Both are pretty similar to BD verdict, my Basics (180ish) are just a hair stiffer. Logic dictates that the shorter skis, Yoshi's at 160cm should be stiffer but they have less glass.
Basics are 300gsm Unidirectional + 300gsm +-45 Biaxial (equivalent of 18oz triax) above and below the core. And in addition approx 800gsm 0,90 Biaxial (22oz ish) below the core and a clear topsheet
Yoshi's sks are the same just no aditional biax and no topsheet.
I'm in france too, in Lyon,
I've already made two ski using carbon fiber (only) and i've made the sidewall with carbon too, a steel sheet on the top of 60cm, there are strong, very strong but the finishing on the sidewall is not very well. I do them with a vaccum press,
Now I want to do it with plastic side wall, but I do not know where I can find it, I don't see if you use plastic side wall on yours...
Do you use side wall?
If yes, where do you find it?
Thanks
sadly i can`t help you out with where to find plastic for sidewalls. maybe you should consider using wood sidewalls. would be very easy to do, just make the woodcore a little wider than the skis and that`s it. i`ve never had any problems with this way of doing it, even i was a little concerned at the beginning. but it works great and is way less complicated/work intensive.
you really don't have any probleme with water infiltration in wood core?
Do you put epoxy after cuting wood to size?
On my firt ski I had problem with water infiltration ( the srew bindings go out and water goes behin carbon and stell in the ski)
that's why I want to know more...
you say "even i was a little concerned at the beginning"
What's the problem?
i was concerned about exactly the same as you are: water and durability.
in my area there is a boatbuilder, they build some pretty good looking and damn expensive wooden boats - so i asked him what to do best. he told me that they are also using epoxy-paint to seal their boats.
i just took the normal epoxy and coated the sidewalls with it. never had a problem. if there are any big scratches in the sidewalls i just apply some new epoxy to it and that`s it.
for better protection you should angle the sidewalls with 20-30°: if you hit your skis together the edges won`t hurt the sidewalls that much by doing so...
but i definately think it does matter what kind of wood you`re using. some woods soak more, and others don`t. i used ash. i think some users on this forum don`t even seal the sidewalls with epoxy and it works fine for them...
i can ensure you, when i first heard of it i had really serious doubts regarding durability. i couldn`t believe that this should work.
but i tried it out on my first pair and i had no problems with it. i`ve tried a sidewall-construction on my second pair - and it was a pain to build and some hours of extra work. now i`m back on wooden sidewalls and i`m going to build my next pairs with wooden sidewalls.
