not epoxy is a better sealer for a BIG flexy board. any size 150+cm is good, the size 160X50cms is universal.
FINS ARE NOT NEEDED, AND HINDER RIDING IN 6IN OF WATER. If you need fin like feel, use a concaved sides, skatey feel striaght.
You get 2 doors out of a piece of ply, plus some wood for what your wife projects.
I'd try for the 12mm if you can find it. Try other materials if you can't get marine ply.rlander wrote:Hi all!
1) I found out that most of my local shops donÃ‚Â´t sell 12mm marine plywood (probably because I live inland). Some do sell 15mm. Is it ok or will the board be too thick/heavy?
I can't help you with that one other than to suggest you grab a pic off the net and scale it up. Kiteboard outlines aren't to critical though - make a shape you're happy with and see how it goes!rlander wrote:
2) IÃ‚Â´m building my board based on the Door. Can anyone post the measures?
You can start with a square edge on the bottom surface (for clean water release) with either a small radius curve or a square edge on the top. Rail shape is developing, but there isn't anything too wrong with simple shapes IMHO.rlander wrote:
3) How should the rails look like? Will rail design affect riding?
"Glassing" is the process of putting layers of fiberglass and resin together over the outside of the board. It can be used to increase strength, add waterproofness, improve surface finish AND add weight. In an experimental board you could start without and then add fiberglass later if you decide the board is too flexible.rlander wrote:
4) After i cut, sand and rock the board, I will apply epoxi. How many coats should I use? Why do a lot of people talk about "glassing"?
Most epoxy isn't UV stable so I'd suggest epoxying it first and then painting it.rlander wrote: 5) I will also stencil the board. Should I paint over the wood and then epoxi it, or should I give it one coat of epoxi, paint and then another coat?
This is a hard one. I've made some vacuum bagged carbon & foam fins and there is no way it was worth the effort. What I'll do next time is simply make a mould and then cast them out of resin & glass. Hopefully I can cast in the bolts and unscrew then when it sets. Fins is one of the harder problems to solve IMHO.rlander wrote: 6) I also found the fin prices to be wayy too high. Anyone have plans for fins?
