Students designing custom ski cores

Colorado School of Mines senior design team, G-Turn Ski Cores, is working on constructing all mountain, powder and terrain park ski cores for the Colorado-based company, Green Light Skis. Six mechanical engineering students and one electrical engineering student are testing ski cores for bending, shear and torsion until failure.

The team creates the cores by laminating wood in various configurations and cutting them using Green Light Skis’ computer controlled cutting machine. It takes three to four days for the cores to cure after the process. Once they are cured, the team cuts out the side profiles, which range from 2-12 centimeters. They measure the stiffness of the ski using a custom designed, electro-mechanical rig they built for the project.

Mechanical engineering student Ben Paley said research shows there is an appeal to having your skis custom made. “One of the coolest things we’ve found is that people are buying around 25 percent of skis from unknown or small ski manufacturing companies,” Paley said.

Green Light Skis owner Ben Bramer started the company out of his apartment in spring 2012. He said working with the senior design team has exceeded his expectations.
