Contact 4x4 bevels?

post #1 of 9
Thread Starter 
I finally felt there was enough snow to ski my new Contact 4x4s.It was quite firm hardpack, also known "ice" (northern  Rockies style.)
Unfortunately, I found it difficult to get the tails to release smoothly.
I have also found that when carving, I can feel an inconsistent grip as I carve from the front 1/3 of the ski through the midpoint.
I hit the edges with my gummi stone; 3-4 passes on the full edge length and harder on the last six inches, which seemed to improve the performance but I don't believe this is the entire answer.
Should I look at deviating from the standard Dynastar recommendations?

I had a similar problem with the tails of my Stockli VXLs.(I had other good skiers ski them and they felt the same problem.) I had just had them tuned and they were set at the recommended 1/1 bevels. I also have a pair of Stockli XXLs(1/1) and had had no problem with them.
So I checked with "The Waxroom" in Ketchum/Sun Valley(a Stockli dealer and a great tuning shop) and they said they had noticed the effect with the VXL and were tuning them with a 2 degree base bevel and they skied well. I then had mine tuned with 1-1/2 bevel and they ski nicely.

Thanks for any suggestions!

Thank You.

Your Dynastar Contact 4x4s are a stiff carving ski with some 'All Mountain' versatility. I would first check the factory tune to determine your actual base and side bevels. Also check to see if the bases are actually flat. I've purchased several new skis lately,still in factory wrappers ( Head and Dynastar) that really needed a New Ski Tune-up as they were way off. A base bevel exceeding 1 degree on these carving skis would really reduce there ability to hold an edge. I personally enjoy a .5 to .7 base bevel for quicker edge change on groomers. A 3 degree side bevel will greatly enhance edge hold.(With little or no change in Soft Snow Performance). Be sure to plane for sidewall clearance. My newest Dynastar Contact Cross Tis needed a lot of sidewall removal in order to increase the side bevel to 3 degrees. I sharpen tip to tail and do not dull the ends with a gummy stone..YMMV.

Thank you! I was hoping that new skis would have a fairly decent tune but apparently that is not the case.

You choose:
A)  You have a hanging bur (do a search).

B)  You are trying to ski a carving ski designed to hold onto a turn as if it were a park ski designed to spin on a dime, and the ones you demoed had all the performance and grip tenacity beveled and dulled out of them.

If A), sharpen to razor sharp tip to tail, first base then side, and then run gummy stone lightly along BOTTOM edge only.  Recheck sharpness, and lightly touch up side edge as required.

If B), take a lesson from someone who can arc-edge-locked turns on hardpack, what you call ice out west; once you learn how to arc edge-locked turns, there's no going back, and no worries about releasing, just anticipation about engaging the new edges.

I was finally able to get my Contact 4x4s to a good shop and have the bevels checked. I don't know what their "state" was but they re-ground them to 1 and 2 and they ski beautifully.

It would be fun to ski with some of the people that question my ability to carve turn and work a ski, as the answer to my problem.
