Theoretically, it is not hard, assuming that you are handy with tools and careful. Get a measuring tape, drill and a posidrive screwdriver and have at it. On the other hand, it is probably one of those jobs that should be left to trained techs at your local ski shop. Unless you can borrow a mounting jig specific to the binding, you are in for a world of potential mistakes. And these being ski bindings that are supposed to release and save your ass from breakage, mistakes are not a good idea.
Back before I bought my first pair of good skis, I watched a local friend mount bindings on skis for one of his kids. He'd been doing it for years since he has three kids. Not particularly difficult. But I wouldn't consider doing it myself except on skis that I didn't care about if something didn't come out right. Don't have the patience to measure 3 times, drill once. :-)
I have those concerns as well. I’m only considering it because I grabbed an old pair of long skis at a garage sale. I’m not sure if I’m willing to buy new bindings for it, will probably move some from an old pair of skis and I’m thinking that might be too sketchy for the shops in the area. I’m gonna read through the tgr thread now. Thanks for pointing it out MC
I mount all my own system and race bindings which have pre drilled holes. Particularly with a racer who has 6 or 7 pairs of skis it’s a good skill to have. I’ve also worked in shops demo days etc and have the knowledge plus the tech manual so I feel comfortable doing it
The one thing I would not even consider doing is drilling without a jig for that particular binding. Strongly advise against it as it would way easy to screw it up particularly if you don’t have a ton of experience working with bindings
