Vertical Sidewall with Flush Edge How to Tune?

post #1 of 9
Thread Starter 

Good Afternoon Bears

I just brought home my first ever pair of all mountain skis, K2 EXT. I bought them to use in Lake Louise next winter. All of my other skis have edges that are raised from the sidewall to allow sharpening. These skis have smooth sidewalls (no raised edge). I have to conclude that these skis can’t (shouldn’t) be sharpened. I guess sharp edges aren’t as important in the Rockies as they are in the Adirondacks. Do I need to put an edge on these bad boys? If so How?

Always nice to know someone is getting new skis.  Hopefully I'll join you in that sooner than later.  If your sidewall won't allow you to set your desired side edge angle, then you'll need to use a sidewall planer that you can adjust to plane off enough sidewall material to get to your edge properly.  When shops tune with machines, that portion of the sidewall will be ground off right along with the edge material down to your desired  side bevel.  As far as I know, edges are just as important here in the Rockies, just not for the ice I only hear about in the east.  Have fun with your new skis wherever they take you!

Thanks for the reply!

I have a first rate side planer and I usually take 1-2 mm off above the edge on my race skis to grab 3 degrees of side bevel. Are the side walls thicker on these type of skis to accomodate that?

Hi Speeder,

 

Take a look at this video - it's for a ski that's been tuned down to a flush sidewall, but the principle is the same:

Speeder,

That video is a great tutorial.  It pretty much says it all.  I need to find me one of those notched sidewall file/cutter tool. The edge on that ski will be gone before the sidewall is.  I don't know if your sidewall is thicker than your race skis, but it should be plenty thick to accommodate any new angles you'll put on your all-mountain skis.  It's usually more of a question of how stiff is the plastic (i.e. ABS -softer or UHMWP - harder) instead of it's thickness to accommodate tuning.  If I'm off base on this someone will let you know, but look at the link below and note the thickness of all of those sidewalls.

Thanks Guys, this is great info, I have a pair of Fischer slalom skis I was about to retire that will benefit from that treatment. That sidewall scraper looks like it was made from a file, or is it a retail piece? My tuning bench set up is pretty complete and I can and will do this or something similar to my vertical wall skis but I can't imagine 99% of the skiing public (who aren't racers)  would be wiling to or have the tools or the inclination to remove that much material and reconture the topsheets etc. Does "twin tip" John Q Public just get sharpened by grinding once a season at a shop?

Speeder, Yes, I think that is exactly what many do.  So much so that I made a portable shop to try be available for tunes on the go.  We'll see if I can entice some to tune a little more often, maybe even defray some tool and equipment costs of my own.  wishful thinking

Thanks much to coregguy and Start Hause for showing me the way,  I have no issues with shaving all mountain sidewall. 

I wonder though what is the purpose of leaving the sidewall flush from the factory?

Nice video.  Bad season at Tahoe when a pair of skis had to be resharpened enough that they lost their sidewall ledge.
