What this video covers
Johan and Malin are constructing a series of square-shaped wooden frames to rotate the hull of their new boat, which they are building from scratch at Sunhill Farm.0:21 To ensure the hull remains secure during the rotation, Johan designed these frames to fit within the barn’s limited space, necessitating a narrow clearance of approximately three centimeters on each side when moving the boat through the barn wall.17:27 He used laser measurements to verify the curve of the keel pocket, ensuring the template remains within a one-to-two millimeter tolerance.3:00 The construction process involves reinforcing plywood cradle boxes with 8mm steel backing plates, which are bonded to the wood using thickened epoxy.9:27 Johan opted to build the frames inside the barn to protect the project from unpredictable Swedish weather, despite the tight tolerances required for the eventual exit.16:26 The frames are designed to be sturdy enough to prevent any structural failure during the turning operation.18:21
