Bubble in Base - Am I Screwed??

post #1 of 24
Thread Starter 
Hi all. I have always tuned my own skis. I do not claim to be a pro, but feel that I am fairly competent at it. Last night, I was tuning my skis...I am fairly certain that I did not have the iron too hot. Everything was status quo. But as I was passing my iron over one of my skis, the base bubbled up in a small spot. I would say the bubble had about a 1.5" diameter and was bubbled "up" about 2-3 mm. I carefully and patiently flattened it back out and after the wax cooled and I scraped the ski, it seemed fine.

Any opinions on what I should expect? Am I screwed? Is the base going to come up there again on its own, or is it possible that it "re-adhered" to the ski...? They have a few good seasons of abuse on them, so spare me the euphemisms...lay the truth on me...I feel I need to know.

Many thanks.

By screwed, do you mean it's an indicator of a bigger issue or that this 'isolated' bubble means your skis are done? When you flattened the base was it cutting away base material leaving a void with thinner material or it re-adhered (or not) by pressure and heat?

If an isolated area it could be cut out and replaced by a patch piece or welding. I'm also wondering if it's even worth considering slitting the bubble and injecting some epoxy and clamping.

How old are the skis?

Is there a chance the bases are thin from grinding?

I guess by screwed I meant are the skis done. In other words, is it just going to keep re-appearing.

The bubble actually re-adhered without me slitting it or removing any base. It re-adhered using heat, some tools, etc. Once the wax cooled and I scraped the skis, I could not feel or see any bump, so I was actually pretty happy with the way it re-adhered.

This is the end of my second season on the skis. They have never been ground.

Thanks again for any input!

Sounds like a bad batch of epoxy. They are done.

Sounds like it was a pretty small area.

Just ski them. What's the worst that could happen? If it becomes a problem fix em or have em fixed.

What ski was this?

I probably wouldn't worry about it, but it's not a good sign. That should not be happening.

It certainly reduces confidence in the ski and I'd want to get on them to see how they hold up. Hard to say whether or not it's an isolated issue that is easily fixable or a bigger issue and the skis are trashed with out some time and mileage.

Some would see it as an excuse for a new pair and demote those to rock skis or back-ups. I'd look at it as a project to see if I could fix 'em and extend their life, to avoid the dumpster. YMMV

That's my plan, really. But I am leaving tomorrow morning for a week trip and I wasn't going to pack them and fly with them if the prevailing opinion was that there was no way they were going to be okay...even on a short term basis. At this point, they are packed and I will just keep my fingers crossed. If they last through this trip, it will give me an excuse to be thinking about picking up new boards at the end of this season.

The ski is the 05/06 Line Prophet 80. I had heard of some durability issues with them when I bought them, but until last night had never had any. I also picked them up at the time for $200, so either way I got my monies worth. Quite honestly, I love the way they ski and will be sad if they are shot.

Again, thanks all.

Is the bubble under a binding screw location?

I am not at home right now to check...but if it isn't, it would have to be darn close. I didn't even think of that last night, but just knowing about where the bubble was, it would be in that area, yes.

Then this has nothing to do with the ski, and everything to do with the length of the screws used to install the binding.....

Oh, I was actually thinking of the pre-drilled holes...I thought that was what Ghost was getting at.

The Prophet from that year was pre-drilled with holes for the Line Reactor binding. But that's not what I have mounted on the ski.

When I get home this evening, I will check to see exactly where the bubble was....in relation to both the binding screws and the pre-drilled holes.

What I'm saying is that without seeing the ski, you can't say it's hosed. You're awfully quick in pumping to that conclusion.

I know what delam-ing is. I just can't see why someone who knows so much about skis doesn't try a simple attempt at repairing first, and crying wolf later.

Every time I've bothered to fix down the first, second, third, fourth bubbles (and the ones next to the edges are a real PITA, particularly if the bases are thin enough that there isn't really a good way to get them flat again after the epoxy injection) it has just continued to come apart elsewhere, and yes I have left an entire 180cm base in the snow.

If his bases aren't worn to the thickness of, oh, 2 x milk jug, there's a fair bit more hope for the durability of any repairs, because a bubble (next the edges, say) won't rip and tear.

Which is why I asked.

I'd probably fix 'em, but I'm silly that way.

Well, from the sounds of it, you may want to take a *CHANCE* that they might be warrant-able (is that a word???). Take them to a dealer - who knows?
post #19 of 24
Don't worry about it.

I bubbled the bases on both my old AX3's in a number of places along the edge. Close to 20-30 spots per ski. They skied fine.

I got the metal edge to hot and the heat transfered under the p-tex through the metal edge.

Just makes it hard to scrape the wax off.

IMO people worry to much about perfect bases.

TOTALLY agree. Ski in MT for a while, and you'll never care again. The P-tex gnomes need to eat too.

For those who helped with their insights, I figured I should post a follow up.

Returned Saturday night from 6 days of skiing. The base of the ski with said bubble was fine all week. I don't think I posted this earlier...the bubble actually was not under a binding screw or the pre-drilled reactor holes.

Ironically, mid week when landing a jump only a little sketch, I partially delaminated one of my tips. A very nice tech fixed it overnight. But this would lead me to believe that it is possible that the "durability" issues I have heard of with Line are true and that may go a long way to explaining the bubble. I landed pretty solid, only with one tip (the one that ended up delamed) slightly on top of the other (ie tips slightly crossed whilst landing). So, now I really have an excuse to look for new boards.

Anyways, thanks again to all for their help.

I had an out of warranty bubbled pair of skis when I was a kid, and I seem to recall a manufacturer service dept. quoted me a price to straight up replace the entire base. Quite expensive, something like 150 bucks a ski, but I haven't thought of it in many years and can't say I've heard of anyone replacing an entire base.

red SCXs , Karhu/Trak XCDs, and, if it counts, glue-down base overlays on some Floskis with the internal oil channels. Greek meal with side salad, each time.


Wonder if that 150 was for a pass through an extruder machine? There was a link to one recently but they are far between.
