Dynastar WC Top Sheet De-lamination (w/ Pictures!)

post #1 of 8
Thread Starter 

Skied <20 times, bases always kept apart by bands, skis hand tuned with fine file and/or diamond stones every other time skied, this happened:

It doesn't look that bad, but I don't want it to get worse.  Any thoughts about sending it back to Dynastar?

Is that a topsheet cut by the other edge scraping it,  or lifted up (delammed) due to adhesion failure,  or shattered apart by the impact shock of slapping down on ice. If the adhesion has failed in the 'sandwich', send them back in the first year.

That doesn't look like "delamination" to me but hard to say for sure based on the photos.  I actually worked in a company that made laminate products and when something delaminates it tends to peel up in tact and flap around where it used to be glued down with contact cement.  Those photos seem to show chips in the top fiberglass all along the edge of the ski.  Those usually happen from the skis banging together. But, hey, if you're done with them send them in.  It is worth a try as sometimes they just prefer to send you something to make you happy rather than squabble about it.th_dunno-1[1].gif

^^^ I've had two skis delaminate in my life, one dramatically, one barely. One was a (very) old Head, one was a recent indie. This is not delamination. This is a little chipping/erosion from another hard surface (edges?). FWIW, Dynastar makes quality stuff in my experience.

Yeah I originally thought they were banging together or something when the first spots started to show the second day I skied them.  These were on the tails though, and I decided to just sand and seal the spots, and decided to use that ski case I have had in my basement for a while.  Smart idea I know!  Anyways I smaller spots curled up, then I noticed this.  It's about 3 inches long and directly in front of the binding on my left outside edge.  This means that this section of my ski couldn't have hit my other ski, except during a race when I switch to my race edge (and I haven't fallen during a race on these skis all year).  I'm not sure if "de-lamination" is the right word to describe what this is, but it doesn't seem normal confused.gif

yeah looks like delam, especially the 'end' of that section

 

who mounted the bindings?

they go deep enough on drill/screw depth?

 

not familiar with the ski/cosmetic - these metal topsheet? if so, were the drill holes tapped and countersunk appropriate to materials?

 is there visible cratering under the binding mount?

heavy cratering can pull up/relieve the topsheet from what it's glued to... and start the delam process.

 

if they were properly mounted then it should be a non-brainer on factory replacement - which can be a glacially slow process

 

you got another pr to ski on?

I think it looks normal for a race ski. If it still skis fine, keep on using it. It's a tool for going fast. Nobody is going to try and warranty the paint on a 911 GT Cup car.

They come with a race plate already on, and holes pre-drilled in the plate.  All you have to do is screw in a Rossi/Look binding and you're set to go.  Even so I had one of our top shop techs mount it, just so that I didn't mess it up.  Nothing under the binding, the delam starts right in front of the binding, but I'm sure if I keep skiing it, it will spread under.  Luckily I'm all set for the rest of the year, only real races are SL's but it's still a pain to deal with Dynastar and ship them in and everything.

I usually wouldn't care, but this years race stock is designed oddly -- It's pretty much a piece of paper with graphics on it, and then a piece of laminate over top of that.  If the laminate comes off the graphics under it absorbs water fairly quickly and will become distorted, and worse, expand.  So it skis fine for now, but it won't if it stays this way.  If someone messed up and the paint on my [imaginary] 911 GT and it started to flake after I drove it 15 times, I would call and get a new one.
