Screwed

Postby bay surfer » Sat Apr 20, 2013 7:42 pm

Made a two new Jig tables, Mirror opposites, so I can make layups upside down and bottom up.
Two new screwed epoxy/glass wood sandwich blanks, one board with 4oz glass, sandwiched between 1/4 in AC ply and 1/8 in birch ply, and one with glass tape, Dry wall tape stingers in a X pattern and length of the board. Both Blanks have good flex, not stiff. The stringer Blank has more twisty flex and 3oz lighter.
A little filling (screw holes) and some Poly and paint, and I'll try to Break them in :thumb: [img]

Great job. What is the final specs for length, width, rocker, and weight?

How do they ride?

Making some new boards to try to destroy this year, one board just a simple single sandwich, but will have 1/4 in edges, the other board, a double sandwich with two layers of glass epoxy.
Note in one of the pix I have the boards from last year. The larger one broke after 3 sessions due to a Knot in the middle of the ply right under my heel. The Yellow board still going strong after one season and its the best riding board I've rode.
Finished pix of this years boards to follow.

About 13mm Concave, concave flattens out at the edges, but actually the 3 part rocker would be considered Moderate, both boards have nice flex pattern should be a comfortable ride, like last years boards, but lighter.

Nice effort:)

Huge concave = less maneuverability tho.

Duno if you've tried many boards but you can always build one flat on tips and a concave in the middle, like 3-5mm. It might be a huge difference, but that depends on your riding as well:)

Good luck.
