Edge tuning and de-tuning 5 point sidecut/rockered skis.

post #1 of 7
Thread Starter 

What's the current thinking on this? Particularly the area of edge that is tapered toward the tip or tail, or rockered?

 

My S7 is dulled with a 200 diamond from a few centimeters past the point it begins to taper at tip or tail. Why? Because it was there? No, that doesn't work here.

 

Thanks in advance for the help. I took my best guess, now let's see what I should have done.

I usually only ski my S7s in soft deep snow, so...the edge tune doesn't seem to matter much. I

usually sharpen them tip to tail. If edges seem to be an issue just carry a diamond and adjust/

detune as needed.smile.gif

Mine are also designated deep snow skis, so not the same tuning issues as someone skiing it for a daily driver. thanks.

I detuned all the rocker on my 5-point Keepers last year, but skied mostly deep snow with them, and they carved fine on the soft groomers.  Had the bases ground to flatten them at the end of last year and then just used them recently on some very stiff groomers and they were downright scary.  I thought the shop was just going to flatten the bottoms but they razorized the entire edge tip to tail.  I had to do some serious dulling again to get them to behave on the groomers.  The 5-point design results in sidecut going in every direction on the tip and tails, and if it's all sharp you'll be in for some interesting turns when you lay them over on hard snow.

What was you de-tuning process, MF?

 

A friend of mine went after his Cham 107's with a mill file, rounding the edge substantially in the tip taper section. He said that one should note that some skis now don't even have steel edge in that section, Salomon Rockers I think for one. So he put about a 1mm radius on the edge. Another guy watching said: AAAAaaack! you're ruining the ski. reply: this is not the first rocker I've skied on. reply: yeah, but....

 

So, opinions vary loudly.

 

Thanks for the input. First hand data is the best.

My skis have some camber, so I pressed them together, which results in lengthening the rocker about 5 more cm on the tip and tail.  I marked the end of the rocker with tape and then used a diamond edging file to lightly dull all the rockered edge and feathered it into the unrockered sections.  I skied them on hardpack with the file in my pocket and then dulled them a little more at a time until I liked the way they skied.  It seemed that dulling the tails had more of an effect on improving predictability than the tips.  It took some substantial dulling to make them work for me, but I would rather do it a little at a time because once the edge is gone it is not coming back.

 

I believe there is another school of thought on increasing the bevel on the rocker instead of dulling, but I have not messed with that.  My Keepers are for deep snow and not an everyday ski, so I am not too concerned with hardpack carving ability other than to get me back to the lift serviceably.
