grinding skis so they come out flat - is it possible?

post #1 of 3
Thread Starter 

Every time I have had skis ground they have come out slightly concave.  I had to finish them with a file to get them flat. 

 

Is is possible to grind them flat?  Am I too fussy?  Are some machines better than others in this respect?  I would appreciate comments from people who have used these machines on this issue.

Most skis can be ground perfectly flat on a properly dressed stone. Some skis are too warped already, especially in the tip and tail, to flatten without excessive grinding. If you put a trubar on the ski before grinding and the gap is more than a mm you' ll never get it flat without grinding through the base. Even less on a true race ski where base material can be as thin as .5mm. Also, some pow skis are rockered to the edges in the tip and tail by design, and you dont want to flatten.

   A little concavity (1/2 a mm, middle third of the base, edge to edge) near the tip and tail of the ski is acceptable for recreational, sl, and gs skis...as long as the outer 1/3's in these same areas are flat. You DON'T want concavity ALL the way across the width in these areas, though.
