board so that the centerlines coincide and Section 5 is 16 inches from the leſt (stern) end of the building board. Use two small wood screws on the centerline to secure the bottom to the building board. One should be placed midway between sections 4 and 5 and the other between sections 5 and 6.
Cut two small wedges from 1/16-inch basswood to elevate the ends of the bottom. T e bow at “Y’ should be elevated four scale inches and the stern “X” should be elevated two scale inches. T e wedges can be tack-glued to the building board. (Figure 10) Check that all the frames are the correct width by holding them centered on the appropriate station line with the frame center mark on the cleat aligned with the centerline of the bottom. T e sharp angle on the outside bottom edge of the frame, the chine, should fall on the edge of the curved perimeter of the bottom board.
T e point of this chine will now be removed. Using a 3/16-inch circular template, circumscribe the point of the chine, marking the arc with a pencil. (Figure 11) Use a round fi le to remove wood within the arc. When the frames are lined up along the chine these holes on the inside of the bateau become the limber ways to allow water to drain.
Screw uprights about 3/4-inch wide, 1/4-inch thick, and 9 inches long to both sides of the building board at both bow and stern. Placed them about an inch beyond what will be the extreme ends of the completed bateau. T is will allow working room for installing the sheer planks. Glue shims on the inside faces of these uprights where the stem and stern pieces pass between them to hold the leading edge of these timbers in line with the centerline of the building board. Once glued into position on the bottom, these timbers will be held at the proper height with bits of
