So I hit this rock the other day...
And my base seems to have formed a nice crevasse
I would now like to try and repair this but have some questions before i start the work (I have some experience with waxing / ptexing, but not yet had to perform a proper base repair). Ski's are 2 years old (Salomon QST99) so would rather not give up on them yet.
* Is this at all possible?
* Do I just cut out some ptex using a template?
* how do you cut out this base material (stanley knife? Dremel, ...)
* I have some metal grip + spare base material lying around (+ epoxy) so I would think I have most materials to do this, do I need anything else (Beer?)
* Anything else I'm missing?
Will keep you updated on the progress of my attempts.Because they are there

I'm not seeing core material (at least on a smart phone screen), so it looks like a normal base repair.

Looks like he maybe cracked base and that chunk by edge may have base exposed to moisture underneath. Without cutting it away you would not know. But if you cut it away then you are committed to base weld? Maybe ask skifishbum
Sent from my iPhone using TGR ForumsI need to go to Utah.
Utah?
Yeah, Utah. It's wedged in between Wyoming and Nevada. You've seen pictures of it, right?
So after 15 years we finally made it to Utah.....
Thanks BCSAR and POWMOW Ski Patrol for rescues

The edge looks a little bowed out to me, could just be the photo though.

They're Salomon QST's, what did they cost you, like $279? Just keep them waxed regularly and ski them until the ski fails, which might be never. You might ski the camber out of them before that damage causes issues, but you will almost certainly be sick of those skis and looking for something new by the time it does.

Assuming no edge damage, maggot @alpinord's video covers minor core shots.
If no core shot, skip the first metalgrip layer.
Couldn't find @Tuco's awesome thread (I search better on a laptop). It should be a sticky.

The damaged edge is now the outside edge of the ski. Ptex the base and ski it until it fails, which may be never. Prepare sacrifice for ULLR and get new skis when/if these fail.

Cut the area out. Base weld it. Grind it smooth. Touch up edge. Wax. Ski.

You sure there isn't also sidewall damage? Looks kinda like the core under that cracked base could also be cracked up in to the ski. Sidewall damage would be a clue there.Go that way really REALLY fast. If something gets in your way, TURN!

Yeah, I have such fat fingers on a phone keypad ;-)

Here's one. It doesn't cover the patch technique, but the metalgrip method is well documented.

Yep.
Any sort of delam other than just base material is going to need epoxy and base material
Edit to add: and what I'm seeing looks like a crack.

Ok, thanks for all the advice. Any specific advice on how to remove the base material (knife, dremel, teeth, ...). I tried a knife on some rock skis but they were not very impressed by the knife (or it’s dull)

That looks like the factory tune on 333 skis.

So I did a dry run yesterday with some rock skis. Everything went smooth until I tried to sand the patch down with a file / scraper. When using the scraper, the patch was pulled out of the ski and came completely lose. Upon inspection it seems that the patch didn’t attach well to the ski. I used metal Grip as primer but I think the epoxy that I used was not he best (also sanded the patch before glueing). Any other tips?
