  • Patent number: 4046091
    Abstract: A tubular pylon secured to a deck is provided with a core telescopically and slidably received in its distal end. In securing the deck to the hull, a well is provided in a shoe to be received in and secured to the hull. Glue is inserted in the well and applied along the intended glue seam between the deck and hull. The deck/pylon assembly and hull are then assembled to be clamped in a jig. During assembly, the core acts as a plunger to force glue in the well of the shoe upwardly about the outer surface of the pylon to secure the pylon to the shoe. The core is frictionally held by the pylon to exert a desired force in holding the shoe against the inside of the hull while the adhesive sets to secure the shoe to the hull and the deck to the hull.
