THE SPINE OF THE SKI
To make the constructions infinitely repairable we had to improve the construction of modern skis. The main problem with a standard constructions are "hidden surfaces" of materials that need treatment before regluing. These are typically plastic sidewalls, plastic tip spacers and aluminium alloys. We can also not use foam cores since it will degrade to an unsustainable pulp over time.
The most important part of our ski is the core. Our skis are actually pressed in two directions, first we press the sidecut of the skis in to the core, so the wood of the sidewall follows the shape of the skis, avoiding most of the end grain in the surface of the sidewall. This way we can open up our construction and use resin infused hard ash as sidewall material.
The wood is pressed to shape, cut and symmetrically bookmatched. When the core is CNC machined to the final shape of the ski It gets channels inside to distribute moisture and relieve tensions. This makes a light construction that will not rot and is very unlikely to warp, keeping it flat and stable. The core goes all the way over the edge of the ski, avoiding any vertical laminations over the edge which is a typical problem area in normal sandwich constructions.
The wood in our cores also goes nearly all the way out to the tip of the skis, where it is closed by steel and rubber. This makes a light but super strong and "shovel proof" edge that works like teeth: Hard materials enclosed in soft, not the oposite which is the industry standard. These tips can be repaired if damaged, unlike tips with plastic infill.
M6 inserts are machined in to the cores at the rocker transition areas as utility anchors.
