    ski geometry and weight

    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.

    -to get the "whole" picture you can check out the flex curves of the same skis:
    http://www.endrehals.no/Flexcurves%202007.pdf


    I'll explain the norwegian:

    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

    Wow, thanks! That will take some time to digest.

    The running length and mount point info is really nice to have.

    Awesome spreadsheet.

    Any way to have a copy of it for sorting purposes?
    g/cm2 and running length are important fields that come to mind.

    Hey Endre,

    Good Job! One question:

    Is the PDF file the same you published some time ago or is this a new update?

    Thanks

    Pechelman, would you attach the tables above to the ski weight sticky? Thanks, dude.

    not quite sure how to read the flex graphs. the steeper the bell curve the stiffer? how does it work? i always thought my pipe cleaners were kinda stiff for a twin, but not as stiff as karmas
    EDIT: never mind, learn to read alex <-

    Thanks for the 2008 PDF, endre! And your new SFI numbers are a great way to compare skis.

    Are you going to post this year's excel spreadsheets? Very useful for weight, running length, and all the geometry details.
