Designed a weird fishtail, wanted to get anyones advice
Ik I could’ve gone to ski builder forums for this but as far as geometry and everything goes I wanted to get anyones advice as to how it would perform if I built it. Core would be poplar and beech with carbon stringers.
used uhmw in tips shaped the core with hand planer, tons of carbon in tail. the whole thing was more of a big experiment than anything else. i realized a lot of flaws early on,so next design is gonna fix all that stuff

nice, yea you definitley learn as you go.
for finishing i usually use a jig saw with an aluminum cutting blade. dont put too much pressure against the edge, it will cause the blade to bend. better go slow and a bit further away from the edge so it cuts at 90. then use an angle grinder with a flap disk sander to give the side walls a bit of an angle.
dont skimp on the base grind. i usually get them to do it with the belt sander and then stone grind for structure. it costs about $100. really thats gonna make the biggest difference in how skis ride. even after they "finished" check the base with a straight edge to make sure the edges are pretty flat with the base. most tuning shops havent ground skis out of a press before. ive had to get them to do it 3 times over.
if they cant get the bases flat, it probably because the mold just wasnt strong enough, or there were no relief cut in the bottom of the core for the edges.
when you mount them up, i would use some epoxy in the drill holes just to keep the bindings from tearing out. most companies add an extra layer of fiberglass or hard wood underfoot to prevent that.
if the edges pop out in the tip and tail when you ride, its likely because you didnt soften the metal before attaching it to the base (annealing?). there is no saving that when they go.
did you use any vds rubber in the tail? carbon is not very impact resistant in my opinion.
Yah I used vds everywhere, so hoping that will save me. I work at a shop so as long as I run our tech beers he’ll do whatever I need him to. But this is definitely going to be a very expensive learning experience
