Ive done this many times, even to a pair of badass X-screams (i know, im dumb)Ive done it to about 5 pairs of skis with moderate success:
1. I used a blowtorch, so you have to be careful with it b/c it applies a shitload of heat. Start by clamping down the ski on a table outside or something. Obviously, have the tip your blowtorching hangoing off the end. You want to heat the ski on both sides, alot of times the top sheet will bubble little, its something youll have to live with. Try to heat the metal edges the most, as thats the main part that keeps the ski from bending up oin its own.
2. While applying adequite heat to bopth sides and the edges, ake a pair(or two, if a freind is helping) of channel locks or loicking pliers and apply pressure slowly bending the tail up. Keep blowtorching the ski while doing this. Be careful, dont let the ski split b/c you didnt heat it up enough before you started bending it.
3. Once you think youve bent the tail up as far as you need it(your judgement), quickly take the ski off teh table and dip the tail in some near snow, or a bucket of cold water, something that will flash freeze the matel so it doesnt bend back to the original shape.
4. Let ski cool for about 1/2 hour in the snow.
5. This is optional, but will help your ski from delaminating in the future, I drill 2 tiny holes in each tail of the ski accros from each other. Then find some sort of bolts that have a rounded head, so that itll be flush with the bottom of the ski. Put the bolt in the ski with the nut on the top of the ski.
6. Repeat for the other ski
this has worked for me on both, wood and foam based skis, although it holds up much better on wood skis. I recomen doing this only to skis you wont mind letting get destroyed, this usually only holds up for about 1/2 a season before some sort of delamination occurs, but my X-screams went thru a whiole season pretty well, so Good luck! ITs not as hard as it may seem, and dont let people tell ya what to do with YOUR skis, i may not like 1080s, but damn their expensive, i wouldnt want to ruin them early that way.
