What this video covers

To bond the cabin top to the deck, the crew uses a two-part methacrylate structural adhesive, chosen for its high viscosity and 120-minute work time.12:46 After fabricating aluminum components and installing a compression post, the team prepares the bonding surfaces by cleaning them with acetone.10:25 Because the adhesive requires warm temperatures to cure properly during freezing weather, the crew encloses the entire boat in a 4-millimeter plastic tarp and uses a propane heater to maintain an ambient temperature of approximately 66 to 70 degrees Fahrenheit.7:06 They mix the adhesive by volume at a 10-to-1 ratio, applying it in beads along the flange before lowering the cabin top into position.11:43 To ensure structural integrity, they backfill gaps on the interior with additional adhesive and use wooden cleats to maintain compression while the material cures.12:30 The methacrylate is capable of gap-filling up to 1.5 inches while maintaining full strength.18:53 Maintaining a controlled, warm environment is essential for the successful curing of structural adhesives in cold climates.
