Larry, don’t bother gluing wood strips on the seams, that is wasted effort and will only add more weight to your kayak. You need only use a thin bead of thickened epoxy and either glass the inside of the hull or use fibreglass tape, ideally 6-oz, to get fantastic strength to your seams. I did not bother to use thickened epoxy on my seams and have good strength and wonderful stiffness along the length of the hull. I wanted my build to be light so I took certain liberties that only an experienced kayaker knows about. Do not worry about the strength of your kayak: it will be strong with properly glassed/taped seams. Extra epoxy only adds weight. The epoxy doesn’t add more strength with more used: it adds only weight and increased costs. The real strength comes from the fibreglass, be it tapes or glass cloth.
I'm about to start building my WD14. Just waiting on the sheets of wood to arrive.
I found a site that has 4x8 sheets of carbon paper for $10. I plan on placing the carbon between the plans and the wood and using a few thumb tacks to keep it from shifting. I bought a "Tracing wheel" from a fabric store for $2 (Looks like a spur) instead of using a pencil. I tried it out on a small piece and works pretty well and very fast. Plus it doesn't damage the plans if I want to use it again.
Wish me luck.
