Kerfing, a Review
This morning we finished fairing the starboard bow and proceeded to lay the starboard portion of the hull back on it’s blocking. To complete the curve of the hull at the bow, we cut kerfs with the saw and knocked out the cut sections with an axe before smoothing the rest with the power plane. In order to better demonstrate this process, which has been employed throughout the entire construction of the canoe, we have compiled a series of images.
Before even looking at the chainsaw, we go to our body plans. These give us a view of the hull from the bow and stern, where we measure to determine how deep we can cut straight between two points without hitting the extent of the curve of the hull at that station.
Once we cut between these two points and the continuous grain has been cut in numerous places, we can easily and accurately knock out the remaining chunks of wood. Then, with a little attention from the axe, we have enough of a finished surface to move onto the power plane.
Using our plywood molds which were also taken from the body plans, we check the shape of the curve that we are establishing until the section is satisfactory.
This afternoon we moved onto the port side of the hull, standing the wing and garboard up on edge in order to begin kerfing again. In just a short while, we had our kerfs cut and had cleared out our waste material and tomorrow morning we will be onto eagerly fairing with the power planes.
