Early Season DH/SG Ski Prep from Copper, CO
The preparation of downhill and super-g skis can be long and tedious but can ultimately mean the difference between making the podium or falling outside the top ten. Although every technician has mysterious tricks of their own to make speed skis extra greasy, there are several generally accepted preparation concepts.
When a ski is fresh out of the wrapper it often requires "shaping", which can be achieved by beveling the edges of the top sheet layer with a file or fine grit sandpaper to ensure smooth tracking through the snow when the ski is tipped at an extreme angle. Some folks may dismiss this step as unnecessary but if every inch of your skis is fast and smooth it can only help.
The next order of business is usually removing the excess sidewall material (both the plastic and secondary metal edge) with an adjustable sidewall planer. Another crucial aspect is smoothing the entire face of the sidewall with either sandpaper or a scotch-brite pad. Again this will help the ski cut through the snow with the least amount of friction (i.e. more speed!).
From here the edge setting process can begin. Nowadays most high end speed skiers are running a 3 degree side angle and a 1 degree base bevel. This has proved to be the most optimal amount of aggressive edge while still allowing for fluid gliding.
Once several cycles of hot scraping and deep brushing have occurred it is time to begin hydrating the speed bases. This can be achieved through normal wax/scrape/brush cycles from 10-20 times or through hot boxing cycles progressing from soft to hard waxes.
The take-home message here is that where DH and SG skis are concerned, everything matters. Those little burrs that can be ignored on SL skis can act like engine brakes at DH speeds of 80 mph. Smooth is fast and fast should be the ultimate goal!
