Abstract

A traditional wood core downhill ski can only be mounted three times before the cores become compromised by holes in them. Binding plates can be used but require the user to ski high above the ski and can decrease performance by making them harder to maneuver. One way this could be solved is by a removable integrated binding plate in the ski so that it provides lateral support with the core of the ski, but doesn’t require the user to ski above the top of the ski. The basic system derives from the idea of the binding plate. Screws can be interchangeable in tapped metal but not in wood because the screw will tear the wood and deform the threads more than in metal. A traditional ski has a wood core in which the binding screws are installed with wood glue. Removal of these screws compromises the wood core and makes those holes unusable. Testing will be done spring quarter should show if the ski designed can behave like a traditional ski, hold the same pullout strength on the binding screws, yet be mounted more than three times. In this project, the ski will be totally redesigned, and will require meticulous calculations for user safety.
