Hendryx here Lennart!

I lost your email adress, thats why I have not mailed you!

Anyway, what is the flexibilizer you are using?

I´ll give you a call otherwise!

Hi Davide!

I am always routing out seats for edges in my cores. You do not seem to do that! Do you not get a concave base?

Hello waxers! I read about this a year ago and started to think about my old Blizzard Firebird Comp wich I scraped with a sharpened steel scraper! Since then I have not had a pair skis with such glide. I waxed them once a year, did not matter I think, and I always had the best glide in all condition...

Hi Tony! Yes they do, they relax 5-10 mm depending on length. I have a soft light core that does not contribute to the flex very much so you may experience differeces from my relaxation. But otherwise it sounds good with 15 mm of camber in your mold! Though I have a little less camber for a 170 cm s...

Hello! I cure my skis at room temp and have 10-15 mm camber built in to my moulds, the amount of camber varies with length. Sometimes I speed up the curing process by heating to ~35-40 celsius and I gain more camber, about 5 mm. I think it is the steel edges that expand and contract different from g...

Just a little tip!

Remember that the, do not know the word for this, modulus for two layers increase with the sqare of the distance between them. So if you increase thicknes from 10 to 11 mm the flex increases with 20 %. Small changes makes big differences!

Hi Davide!

I think some of the values are for laminates and some for single fibers!

Here is a link to values for single fiber values!

In swedish only but I think you can figure things out!

All the best!

Thats what I thougt to Davide but WC skiis have very low camber. If you have a look at the core profile on WC skis you can see that they have a more stabel center and very flexy tips and this is probably because they want high edge pressure under foot for grip and tips are more for steering the skii...

No I can not bend them together but what I mean is that the skis will bend this much and not break! What I did is that I placed one ski in a deep ditch with an angle of ~60 degrees in the bottom and, this was hard to my heart, jumped on it. The ski was standing like an U but they did not even give ...

No! It should be the other way as carbonfiber has a negative elongation coefficient. It means that carbon expand when temperature decreases and vice verse. Carbon in the bottom gives a lower camber at lower temeperatures. For a +-45 degree carbon the increased break elongation would be the root squa...

Hose-man you got a point there but we put rubber between the steel edge and the glassfiber to equalize tensions beetween these two materials. They have different heat elongation constants which means that they contract differently when getting cold! What I mean with rubber/steel mix is that if you t...

Biggie! In my opinion you should make a lowcamber ski that is a little stiffer to compensate for the pop. And now to materials for pop. Be carefull using carbon fiber to increase pop. Carbon fibers have a negative elongation coefficient which means its lengths increases when getting cooled while gla...

Hello everybody! I see you have problems with my low camber theory. Well, it is not just a theory it comes from testing. The benefits of low camber on hardpack is that the skis are very smooth from edge to edge and are very easy to adjust between turns. If you have alook at real World Cup skis you w...
