What this video covers

Johan and Malin continue construction on their custom boat by laminating the stern extension with four layers of 600-gram biaxial glass and thickened epoxy over PET foam.1:23 To stiffen the deckhouse structure and integrate window frames, they use 50-millimeter thick PET foam panels, created by bonding two 25-millimeter sheets together.6:01 Johan designs a CNC cutting file for the deckhouse walls that includes oversized bolt holes; these will be filled with epoxy and re-drilled to prevent water ingress from compromising the core.9:42 To facilitate future metal fabrication, including water tanks, diesel tanks, and mounting brackets, the team converts a storage space into a welding shop.11:55 They widen the workshop door to accommodate a new 600-kilogram CNC laser cutting and welding machine.12:45 Using a neighbor’s front loader and steel plates to bridge a ramp, they successfully move the machine into the shop.18:53 The unit features a 1200-watt fiber laser for metal and a 130-watt CO2 laser for organic materials.21:55
