What this video covers
Fastening chine logs to a wooden skiff requires precise alignment to avoid driving screws through the top bevel of the timber.0:32 To ensure accuracy, a custom-made wooden gauge slides along the chine to mark two parallel lines for screw placement.0:50 After marking the lines, the crew spaces screws four inches apart in a staggered pattern along the length of the chine.2:15 Polysulfide bedding compound is applied to the chine log using a toothed trowel to ensure even coverage before clamping the log into position.2:31 The team uses number 12 galvanized slotted screws, pre-drilling with a tapered bit and a modified countersink to allow the screw heads to sit flush without requiring large wooden plugs.4:10 A custom-ground screwdriver bit, used with an extension, prevents the bit from slipping or damaging the surrounding wood during installation.6:18 Finally, the side planks are trimmed flush to the transom using a hand saw guided by a reference line and finished with a block plane.8:53
