What this video covers

Edgar and his crew reinforce the propeller shaft tunnel on their boat by laminating multiple layers of fiberglass to achieve structural integrity.13:54 After initial attempts resulted in air bubbles and wasted material, the team adopted a three-stage lamination process, applying one layer per day to ensure proper curing.6:28 They filled deep voids with solid fiberglass scraps and a mixture of resin and fiber powder before applying structural layers, which include biaxial fabric and 800-gram woven roving.2:55 The finished tunnel wall measures approximately 5 to 6 millimeters thick, consisting of at least eight layers of 800-gram fabric plus additional manta and 330-gram cloth.21:26 To manage the difficulty of laminating heavy fabric overhead, the crew uses a resin and fiber powder paste between layers to secure the material.16:27 The completed structure now accommodates the mechanical seal with the required clearance.22:14 The team plans to finish the surface with epoxy fairing compound before installing the shaft support bearing and homokinetic joint.23:45
