Outcome seems reasonable, so I think I add couple layers and the base and fibreglass...
|Three layers glued|
So, I added only two more layers of birch veneer with fibreglass, one set at the top, one at the bottom. And an extruded base at the bottom to finish the whole thing. I'm using SP106 epoxy that I bought from Kevra. Amount of epoxy needed is roughly 4sheets/250ml+50ml, and that is without fiberglass. For one layer of fiberglass between two veneer sheets, the amount I use is roughly 250ml+50ml, or 200ml+40ml depending on the fiberglass. One fiberglass that I have used is from Biltema, just biaxial, and I have no idea about the quality of that. Another one that I have used is triaxial fiberglass from MBM.
But here is the final product, looks nice, feels quite stiff, and rather light. It should be clear from the picture what I meant with the convex/concave shape. Now just some finishing work and grip tape to the top. Oh, and there is one good tip for the griptape that I'll show next...
The grip-tip is simple, and rather cheap: Take a closed-cell-foam, (for example here http://www.vaahtomuovi.net/node/17) and add a normal skateboardgrip on top of that. No icelayer forming, good grip on every weather.
If you're wondering how to glue the eva-(closed-cell-)foam on top
of the board, maybe you can try one of the spray on glues. I suppose many brands have spray-on-glues. I just tried 4connect glue that is designed for the car tuning guys (I have no idea what they glue, some speaker/foam/whatever maybe). Seems to make excellent bond even to the laminate that I'm now using as a toplayer.
