What this video covers

The owner of the 38-ft sailboat Antidote fabricates new deck prism housings using epoxy and vacuum bagging after initial attempts with polyester resin failed to bond properly.0:55 To secure the trim rings to the new fiberglass deck, the owner tests the pull-out strength of M5 machine screws threaded directly into G10 laminate blocks.7:25 Using a shop press and a 500-kilogram load cell, the tests confirm that 1/4-inch thick G10 holds over 2,000 pounds of force without thread failure, significantly outperforming traditional wood screws in plywood.14:21 The owner uses a router template and a solid carbide fiberglass-cutting burr to cut the final openings in the housings.24:26 The process includes using a foot-operated switch for the drill press to ensure straight tapping of the G10 mounting holes.22:09 The project concludes with the successful removal of the cured part from the mold, aided by a PVA release agent.21:08 Testing confirms that tapping G10 laminate provides a secure, inert mounting point for deck hardware that resists water intrusion.15:55
