Well here it is: If you need to ask how, you probably shouldn't even try.
Don' t waste your time, skis and knees doing this on your own. Take them to the shops and get it done by a qualified professional. It is not expensive. Instead of spending the afternoon messing around with a drill, have the shop do it in ten minutes. It will give you more time to ski.
Yeah I guess it is good to try stuff... but you know you can still get reallly hurt in your backyard and a tweaked knee is good for character but bad for skiing.
