the bases on my beater skis (2011 afterbang) have become concave and when the snow is firm I catch edges all over the place.

The problem is the bases are so scratched if I take them to a normal shop I feel like they are gonna just grind the bases almost completely off and I'll start getting lots of edge cracks and core shots, basically ending the skis life early.

What should I do? Can I correct this at home or will I have to pay a shop $50 to potentially fuck up my skis?

What I do for a base grind for my rock skis is use a belt sander and just be careful with it Haha

The only way to fix a concave/convex base is with a stonegrind. Have you ran a truebar down the base? If your edges are full of burrs and cracks that will cause the skis to be erratically hooky too.

where do you live?
i work for a ski shop and we have 6 locations around south east PA we could either fix the issue without killing the ski or tell you if they're just toast we have a special machine that could fix this

For real.

If you're bases are concave/convex, the amount of belt or stone grinding that would be needed would remove a lot of material. Either live with bases being concave or get new skis

Basically would just return the base to its factory made form it would grind everything down but no a lot to compromise the ski or we wouldn't do it

I've seen trashed skis come back with brand new bases from it

So what your talking about is called a stonegrinder. Montana and wintersteiger are the two main makers of em.

Not related to the thread at all but seeing that you work for a ski shop any chance you sell salomon Bindings. Mine broke and I need a new replacement plastic base piece

cool thanks for the info doods, I'll probably take them to a smaller shop I kinda forgot about and see what they can do, if they can't do it I'll probably just deal with it or try and file just the edges for a few hours or something

why are you worried about edge cracks on your beater skis that are 5 years old and didnt last most people a full year of skiing?

I still like to ride around the mtn even when I'm skiing park.

anyways I took them to a shop and it turns out a delam I had filled earlier was pushing one edge out further to make a one-sided concave. A belt sander didn't fix it so it looks like I'm shopping for new park skis right now.
