I finally made it!!!!!!! :D :D :D :D :D

I pressed my first ski. But I couldnt check how they are, because I startet to press them on sunday morning and I had to leave in the evening. But I hope that I will return in about two weeks! I'm really looking forward to that date!

But I had 2 problems:

1. The edges didn't fit perfectly. And the edges popped of the base as you explained it in the tutorial. I glued them several times, but everytime I made a test, they popped off again. I managed the problem by simply putting a nail at the ends of the ski (see pic). The nail hold the edge on place. My opinion is that it is better to bend the edges perfectly to the mold. But maybe it depends on the used press.

2. The time was running away. I used Epoxy L + L, that means 40 minutes time. After 41 minutes I closed the press.... :)

Guys, thank you for your help! Without you and skibuilders.com, I would never had build a ski!

I made some pictures of the layup. check out

I hope after 2 weeks in the press, that everything is fine with the ski.

Two weeks???
The epoxy L+L needs at least 12 hours under pressure plus 8 hours.
In 24 hours they are done.

Go skiing!!!

On Sunday I have tested my new ski. I only finished one ski, so I combined it with a 1080. (171cm)
It really worked well!!!


I want to thank you for your tutorials, advice, pictures and materials! Especially to davide. without your edges and base I would have never build the ski.

Super!!!
That means that bith vacuum pumps and pnematic presses are not necessary to build skis. The wood/clamp press can be a real, cheap alternative.

yeah, it was really cheap! 8)

i payed 25 euros for it, but i already had some materials, for example the plastic plate. but you could also use a wood plate.

So, at the end, you made the skis with a single ash board, rather than using vertical lamination, is it right? Did you pre-bent the board with hot water? How thick was the core?

yes, i used a single ash board.
2mm thick at the tips, 11mm in the middle.
i didn't bend it before, i just put it in the press and it was alright.
