Great video Petter. Looks like you need the handicap!

Glad to hear you had a blast on those wild skis.

I had a thought for this thread this week after checking out my friends kick sled (Sparkfabrik of Sweden). Build one with powder runners! I will do it with a pair of throw outs someday and post more.

Although the thread started with the Megawatt core and what the purpose of 3D top is. I am not talking the Megawatt per-se. Just any ski with a 3D core and the benefits that may provide. That is what got me interested in the thread-What does a 3D core do? I build with a vacuum bag and a beveled core...

I got a reply from BD: The CNC shaping of our ski cores allows us to create three ribs towards the tip and tail on skis wider than 100mm underfoot that beef up the torsional stiffness of our boards (i.e. Formula One technology), while skis that are 90mm underfoot and less receive one main CNC channe...

[ It doesn't work that way. A better analogy would be: take that same original bar, and cut two grooves in it. Does it somehow gain torsional stiffness? No it doesn't. It also doesn't gain longitudinal stiffness, but that's because it is one solid material. Things get more complicate once you start ...

I think the milled top surface ADDS torsional stiffness. The old Atomic Beta's are the first ski I can recall with a shaped top sheet and they promoted the enhanced torsional stiffness. Black Diamond has be doing it since the CrossBow. In my mind the concept is such: compare a flat bar and a channel...

check out ScottyBob online- design tab. forum won't let me post the link being new and all

I used the Elan method recently on some tele skis and was pleased. I can tell that the skis do not bang off of each other as much- smoother transitions. A bitch to tune though.
