waxing problem

post #1 of 9
Thread Starter 
Hi, Im new to this forum

Anyway, I just got a new waxing iron (swix's general iron) and tested it on an older pair of skis. I set the temperature to the number indicated and waxed away. However, I began to notice the skis camber straightening so stopped. Now the camber will not return to original shape (close but not quite).

I did not notice any wax smoking, and I did not let the iron sit for any extended period of time on the ski. These skis are 3-4 years old and skied on heavely though. i am scared to wax on any other skis now with the iron. Could the temps be off?

Any help is appreciated. Thanks.

say what? camber as in the skis natural flexability?... not too shure if I am getting this correct, sorry.
the iron should not be hot enough to affect that, when you iron in the wax you should be getting the iron just hot enough to melt the wax and heat up the base a little, in order to damage the ski you would need heat much higher, and/or for a much longer duration in contact with the ski.
also how are you seeing the ski change? I have never noticed this kinda thing happening so i am interested in what's going on.

To clearify,

Camber is the shape of the ski that you would see if you put is base down on the floor. The distance between the floor and the ski measures it. it is there so that a skiers weight is distributed throughout the ski.

The skis are Rossi 9s pros from 1998 with the 91-60-79? side cut,(yes with dualtech). I noticed that they have very little camber to begin with.

When ironing I could definitely feel heat on the under side of the ski, mostly toward the tip and tail, but also near the binding. Perhaps I made to many passes with the iron.

The iron has one strange thing, the numbers that correspont to temperature get bigger as the temperature gets lower (on the iron). In the intructions it is shown the other way. have you noticed this? It was set between 6 and 7 for me just as it said on the swix wax.

Some of the older Rossi dualtech skis were well known for going soft and losing their camber when they were at waxing temperatures but the effect was only temporary and the ski returned to normal when they cooled down. I was scared the first time it happenned to me because they were expensive skis, but they were fine once they cooled down. What sort of skis are these and do you know anything about their construction?

It doesn't sound like you were doing anything wrong, if the wax wasn't smoking the temperature should be ok and you don't get that effect from overheating one spot. Leave the skis upright or on their sides for a day to cool down, I am fairly sure they will return to normal.

After working as a ski tech for many years I found that it is not really that uncommon to have a ski lose its camber temporarily during waxing. I has happened on all types and brands of skis depending on the construction. It has, however, been my experience every time that they return to normal after cooling. Base material is porrous (sp?) and it was explained to me that those little holes open up during waxing and may affect the camber or a ski in the way you describe even at moderate heat.

A waxed ski losing its camber and going into reverse camber should be of no concern. This is a natural process of a structure as it reacts internally to heat being applied to one surface setting up a differential temperature gradient in the ski. The bottom portion of the ski will expand and the top being heated a lot less will not expand as much. The result is a bend against the camber of the ski. Unless you have the ski clamped down tight so that it restricts this natural movement, you will not introduce any significant stress in the ski. That is why most ski technicians loosen one vise (when using two vises) when waxing.

Think about it, if the base of the ski is hotter than the topskin, the materials near the base would expand more than the materials in the topskin, causing the ski to flex against the camber. Did your skis recover once they had a chance to completely cool down?

I have never seen the wax iron you are talking about, are you supposed to set the iron at the same number as the wax? The swix numbering system has smaller numbers for cold snow wax and larger numbers for warmer snow wax. The cold snow wax has a higher melting point, meaning the smaller the wax number the higher the temperature setting should be. - Just a theory.

This is actually mentioned at Tognar's wax tip article. It goes into some more detail.


Have you ever hot-waxed a pair of skis only to notice they've suddenly not only lost their original camber, but actually developed reverse camber? Or left your skis leaning upright against the lodge with the bindings facing the sun, only to come back after lunch to discover they had more camber than before? Have you wondered if maybe they'd been zapped with alien gamma rays, or toyed with by Uri Geller or someone else with mind-warping powers?
This strange behavior looks pretty freaky the first time you see it (especially if you've just re-mortgaged the house to buy those beautiful new skis)...but rest assured it's not uncommon, permanent or damaging to your gear.
The primary cause of this spoon-bending weirdness is Titanal...metal sheets that are commonly used in ski construction. They're often layered in skis just under topsheets or next to p-tex bases to provide greater vibration dampening and other performance benefits. When subjected to heat...either from a wax iron or sufficient sunshine...the Titanal sheets expand at a different rate than other ski materials such as wood, foam, epoxy, fiberglass, p-tex, etc. The result is a temporary change in the ski camber, which, besides appearing strange to anyone sharp enough to notice it in the first place (another absorbing thought for introspective or paranoid tuners to ponder), does no long-term harm since normal camber returns again when they cool back down.

I just waxed my Vertigo Motions, and I looked for this. They did indeed reverse their camber.

They went back to normal after they cooled down.

Scared the hell out of me for a few minutes, though! ("A thousand dollars...gone....") :
