Atom removes seven unused through-hulls from a Cape DORY 30C during a refit to reduce maintenance and flooding risks.▶ 0:00 He eliminates two toilet intake holes, the engine cooling seacock, two cockpit drains, and two transducers.▶ 0:04 To remove the seacocks, he cuts slots in the mushroom heads with an angle grinder and removes the bodies with a pipe wrench.▶ 1:08 He grinds a scarf into the hull around each hole using a 24-grit disc on a 12,000 RPM angle grinder, thinning the fiberglass edge to allow for a structural patch.▶ 1:45 He applies 1208 biaxial fiberglass cloth with US Composites 635 epoxy resin and a three-to-one medium hardener.▶ 4:26 He fills the holes with colloidal silica-thickened epoxy, then layers progressively smaller fiberglass circles—eight, seven, six, and five inches—to match the scarf taper.▶ 5:13 After curing, he sands the patches flush and applies a fairing compound similar to West System 407.▶ 11:16 A final coat of epoxy resin seals the repair before priming and anti-fouling.▶ 13:39
