What this video covers
The crew of the wooden boat *Arabella* continues hull planking and spar fabrication while preparing for the arrival of additional shipwrights.6:51 Work on the mizzenmast involves applying a taper using a router and a custom-built jig to correct a previous gouge.0:59 The team reduces the mast diameter from seven inches to six inches to decrease total weight and windage, while also achieving a straighter, more uniform profile.22:32 To ensure structural integrity, the crew installs bilge stringers, which provide rigidity and help the hull resist twisting by crossing plank lines.5:17 These stringers are particularly important for the boat’s bent-frame construction, which relies on mild flexibility to dissipate impact loads.6:23 During the milling of oak planks, a short circuit in the Delta planer causes an electrical shock, prompting a repair of the machine's wiring.17:24 The team emphasizes the importance of unplugging all shop equipment at night to prevent fire hazards.18:01
