k2 rivets

post #1 of 6
Thread Starter 
Just noticed that some of the tip rivets on my K2 Public enemy's were ground flush by the base grinder. Should this be a cause for concern. If so are they replaceable Thanks.

That probably means that your bases are ground pretty thin too. Those rivets are quite a bit thicker than a base so if they ground those down that much I'd be a little worried about how much material they took off the base. How many times have the bases been ground?

It takes a lot of grinding to grind down a rivet.

This was the first base grind. They actually took off very little. I compared them to a new pair of PEs that I have. Since the rivets stick up quite a bit from the base, its possible to grind them without removing too much material from the base itself. It appears that they just were not very careful entering the ski into the grinder. Not all of the rivets were ground.

Not really. UHMW PE is very resistant to abrasion, which is why base grinders need integral horsepower motors and feed pressures in the ~50-100 pound range. They'll eat a rivet in no time.

The cause for concern has little to do with the rivets on the ski, and everything to do with why the shop guy wasn't paying attention. Grinding rivets isn't exactly a good thing for the dress of the stone. (understatement) That said, this is an easy mistake to make. Don't step quite hard enough on the feed bar, and this is exactly what happens. Mistakes like this are encouraged by folks (customers and employees) who think base grinds should extend tip to tail.

No it doesn't! I have "removed" mine in one tuning session. They are cosmetic only. They can fall out of the ski entirely without any structural problems actually!
