摘要

Few operations offer as much of a guarantee for getting your boat's shape right (and symmetrical) as creating a properly set up construction jig made with accurately built and properly positioned station molds. A good construction jig will prevent the formation of unsightly sags or bulges, which detract from the desired curvature of the hull. A construction jig can be enhanced and adjusted to reflect the complexity of the hull. A simple skiff might require just a few molds, as its shape is relatively simple and the planking is usually thick enough to fair itself between supports. On the other hand, a boat built with thin and floppy plywood planking, or with narrow strip planks, might need twice as many station molds to keep things fair. A sophisticated hull shape like the Haven 2Vi might require a mold for every single steam-bent frame. In this article, we'll take a close look at molds: how to ascertain their shape by using information from the lofting board and how to build them. In part two, (in our next issue), we'll get into the finer points of setting up molds on the buildingjig.
