Is it ok for skis to (temporarily) lose their de-camber when waxed?

post #1 of 14

Just waxed my sandwich SL skis with Holmenkollen blue. I never payed any attention to it but both skis lost their de-camber almost totally and are now flat. The wax is still on so I dont know until tomorrow morning if the skis are permanently without de-camber or not. The skis were naturally heated so that made a difference but its more likely that its the surface tention in the wax and that its only temporary. Lets hope so. Any advice highly appreciated.

What really matters is how much tension they have when your skiing them in a curve. You have to ski them to find that out.

I know, and I have been skiing them for a couple of times now but it takes some time to get used to new skis. Now when I look at the skis one of them has much less de-camber than the other. Could it still be the wax that needs to get scraped off or could it be that the ski is somehow damaged? The original plates were removed and replaced with Marker Piston Plates.

If the ski has a metal layer right next to the base, it can decamber when warmed by the iron, so nothing out of the ordinary there. Should go right back to normal when the ski cools off unless something else is wrong.

It's a problem if your skis DON'T decamber when hot!!

What you are saying is that the natural decamber in the ski should not flatten out when hot. If they do then its a problem. I found out that my skis did not go back to same decamber after cooling off. What is the problem?

All skis should decamber when the bases are hot. All skis should also go back to normal when cool. If yours didn't go back, then perhaps you over-heated the ski and caused a delamination hidden inside the core?

Like the others have said, TDK6--when you heat the base, it expands, more than the cooler top sheet, causing the ski to decamber--to lose its built-in camber--and possibly even bending the other way, into reverse camber.

It should return to normal when the base cools.

Best regards,

Thanks guys for your input. One ski did not reach its default camber after cooling off. I know this for a fact since I measured the camber when the skis were brand new and posted the results here at epic. It measured 18mm. 9mm each. Now one is 9mm and the other is 6mm. I dont think I overheated the ski but what if it got bent while I was bashing gates? What if its a bad quality ski and lost its camber after quite moderate use? My older ski pairs all have lost their camber in straight proportion to their use.

I redid the bases at a pro shop to 0,5/87. On the ski with less camber I had some really annoying tail slip. Swapped skis and the same kept happening to the same ski. Sharpened the edges racer sharp and moved my bindings back 5mm but the problem continued to pop up. Any thaught anybody? Is the ski ruined?

Doesn't sound good, tdk6.

Unless you think you might have really over-cooked it when waxing, it's likely that you bent it somehow--gates, bumps, something.

Is it still under warranty? If there's no visible damage to the ski, and it's under warranty, they might replace it.

Good luck!

Best regards,
Bob

Time for a new ski.

The camber is like pre-stressing(steel cable under tension) in concrete support beams; it means that the beam is able to transfer the force with the designed displacement. Your ski is obviously just deflecting instead of deflecting with significant force applied to the edge. Sorry to be the bearer of bad news.

Did you have them held tight by a vise when you waxed them?

No I did not over cook the skis nor did I clamp them into strong tention while heating them up with the iron. I think one ski is bad thats all. I talked to the importer and he said we have to send them to the factory. Well, you know how well that strategy works mid season . Anyway, those skis are soooooo incredibly nice I hate to give them up. The ski with less de-camber is acting a bit weard like the edges at the tail were not sharp even though they are. Its a very powerfull ski. Did not ski the 2008 model but this is way better for racing than the 2007 model which still is one of the best SL carvers I have skied on. They are much softer. First SL race is next week, then we will see how well the new model works in gates. It has been great at practise.
