Feral 2011/12

Post by threeninethree »

So Ive been slacking the last year. Ive been ridiculously busy with everything but ski building. I did manage to make these last week.

Size: 180cm (135-107-126) 6mm camber
Core: Maple w/(2)poplar strips 2.25-12-2 (tip 60mm rise in 400mm), (tail 45mm rise in 250mm)
Sidewalls/Tipspacers: UHMW
Base: Isospeed 7200
Fiber: 22oz triax/3" strip 5oz uni CF above and below core
VDS on top of edges and full area of tip and tail
Topsheet: PBT sub'd by Coda/ graphic done in photoshop and illustrator
Epoxy: Super Sap 100/1000
Press: 60psi@180f for 60min pulled out hot.


Image
Fresh out, you can see the graphic alignment drawn on the protective paper so no element got cut off. Some of the paper stuck to the top cassette,topsheet unhurt.

Image
Glueing the sidewall in my DIY glue press (I also use this to glue the core block and join the core slices.)

Image
Cores glued, and inserts drilled. These were profiled on a crib in a planer.

finished skis (the marks are just glare)

3/4 edge wrap and no sign of tip fall, although the curve up is gradual which helped as I did not prebend.

Tip and tail rise came out nice. The sidewalls are beveled to 18d.

Very nice! The white sidewalls really pop with the dark top sheet. I love your clamp jig too, that's pretty clever.

Thanks Twizz, Im pumped with how they came out.

I just grew tired of clamps and trying to keep the wood flat and square during glueing.

Awesome looking skis! I love the way you beveled the edge of the topsheet and it shows a nice white border around your graphic when looking straight on. Those are probably going to be some pretty burly skis. Your core profile doesn't stay at 12mm to long underfoot does it? You mentioned you pulled them hot. Do you have a cooling rack/board for them to post cure in? Or do you just lay them flat for a few days?

Thanks Pow,
I took a flapsander (120grit) on a hand drill along the edge of the topsheet and finished it with a exacto scalpel.

They are burly close to 400mm underfoot of flat, as far as cooling I just lay them on the workbench with some rolled up cloth to support the camber for 2 days and cut them out.

threeninethree: very nice design. I really like the topsheet design. Was the CF uniaxial? How much stiffness did it add, you think? Excellent work!

Thanks !

Big Kam : Ya the cf is uni, and im not sure how much it added to them since I
have no pair with the same coreprofile and no cf. But I was trying to get the same or close to the stiffness of an old pair of Solly Xscream series I have. I always liked how solid they felt, and its pretty much there. The only missing piece was the sollys had titanal, which greatly contributed to the feel. I think I might cut one of them cross section, and the other length wise to see what made them tick.
