I tuned mine for the first time
Monday. I guess I don't see what you guys are fussing about. I filed mine flat with a medium large file, then just ran my smallest file along the sides,
flush and square by hand
But, they only had about 8 hours of actual skiing on them
so this was really just a touch up
I did see an itty bitty lip of rubber/plastic where the sidewall meets the edge. I just held the file against that parallel with the edge using little lateral side to side strokes along each side tip to tail. Then I went over it with a stone. When it is time for a major tune, my plan is to just run a large file across that and carefully take it down flush with the edge when the sides really need some attention. Then I'll tune them just like the other twenty skis I've tunes myself with advice and guidance from others, reps, ski techs, etc,, over the past thirty years. Mine PEs are probably different than yours though because they are the 05/06 model
with the 80 mm waist.
Regardless, taking down a bit of sidewall is sometimes what has to happen if you want an edge beveled beyond 90 degrees or what is flush with the sidewall when it came out of the plastic. Frankly, I think an edge bevel on anything other than a true race stock ski is a waste of time. Unless you're trying to shave hundredths off a 30 second run down bulletproof ice it isn't worth the effort.
