Has anyone else had to do this many passes?
The worst I have encountered was a pair of "premium" ski. 12 passes with a coarse wheel to reset the factory angle to 3°. This is with the side wall cut back so interference from the side wall plastic. Just pure metal edge removal. The odd thing is the extra passes were only required for the front of the skis. All four edges from the binding toe forward. The back end of the skis took 6 passes to reset.
Had the same experience with another pair of skis with the same issue. Same "premium" brand. Front of the skis took 8 passes while the back needed only 6.
However, the more disconcerting issue that surfaced was the inconsistency of the factory side edge angle. three quarter of the way through the edge angle reset, the ski edges looked like a serrated kitchen knife with irregular scallops varying from one to three inches. That happened with five (05) pairs of same premium brand skis in the last two years.
