core profilers, top or bottom

Post by johneboy »

Has anyone considered the the differences to the core when you route the top vrs the bottom. When you route from the top you are cutting at some angle across the grain when you make the transition from the foot bed to the tip or tail. When the ski flexes, this end grain would act like a leaf spring since the flex would be compressing the end grain. Now if you route the profile from the bottom you would have the opposite effect of pulling the end grain apart.
Now this may be a moot point when you laminate FG to the both sides. Just wondering if this has been considered before when designing a profiler.

I can't speak to the performance/engineering parts of the question. It has been done. Bruce who builds Coiler boards does a version of this by cutting camber into the base side of his cores. You can search for coiler on the forum here, on the interwebs, or at bomberonline and you should find a good article detailing his build process. I'm not sure if they still do or not, but Volkl used to do this as well in their skis in the '80s and '90s and I believe they also did this in some of the OEM cores they made for other snowboard manufacturers up to the late '90s.
