Progress and Clamping
October 24, 2017 § Leave a comment
This is the fun part of the build — laying strips and watching the canoe slowly take shape. This particular build features a loon inlay.
For the first ten or so rows, I used straight strips (in other words, no bead and cove), partly because the sides of the boat are upright and the strips sit nicely against each other, mostly because I don’t want to router a bunch of strips if I don’t have to. When I get close to the curve, I router one row that is cove only. This, then, helps me transition to the bead and cove until I get around the curve.
When clamping, bar clamps work best before the hull starts to curve. When you get to that point, the pressure of the clamp can force the strip away from the form. So when I get to the curve, I employ a variety of tools.
Bungee cords work great. I place the cord either inside or outside the hull depending on where I need a bit of extra force. Note that I use the bead part of a scrap strip to protect the cove. The blue clamp is there to press the strip against the form. In the second photo, I’ve used a C clamp and a clamp with a scrap piece of cedar to keep the bar clamps from pressing the strip away from the form, as the force at this point is as much out as down. The clamp with the wooden bracket (on the left) works to keep the strips against the form, but the downward force is seldom enough by itself to do the job well. In the third photo, I’ve used a longer bungee to wrap around the newly glued strip (again using scrap bead pieces to protect the cove). When I can’t use bar clamps any more, I use bungees almost exclusively.
And that’s about it for now.
