What this video covers
The owner of a custom boat project installs and laminates a stainless steel shaft tunnel to house the propeller shaft. After determining the optimal shaft angle between 9.5 and 10.9 degrees to ensure proper alignment with the engine and propeller clearance, the team fabricates a structural support for the tunnel.6:26 This support, which functions similarly to a skeg, is reinforced by welding stainless steel plates to create an I-beam profile, minimizing potential vibration.18:09 The installation process involves securing the tunnel with stainless steel bolts, followed by extensive fiberglass lamination using roving, 800-gram woven fabric, and 450-gram mat.30:45 To build volume and structural integrity, the team uses a mixture of resin and chopped fiberglass powder for fillets and filling gaps before applying multiple layers of structural lamination to the hull.29:51 The project concludes with the tunnel fully anchored and prepared for final heavy-duty structural lamination to ensure long-term durability.34:28
