New ski edges...seems to be thinner edge/less edge on one side of each ski

post #1 of 15

Is this normal for a new ski? I've got some brand new Mantras I had tuned at my local shop here, and seems to be not very much edge material on either edge vs my Fischer GS cheaters, and I also noticed on each ski the right edge has less metal than the left edge. I'm kinda worried about not getting much life out of these if regularly tuned, and wondering if the Montana machine has anything to do with less edge material on one side vs the other or if this is normal for new ski construction?

I don't have all the info you need, but to start zeroing in, a few points. Different ski models use different edges. Narrower edges, though possessing less steel to file over time, are considered higher performance/faster than wider edges; this because the steel does not react to terrain the same way that the sandwich body of the ski does, and the steel has greater friction than a sintered base. Next point, the Mantra most certainly was built and factory tuned to produce edges of the same width on all four edges of a pair of skis. That said, nothing would be easier than to unevenly machine grind the edges on a pair of skis. All it would take would be for a friend to tap you on the shoulder and ask you if you skied today while you are working on a pair of new skis.

So is this an issue or should they ski normally? It's not a huge difference but definitely a little less edge on the right side vs left side on each ski. Don't really want to have them ground again to even them out and lose even more edge life. FYI its a radial done on a Montana machine.

Bring them back to the shop, a fresh pair of boards need to be treated like jewelry.  It appears your tuner was ill trained or just bad.


Compare the edges to a new pair on the rack, if they are indeed wider, ask the shop manager WTF?  If they are a well regarded shop they will make things right and you will leave happy.


If you are still unhappy, you will need a new shop, and can then be free to trash talk their treatment of your new diminished skis when anyone asks.


Note, if you ask for a 1 and 3, and the shop asks "what"?  Run away and find a shop that knows what they are doing.th_dunno-1[1].gif

   rogerMN, what you describe is not normal. Go to your shop and inquire as to why...I suspect possible tuning error--but I may be wrong. Could be manufacturer defect, I suppose. Either way th_dunno-1[1].gif...

Yea, I agree, a tuning error that they fixed (?)


The skis will ski fine. you may want to think about doing your own tunes from now on.


I've been DIY for about 13 years, haven't had a bad tune since.


Also my AC40's with about 150 day's on them have lots of edge left and great camber still.

I bought all the basic tuning equipment but haven't started serious tuning yet other than waxing and getting the rust out on the side edges. Having said that my new race skis are starting to wear out and just bought a pair of used, so one of these days ill buckle down to it.

I agree DIY is a way to go if you have passion and time for it. You may have to invest a big chunk of money but will end up saving in the long run.

Let me clarify...the edges are equal as far as side edge material, it's the vertical side that differs. Upon examination, I noticed the ridge on the sidewalls above the edges are different right side vs left on both skis. Wondering if they were just manufactured this way and is normal?

   Yeah...hard to tell. Take a few more in different lighting and from different angles rogerNM. We can help you, but we need a bit more info via images...

You'll run out of base material and width of the edges long before you run out of height of the edges. Unless you get base grinds or file way too often you'll wear out the stiffness or just get tired of them before you run out of anything. Getting a tune to sharpen the edges is a bad idea. If you keep at the side edges with stones,  just use a file on the side edges where you have a ding, and leave the base edges alone your skis will last a lot longer. The average shop is going to run them through the machine which will take off a lot more edge material.  Get a true bar or any accurate straightedge.  If the bases are flat and have visible structure they don't need a base grind, and you can sharpen and wax yourself in a lot less time than taking them to a shop, and with a payback on the tools of 4-5 tunes.   

They look the same to me--or close enough it doesn't matter.

Not many skis come perfectly flat from the factory, nor do they have accurate edge bevels. If you hit a rock on one edge, that edge will need more tuning to get back to smooth. Same goes for the base. One ski may not be as flat as the other, therefore you need to grind that ski more to get it flat. You are left with unequal edge and base thickness. It's a fact of skiing, hitting things, and tuning. The ski will not be tuned with exactly the same amount of material off each ski/edge. If you are tuning each ski/edge to perfection, you will end up with different thickness. Just something to consider once you start hitting things and having them tuned.
