Need help -> Fischer Motive C 84 Top Sheet Splintering Away

post #1 of 10
Thread Starter 

 Love this ski and have been using it  in difficult east cost ice/hard crud/ungroomed/natural bumps  where lots of speed control is required {brushing/scrubbing/smearing edge...etc} . The problem started quickly when the  top  'clear coat' was breached followed by lifting/splintering of carbon layer . Does anybody have any  suggestions on how I can save or extend the life of these skis by a few more years? I've been cutting away the splintered carbon sections and trying to protect with epoxy layer{you can see residue} but epoxy wears away. For now I use a strong fiber glass tape to protect edges and  replace it after each outing.  A few days  I skied without tape and degradation was expedited. See photo 2 for newest lift. Photo 1 shows where I cut away  splintered carbon and area seems stable now. 

 

Fischer, if you are reading I would be happy to send you my old skis for a replacement equivalent...I would be willing to pay cost! I also own a pair of Motive 88 for softer snow conditions and they are holding up very well. The 84s have been skied around 20 times and ski was purchased on-line  in late 2012. Both myself and brother n law are big fans of fischer skis and are a bit mystified by this general defect.  Thanks for any suggestions.

In the future you need to round off the ski top sheet.  In other words the sidewall of the ski. Smooth it into a much rounder shape. That prevents it from being so cut up when you bang your skis together.  From the photos it seems you never did that.  Also round the ski edges at the shovel so when the shovel hits the other ski it doesn't do so much damage.  This is important for sandwich skis.   I think you need to say good bye to those and start over again.

I've never heard of anyone doing this before?   Do you use a router or just some sand paper and do it by hand? 

 

I have some 2010 K2 EXT skis which I love but I jump a lot and each time I crash I get a 'chip' on the inside edge of the top of the ski.   These are merely visual defects on my skis however at this point.

focker ..  good tip. I see Volkl and some other manufacturers doing this. I  am determined to get another few years with tape and glue!

You use a file.  Start with something aggressive first such as a panzar file, the move to a finer file, then to sandpaper.  I will make a video of the process in the future.   It makes a huge difference.

I don't think I have one to do in my shop now, but maybe I do.  If so I just might do a video today as the Mt. is having strong wind with snow.  Take care.

You need a strong epoxy and use some clamps with wood against the top and bottom.  Then allow to cure while clamped down.

Will keep my eye open for your video.

If I can do one today, I'll start by posting it here for you.  It will help you to be able to see the process.  Then you can go to town on those skis after you epoxy them back together.

Okay dminus, I have the video going up now.  It's going to be a while as it is long as all my tuning videos are.  I will show three examples in the very comprehensive lesson.  When you watch it your going to need some popcorn or something, because it's 45 minutes long. 

 

Get ready.  Coming soon to a site near you!  "Sandwich Ski Sidewall Preparation"

Okay here you go!  Get your popcorn and beer or whatever before you start!
