I noticed in the manual photos that the deck beam seems to be laminated in a different orientation than what I found in my kit. The plywood layers in the photos are oriented forward/aft whereas mine are oriented up/down. I went back and looked at the kit part list to insure that I wasn't about to use a similar 2 pieces of okoume that were intended for another purpose and I don't see the deck beams pictured. I also do not see the wooden tabs used to secure the carlins to the deck beam, either in my pile of parts or on the parts list. Am I using the right pieces for the deck beam and am I to assume that I will be fabricating the wooden tabs myself out of leftover okoume?
