thanks everyone… i really appreciate everything about this forum, with bob's tutorials as an incentive i've embarked on learning the wonderful world of (s)ketchup!
pictured here is a skateboard deck vacuum laminated from several layers of .02 mm bamboo veneer, fiberglass, and carbon fiber. it has a complex pediform which provides an asymmetrical foot position (front toes raised/heal lowered - rear toes lowered/heal raised) for both goofy (right foot in front) and regular (left foot in front) stances on a singular platform… the manta skateboard deck has an s-cambre shape with a scooped nose going into a w-concave flowing into a convex then bending up at the corners to form a tri-tail. the consistent flex pattern is derived from the shape which is 3d in the sense that neither the top nor the bottom surfaces form parallel planes. since it is a hollow structure i used nature's senetic architecture to form the internal arched supports within the flattened bamboo culm design.
the outcome is a very light platform that could handle the excessive stress of slalom racing and even performed nicely when ridden on vertical transitions. as you can imagine, from the outside it just looks like a bent piece of wood… only when dissected can the beauty in it's internal structure be revealed.
