Downunder: The stickers are not stickers..can be....took a photo of the owner and embed it in my logo...and then laminate it
The rails is one of my main focus...I really believe they change so much the behaviour of the kiteboard ..so there are made quite carefully...with different profile..in different points....the material is epoxy..pigment..filler...
Prebenting the core..is agood idea...but as I have set the rocker(adjustable steei rocker table) already including the springback..I woukd rather not readjust it....now! Thank you.
Ok, I still don't get it, how did you embed this graphics? Printed on a rice paper? Tell us more
The problem with epoxy rails is UV. I have a PU samples stored and can show you how rails look on my board after 3 years compared to samples. Very light change. Also, epoxy is much more brittle than PU, so it can't survive if the board is dropped on the concrete from ie 40 cm. Depending where it drops of course. I'm talking tips.
Is your rocker table adjustable? I see a lot of effort in making a table but my idea was to spent minimum and gain maximum
So, simple perspex sheet, 5-6mm thick is my rocker table. Nothing more. Stored behind the door.
When making a core, the wood strips are not glued all together. The core is glued all together when glassing the top. That makes less springback possible in my experience since only wood strips are forced to bend, not the complete core (how is it said, "together we are stronger" - so loose strips are not that strong!). The more strips you have, the less springback you get. It is that simple. Less strips is easier to work with.
Full carbon on top is, well, a waste. FG is way better coz you can leave the board on the Sun (as I did this morning). Carbon on the contrary, you can bake an egg on, the temperature is exceeding epoxy TG (an assumption for a picky readers
, and might delam. The FG will never delam coz the Sun is going through a FG, like through the glass. Than it hits a wood, which is an isolator. UV might affect epoxy tho, but, not the TG. Temperature is TG related, hence we don't see the Airbus planes black, that would be an disaster.
