ski geometry and weight

Post by endre »

I've been thinking of posting this for a while, now I had some spare time so I printsc'd my excel spreadsheets of ski geometry.
All numbers are measurements of one ski.

I'll explain the norwegian if there is something you don't understand:

Modell= name of ski
år=year
så lgd=length
kr lgd=length without tips (running length)
bt lgd=back tip length
ft lgd=front tiplength
f ski=front ski length
b ski=back ski length
%=percent mounting point
tot%=percent with tips
bak=reference width back ski
midt=width mid ski
fram=reference width front ski
tupp=widest tip width
R=meters turning radius
bt ar=back tip area
kr ar=runing length area
ft ar=front tip area
tot ar=total area
bt=back tip height
ft=front tip height
sp=camber
bak=thickness thinnest at back
midt=thickness thickest middle
fram=thickness thinnest front
gr=weight (of one ski)
gr/cm²=weight/total base area

it says in your profile you are an industrial designer. So this sort if information goes hand in hand with that.

The link in your profle is a custom ski program, dont spose you design skis for a living then?

The information in that database is emmense. Did you 'aquire' all of this by research or did you physicaly weigh each ski and measure it etc?

im just curous

cheers

I have measured all the skis, a hell of a job! -and then I just give it away like that! I must be crazy;)

The "custom program" is just a teaser- stay tuned

thanks for these tables endre.

a lot of interesting things to read out of them! so i recognized that my skis are not that heavy as i always thought, they are pretty ok and beat a lot of the listed skis in terms of weight! thanks a lot for sharing these informations.
