Swix and others put out some good lit on tuning. The books should be available at any quality alpine or backcountry shop that carry tuning supplies. Some folks may tell you to check out the teletips tuning video, but after watching it, I definitely disagree with some of the concepts, especially the order in which they are presented (why sharpen edges after waxing).
We'll be holding a ski tuning clinic led by our head tech Zac on Saturday at the Colorado Freeheel Fest. Also, tuning supplies will be 15% off for the weekend. The discount on gear and beer will pay your gas from the Springs! Check Upcoming Events at www.themountainshop.com
for the schedule.
A good set of equipment to get you started would contain:
Vices (2 or 3 point; 3 point is better for cap skis and generally easier to use)
Side Edger or 8-10 inch mill bastard file, file guide, and clamp
Scotch brite brillo pads
Base edge bevel sleeves and 10-12 inch mill bastard file
Sticks of p-tex (black or clear) and lighter
Waxing Iron (w/ no holes)
Horse Hair/Brass Combi Brush
After this basic list, you'll start to collect other supplies, including:
The initial investment can be about $215. You're basically paying for 7-8 shop tunes. It pays off in the end and can be a fun way to drink beer.
Hope this helps!
