How thick is the owners/operators manual?
The results look great!!! Just wondering about how much base/edge is removed and how many times can you do that to a ski? With our members that get so many days a season it seem it could shorten the life of the ski.
Thanks. I'm really excited about the range of base structures at our finger tips. When there is more skiing I'll be doing some base structure comparisons.
When a ski is new or in very good condition, a single pass with the edger on the side and base is enough to set and rejuvenate the edge. A pass or two over the stone for the structure. Not much material is removed. You could do that 10 or 20 times and not have the base or the edges get too thin.. I haven't worn out a ski of my own with frequent tunes although I have a lot of skis in rotation so take that for what its worth.
For skis that are in fair to poor shape, usually most of the work is needed to flatten the base so a fair amount of base material comes off, but only that in excess of the height of the edges. If it is edge high, then of course edges come off. Either way it is just enough to make the ski flat and the edges true.
I feel it is better to have your skis tuned (at least evaluated) more frequently than most people do. Skis will be nice longer with care and (IMO) last longer as well. A true bar and edge bevel guage used regularly will help you get the most of out your skis by being able to see when things are getting worn and addressing the problem when it requires minimal work than waiting until they ski like crap. Also remember, if your bases aren't flat, edge to edge, then stoning your edges to keep them sharp is going to change your bevels, theoretically making them higher bevels. If you are stoning your base edges with your base high, you are increasing your base edge bevels. That is one reason that base edge work is recommended in conjunction with a base grind: to insure a flat base for a reference point.
