What this video covers
Andy corrects a structural error on a custom hatch cover for a Bertram Moppie project by removing and replacing an off-center stringer.▶ 3:32 After identifying that the original center stringer sat one inch off-center, he cuts a new, properly aligned support to ensure the hatch openings remain clear.▶ 4:28 He bonds the new stringer using Fix-O-Flex, a pre-thickened, flexible filler chosen to withstand vibration and shock.▶ 12:55 The fairing process involves multiple thin applications of fairing compound, using progressively wider trowels to achieve a consistent profile.▶ 9:49 Between applications, he sands the surface with 60-grit sandpaper to scuff the area and identify low spots, which appear as darker patches against the sanded, lighter surface.▶ 14:57 He also applies fairing compound to the port and starboard pockets to address minor gaps.▶ 16:02 Proper alignment and thin, layered applications of fairing compound minimize the need for excessive sanding.
