Is this normal, or do I have really thin bases?

post #1 of 8
Thread Starter 

So I've noticed that one one pair of my skis, I can see the outline of the edges through the bases. I bought these used from ebay a few years back, the skis are Volkl Racetiger GS, race stock 23m version.  Here's a picture of what I'm seeing, though it's harder to see in the pic. Also, I can see them much more clearly if I've just hot waxed and there is a layer of wax still on the ski. 

So should i be worried about this? I'm guessing it won't be a problem, but I'm wondering if it is ok to take them for a stone grind, or if they would be down to nothing afterwards?

I'd say they've been stone ground enough. The structure looks good. Why would you even consider grinding them?

Their days are numbered, but certainly still quite skiable.  No more grinds though.  Also be careful when waxing them.  Make double sure the iron isn't too hot.  Other than that they have plenty of days left on them.

Well I wasn't actually going to get them ground, I really like the way they ski already, but I was basically just wondering if it was possible to do it in the future for whatever reason.

Someone, either you or the previous owner, was too fond of stone grinds. So, stay off rocks.

Will do!

 I've never actually gotten these ground, I bought these back in 2010, and I think they are the 2008 version, so whoever sold these on ebay as "very lightly used" was probably pushing it, or some stone grind operator got a little trigger happy

Wow, how thin does black ptex need to be to see through?

I don't think you're actually seeing through the bases; I think you're seeing base burn.  If you look at the part of the edges you can see "through" the bases, the actual metal is under the dark black, shiny parts.  My guess is that your wax iron has a concave base, and is hitting the metal edges of the skis, causing the parts of the base touching them to heat more and absorb wax better.  You're moving the iron too fast for the other areas to heat as much and absorb as much wax, so they're getting worn faster.

 

You can minimize this by sanding the base of your iron to make it as flat as possible, or pulling up on it while you wax so the iron doesn't touch the edges directly.  A flat iron is by far the easiest solution, if I'm right about the cause.  I wouldn't stress another grind, when it's time.
