Man fits OSB bulkhead into curved sailboat hull
What this video covers
Andy replaces structural bulkheads by first creating templates from OSB before cutting the final panels from Coosa board.▶ 3:05 To ensure a precise fit without creating hard spots against the hull, he cuts the templates with a slight gap, aiming for a fit that slides into position without requiring force.▶ 3:53 He uses a laser level to ensure the new bulkheads are plumb and square, which simplifies the future installation of a door frame.▶ 16:01 When transferring the template shapes to the expensive Coosa panels, he aligns the straight edges with the factory edge of the material to maintain structural integrity and minimize waste.▶ 13:34 He notes that while the bulkheads should touch the hull for support, they must not be wedged in, as forced contact creates localized stress points.▶ 4:12 The process involves iterative trimming and fitting until the panels achieve a tolerance within 1/16th of an inch.▶ 16:29
