Pic 19:    This is not a funnel, as a humorous friend quipped. It is in fact two old tin cans filled with lead, weights made by my late father in his woodworking adventures. As they served him, so they now serve me; simple and effective. The whole set-up is all to make sure the keel stays in place while the glue dries - note the little slip of wood underneath just to make sure that all the weight is going where it's needed.
