You need about three time less carbon to get the same stiffness.
Carbon under compression is just a bit stiffer than glass, while in tension is much stiffer, so it is better to put a layer under the core than above the core.
I dos not really matter what the big companies are doing.

They introduced this thing few years ago. It is very easy to make it at home. For example, if your ski is 80mm wide at waist and 120 mm wide at tip, just use a unidirectional glass tape 80mm wide: the fiber density (glass/ski width) will be higher in the middle than at tip and tail. Then use standa...

These are mine plywood skis, built using 4mm thick, 3-ply birch plywood.

I made 4 or 5 pairs like that, before switching to vertical laminated woodcore, which I bought already tapered.

Plywood skis are good, no particular problem using them.

Well, I would built a second one and use them for skiing. Anyway, it was a good idea to extend the reverse camber/sidecut to skwals.

You can buy the R&G type L with hardener L (40 min.). It is easy to use and great for skis.

In this topic http://www.skibuilders.com/phpBB2/viewtopic.php?t=1601 I posted a video about some very old wood skis, used today in central Asia. I think that, besides the construction method, also the geometry is rather interesting. http://s291.photobucket.com/albums/ll304/davide72/NEOski.jpg The sk...

A friend of mine used a screw press and he did not use water.

That is nice to see that somebody is experimenting a bit, rather than just copying a pneumatic press.

Go ahead.

Have alook here:

They show how to make neolitic skis, from trees to snow.

Tu n'as pas bien lu le livre du TCF: il faut du vapeur pour plier les skis, la moule était place’ dans un boite connecte a une marmite. Tu peux essayer des plonger le pointes dans l'eau bouillent pendant quelques minutes. C'etait du sapin? Il faudrait essayer avec du frene. http://www.skibuilders.co...

I measured the deflection of the ski when loaded with a 31.8kg weight at its midpoint. 1)Would it work to just measure the percentage of camber lost when the ski is set on a flat surface? It seems that my skis with more pop are less prone to losing camber when set down on a flat surface. All these ...

My skis have plenty of it.

It is not very smart: in case of big cambers, there will be no long wood fibers running entirely from tip to tail.
