The chine is clamped in position while it is sprung around the frames to determine the correct angles for the frame notches. It is imperative that the chine mate firmly in the notches and does not merely bear on one corner of the frame.
The builder is shown using a scrap of plywood as a jig to determine the set-back of the chine from the forward edge of the stem. The stem will eventually be "faired" or beveled so the line formed by the chine will extend to the centerline of the stem. If the design utilizes a chine blocking member, as this one does, it may be necessary to adjust the chine blocking to compensate for the thickness of lumber you are using. Without chine blocking, the position (up or down) of the chine on the stem is determined by allowing the chine to take a smooth (fair) bend around the framework. Although the exact height can vary, the opposite chine should be at the same height. NEXT
