It's time to fasten the first binder strake onto our TotalBoat Sport Dory. We glued the scarf together on the boat and that's very important so that the angle between the two boards is exactly right. If that was off even one degree the plank wouldn't fit when we bend it into position. With the glue dried we can take the plank over to the bench and touch up the scarf with an electric plane and then a block plane. Then we'll bring the plank back over to the boat for one last dry fit to get our clamping procedure worked out. Once that's done it's time to apply some poly-sulfide. We're going to apply a few beads to the transom and the stem where the plank will contact it and also to the broadstrake where the binder strake will overlap it. Once we get the piece clamped into position it's time to fasten it down. We're going to work our way from the middle fastening toward each end of the plank. Before we drill we want to apply an additional clamp to the frames so that they are pulled up tight against the inside of the plank. Then we can drill and sink our screws through the overlapping planks and into our plastic frames. We're going to put one more screw into each frame 3 inches up from the batten that way when remove that batten the frames will still be held in their proper position.
