De-Tunning Skis

post #1 of 11
Thread Starter 
Hi All,

I have a pair of freestyle skis that I have been skiing all mountain on, they have an edge angle of 88/1.

I now wish to just use these skis only in the park, I wish to completely 'de-tune' these skis so not to catch on rails and landings.

This is alien to me as all my life I have been sharpening skis, so what is the best way to round off and create a 'good' edge for freestyle skis (I realise that this will destroy them for all mountain skiing, but as I said all I want them for is the park)

Thanks for your help

There are all kinds of ways to de-tune edges, including and not limited to:
-ski parking lots
-ride the rails
-a pebble along the edge
-billy goat skiing
-ski New England
-use your imagination

For a controlled and de-burred approach, run an Arkansas, grinding stone, etc or gummy at 45° along the edge until you are happy with the dullness. Keep it in your pocket and do a little at a time until you are in spinning and grinning, grinding bliss.

in 2004, curtis bacca and i were prepping skis for the atomic skiercross team at the x games in aspen. a box of skis arrived for steel spence, one of atomic's park athletes. as curtis and i where putting our love and sweat into those skiercross skis, steel comes in opens the box takes out these fresh from the factory park skis, and proceeds to run the underfoot edge back and forth on the cement curb outside of our ski room!!!

i offered him the opportunity to wait until the bindings were mounted and then skitch behind my suburban into downtown aspen, however he told me that that would not work as well as the "curb tune".

Thanks, I think i'll stick the stone or gummy at 45°. Not sure if I am quite skilled enough to do a 'curb tune'

I would just run a few rails, but then again I don't know, honestly, anything about trauma-park skiing.

Dull them before you do any rails or boxes.  Catching an edge on a grind is not fun at all.

The point of detuning them is so that you don't catch an edge on rails or boxes in the first place. Great advice.

If you have them tipped the right way, the edges won't catch and will be dull soon enough.

rails are typically harder metal than ski edges so yeah if you balance and tip the right way then unless there is a bur on the rail which you can do nothing about you won't catch on a rail.  On jumps you should be with a weird edge tune depending on length, stiffness, and radius of the ski, but again if you land flat you'll be fine.

Experienced park skiers will be able to get away with straight rail grinds on tuned skis, since they have the skills & balance control to avoid catching edges.   For curves & s-rails, they'll still want properly prepped skis, which in this case is dulled edges.

Someone who is just learning rail grinds will have a pretty high probability of catching a sharp edge and getting injured.  Self-taught skiers unfortunately find this out the hard way on a regular basis.

Skiers who have some guidance from a good coach (e.g. someone with CFSA training) will be shown how to dull their edges first for safety and ease of learning.  A 1.5 degree base bevel is  often suggested as well.
