What is a structure (rilling) tool? These are manual tools that set patterns in the ski base. The pattern and depth of the tool can optimize (or hinder) the base structure on race day. Tools often roll but some are fixed and others still may have a gear to “cut” the structure into the ski…

How do you guys determine the best hand structure solution on race day? The Intermountain Nordic Division has eliminated the waxing variable with a wax and application method mandate. This leaves ski selection, hand structure, and kick waxing options open to test. I’ll ignore kick wax testing and we can look at ski selection and…

Despite what the calendar says we are not in winter mode around SW Montana! Crosscut Mountain Sports Center has about 3-4km of “open” trails and in-town/south of town (Sourdough) is dead. The machine has been turning out batches of skis to the local nordic community as word gets out! Thanks for supporting this endeavor. We…

We had real winter here for about 2 weeks. It was amazing! As of Monday, December 8th it has disappeared. We had some intense wind and a bit of warmth and like a hair drier the snow, in town, has disappeared. Crosscut Mountain Sports Center is holding on but time will tell as we navigate…

Post treatment of freshly ground nordic skis depends on the structure applied. Course vs Fine and if a hardening process was complete. Generally, if the ski was hardened, re-wax (blue) → ski → and re-wax after each ski. If not hardened. FINE GRIND: Brush the ski with a soft steel or bronze brush. Apply a…

The process of grinding nordic skis is complicated and time consuming which is not an excuse or justification… All skis that arrive are analyzed with a steel scraper for severity of damage. e.g., flatness (convex or concave or both), surface damage, edge damage, etc. and then work begins. Step 1. Skis are placed into a work…

Yes, generally, most nordic skis can be ground. What nordic skis can be stone ground, specifically? Modern ski bases that have a sintered polyethylene base are the best candidates for grinding. Current generation performance/race skis that are well cared for can easily handle 3-5 grinds. Classic, skate, skin skis, and zero skis can all be…

Nordic stone grind development…by Jim? No, I did not develop the grinds, but Lars Svensson did. Who is Lars? He is the “Goldmaker” or grinding guru and has spent his career developing and refining his CD and LJ structures, and training operators on his Tazzari machine. You lost me… He has made more fast skis…

…Universal cold grind that runs well in new snow conditions across a broad range of temperatures (SLSu and SLCu). This is the description of my current universal cold grind meant for use across cold locales that enjoy cold snow and may need moisture management or run well in a “broad range of temperatures.” This grind…

Have you seen a convex ski base or have you felt them? They are rounded from edge to edge like the underside of a dish or bowl. Tips and tails are often concave (more like an upside down shovel) but the meaty portion of a ski is more often than not convex. Convex ski bases…
