I build nearly only carbon skis (or carbon/flax mix now) and never had that issue - about 50% of the mold's camber is in the final ski. But I use a very slow curing resin to ensure even temperature when resin cures. Regarding your temperature thing: IMO the bottom should be heated more to get less c...

silicon is more than stretchy enough! Made my hollow tips with a silicone sheet, the silicone membrane moves around every uneventy easily.

AFAIK flax has great dampening properties, and I think dampening along the length of the ski is more important than torsional dampening, hence I use thin Uni flax and normal triax/biax carbon. I love riding the results!

IMO this only makes sense if you build a lot of different shapes, as building this mold will take a lot of time.

Hi, 1) you will never get the base perfectly flat with a belt grinder (only possible with a stone grinder), but you can achieve very good results nevertheless. 2) The more pressure you apply, the more uneven your base will get. So I am a supporter of little pressure. Of course some pressure is neede...

My 2 woods are ash and poplar - because I can get them easily. My standard core is poplar in the middle and 2 ash stringers next to the sidewalls. In my idea the stronger wood along the sidecut helps transferring the forces from the edges to the binding. Poplar helps keeping the weight down. In a ra...

That ski is great! The only thing I don't like: Its not immune to rocks, (As any other ski). Have a look yourself: http://www.spame.de/skibau/matterhorn12.JPG Caught a rock when riding Firn in the Arlberg region (Wow, this area is paradise!). You can already see my repair approach in this picture: I...

Yes, the "real" racing skis nowadays are hard as hell and have little camber. I have a 193cm long Völkl GS racer as well, thats a really nice ski though its so hard and long . once its on the edge its going nowhere else. But for my racing skills 27m radius is waaay too much, so I built a ...

Excessive camber definitely causes chatter, had that issue in some other builds which had more camber than planned.

Not at all. And I don't understand why a hollow tip would lead to this... The contact point of the camber is way behind the hollow tip, about 5cm.

It was just a guess, we had a customer in our ski service a year ago who destroyed the whole heel of his binding by lifting his inside ski for turn iniciation :)

Hi, I used the carbon full width, the flax as well. As wood I used ash. Regarding dampness: When I test the dampening in my workshop and compare it to my Völkl GS race ski with 2x titanal, the völkl is waaay damper and stops swinging earlier. On Snow however, I didn't feel a difference but prefer ...
