What this video covers

Andy modifies the transom of a Bertram powerboat during a conversion from twin inboards to twin outboards with an Armstrong bracket.2:12 To prevent water from flowing from the deck into the new storage area, he fabricates and bonds composite extensions to the port and starboard sides of the existing transom structure.4:28 He uses a pre-thickened epoxy cartridge to bond the extensions, noting that the material provides superior strength and convenience for small-scale bonding.9:57 After the initial cure, he evaluates the joints and decides against applying fibreglass cloth over the seams due to the tight, complex geometry of the area.17:36 Instead, he opts to build up the low spots and fair the transitions using a structural epoxy mixture thickened with silica.19:09 He plans to shape and finish these areas to create a sealed, flush surface for the future storage lid. The project demonstrates that most composite modifications can be salvaged or corrected through a process of grinding, filling, fairing, and finishing.5:12
