Hva denne videoen dekker

Sven Yrvind fabricates a new boom using epoxy and fiberglass, aiming for a lightweight yet durable construction. He trims the cured epoxy edges to create attachment points for the boom's hardware.▶ 0:00 The prototype weighs three kilograms, though Yrvind considers using Gabon wood for future iterations to further optimize the strength-to-weight ratio.▶ 0:47 With assistance from Oscar, he tests the structural integrity of the component before proceeding with the installation of the rigging eyes.▶ 2:03 The design features two eyes spaced five centimeters apart to facilitate the boom's rotation and control systems.▶ 2:21 Yrvind plans to continue refining the assembly and testing the boom's performance under load. The project demonstrates that combining fiberglass reinforcement with specific wood types achieves the necessary strength for the spar while maintaining a low overall weight.
