Cosa tratta questo video
Johan laminates a watertight bulkhead for the chain locker using PET foam core and leftover fiberglass scraps from the hull construction.0:34 The layup consists of two 600-gram biaxial layers and one 300-gram woven layer on each side, providing extra stiffness to contain potential water ingress.1:00 He tabs the bulkhead into the hull with a 125-millimeter runout using two layers of 600-gram biaxial glass, following structural specifications from Dave Gurr’s *Boat Strength*.7:50 To minimize dust and preserve router bits, he uses a jigsaw to trim excess fiberglass close to the core before finishing edges with a router.16:32 He positions the second bulkhead using a laser to ensure accurate alignment before bonding.20:55 The process avoids vacuum bagging, relying on manual wetting and weighted curing to achieve a flat, compacted panel.15:29
