Mike,

I'm using clear recycled red fir. Had a 21' 2x10 lying around with some rot/damage. Had to rip it on the radial arm saw because my shop isn't long enough where the table saw sits but I could go in one door and out another with the radial saw. Got 5-21' strips, 1-17', 2-13', and 1-12'. I cut the strips 1/2"x1" and they're quite flexible. I don't know if I need to be concerned about flexibility as the boat's intended use is for small local lakes. As a novice (I''ve never been in a kayak) I don't even know what flexibility does for you. One other question: There are some pitch pockets--mostly dry. I plan to fill with putty and seal with shellac before finishing the frame. Do you think I'm on the right track there? Thanks, Tom
