A sailor replaces a failed headsail furler while anchored in the Bahamas after the unit seized due to 20 years of salt and corrosion.7:19 To remove the seized lower extrusion from the furler, the sailor uses a heat gun, a grinder with a cut-off wheel, and a hammer to break the bond.7:48 After cleaning the components with sandpaper, the sailor shrinks the metal by placing the part in a freezer for one hour, allowing for a successful reassembly.8:59 The installation requires loosening all standing rigging to create enough slack to slide the new unit onto the forestay.3:08 Once the furler is installed, the sailor re-tunes the rig under sail in 15 knots of wind, keeping the cotter pins out until the mast is properly tensioned and straight.18:51 The sailor also uses a 3D printer and ASA CF filament to fabricate a custom locking device for the furler assembly.4:57
