Made my first ski of the 2015-2016 season. Well I did make one at the end of the 2105 season... But this one is a bit more innovated in the core design and materials. The goal is to make it fairly light weight, damp, torsional firm, nice even longitudinal flex AND earth friendly (tough combo). Primarily this ski is made to rip up groomers and then some.

Sidewall: Ipe
Epoxy: Entropy CLR
TopSheet; Man-made Oak from Certainly Woods
Base - 4001 Black
Bi-axial 45degree Flax 350 gsm
Cork.8mm and 2.5mm thickness
Uni-CF 4.4oz
metal edges
VDS
Tip/Tail Spacers: 2.5mm poplar
Flax is a bit tricky to work with. It's difficult to cut, very fibrous. My rotary cutting knife didn't work on it so you need a well made sharp pair of scissors. Second thing about flax is it's deceiving in the amount of resin you need. It doesn't wet out like FG. I used a total of 47ounces!! Way over did it. Got a lot of squeeze out, which was good but wasted a lot of resin. Each ski weighs 3.5lbs. So I think I missed the light weight goal

but I can live with that. I'm not usually that concerned over weight.
I used .8mm sheet cork to fill in between the edges and act as a damping layer. I rabbeted a 2in x 12in recess in the front of the wood core and laid in a 2.5mm sheet of cork, another damping technique, we'll see if it makes any difference.
I laid a 2in strip of uni-CF down the middle of the each side of the wood core and then flax over the CF.
I used Entropys slow hardener. Problem is it take 8 hours to set up at room temp. Even at that point it was still far from cured. Full cure time at room temp is 7 days. I pressed the skis over night. When I took them out the epoxy was a bit soft still so I put them back in the press for another 8 hours just to be safe. They came out fine the second time. Then they sat on the work bench for 7 days.
Tonight I cut the flashing off. The resin was cured as far as I could tell, It was hard. Tomorrow I'll bevel the sidewall, LPU the topsheet and sidewalls, grind the base, etc.
The skis seem to have a nice flex and torsionally solid. I think this could be a winner. I'll report on how they ski once we get some snow.
An upside to the flax is there's no itch factor like FG, it handles good and is supposed to be a more damp material than FG. I use the uni-CF since the flax only comes in biax and uni-CF give me the longitudinal strength .
Just need to nail down the amount of resin to use.
If this skis like I think it should. I'll convert from FG to Flax/CF
