Assemble the hull members from the bottom of the ship and attach the necessary parts in order to assemble the hull sequentially in the short direction. It is characterized by that.

  When dividing the hull members forming the canoe hull in the longitudinal direction and allocating the divided pieces and other parts to the wood board, for example, a plywood of an existing standard less than 1 meter in length can be used, Production costs can be reduced.

  Since the laser cutting is performed on the wood board with the laser beam, the divided pieces and other parts can be accurately cut. At this time, since the laser cutting is performed while leaving the connecting portion, the divided pieces and other parts do not fall off the wood board, and therefore handling and transportation can be facilitated. On the other hand, the width of the connecting portion can be easily separated, for example, about 1 mm.

  The cut pieces and other parts laser-cut by the laser light are cut off from the wood board, and anyone can easily and accurately assemble a canoe hull from the cut pieces and other parts.

  The canoe manufacturing method according to claim 2 of the present invention is such that gourd-type joints are connected at equal pitches in a plan view along the longitudinal joining surface of each divided piece, and the gourds of the opposing joining surfaces are connected. It is characterized by alternately engaging the joints of the mold and joining the divided pieces in the longitudinal direction.

  Since the gourd-shaped joint can have a large joint surface due to its round shape, the joining surface in the longitudinal direction of the split pieces can be firmly joined.

  According to a third aspect of the present invention, there is provided a canoe manufacturing method in which a dovetail groove is provided along the short-sided joining surface of each divided piece, and the dovetail groove and the dovetailing surface of each of the divided pieces are engaged with each other. Each divided piece is spliced in the short direction.

  When the hull members are joined together in the short direction using the combination of the dovetail and the dovetail, even if the side plate member that joins the bottom member that is one of the hull members is erected with respect to the bottom member, both members There is no deviation from the longitudinal direction and the short direction. Therefore, the hull can be reliably assembled.

  According to a fourth aspect of the present invention, there is provided a canoe manufacturing method, wherein each part is provided with a convex tenon, and an adhesive is applied to the convex tenon and inserted into a tenon provided in the hull member, and then inserted into the tenon. A wedge is applied to the mortise from the outside of the hull to assemble and fix each part to the hull member, and after drying the adhesive, a portion of the tenon protruding from the outside of the hull is cut.

  Since the mortise was inserted into the mortise and the wedge was hit from the outside of the hull, anyone can easily assemble the hull, and the hull shape can be accurately formed.

  As described above, according to the canoe manufacturing method of the present invention, there is an effect that anyone can easily manufacture a canoe at a low cost.
