Jesper--

There are probably 2 important factors when building with square edged strips.

1) the bevel does change over the length of the strip--greater bevel where the curve of the hull is tight and next to no bevel on the flat portions of the hull.

2) A tight fit on the outside is important. You're right about the v-shaped crevices becoming potential air bubbles. Close attention to temperature will help in reducing the air bubble effect, but deep crevices will soak up epoxy, starving the cloth when you wet it out. It is easier to go for a tight joint outside by over beveling a little bit and allowing the gap, if any, to be on the inside, where it will be less noticeable.

Also, recognize that there will be some planing and sanding to fair the finished hull shape. It's an inevitable result of stripping around a curved shape with flat strips. The outside corners of the strips will be high and will need to be planed off.

By the way--it looks like you have some wonderful grain in the wood you are using.
