Progressive base bevel?

post #1 of 8
Thread Starter 

Planning on staying at a 1 base bevel until I need a grind.  But I've read some on progressive base bevels at the tips and tails instead of de-tuning.

 

Would I go up to a 2?  And where do I start that increase or how far down towards the center of the ski?

 

Thanks for all your help so far.

My base bevel is SLIGHTLY more beveled the last six inches at the toe on one pair of skis. Specifically, using a base bevel guide, I exerted pressure forward of the wide section of the ski and polished that base edge. But it was the same guide, a 1, that I use normally when I remove dings. That slight easing of the bevel kept the edge sharp but made the ski less squirrelly on hard pack. Understand, I tried it a day, polished a bit off that night, tried again, until the skis suddenly flipped from spooky to wonderful. But I doubt if they are even 1.5. Since then I haven't touched the base, but I still sharpen the side.

If you're skiing hardpack or off piste, don't detune. Your skis will perform worse. 1 degree base bevel is plenty (I'd say too much, having switched to 0.5 and enjoying the performance feeling).

 

If you're in the park, you can detune.

Do Not de-tune a shaped ski.

 

I guess everyone hasn't learned that yet...

 

IMO if you have to adjust the bevel, there is some other issue going on.

 

99% of the skiers are on a 1* base bevel.

No, never learned that about shaped skiis.  Still stuck in straight ski days.  I could have sworn I saw techs de tuning shaped skiis when I was watching some videos on techniques.  Good to know.

If you don't keep an eye on them, many techs WILL detune shaped skis. I always make a point of telling them not to, because some of them didn't get the memo.

Ditto.

 

I usually set my own edge angles after a base grind.  Sometimes, if it's a good shop that I'm used to, I'll let them do it.  But when I do, I make sure my specs are crystal clear & on the work ticket.  Plus, I apply a strip of 2" wide bright orange tape on top of each ski & write "Grind flat then set: side angle=3, base angle=1.   DO NOT DE-TUNE!!".

Yep, a sharp shaped ski tip to tail will engage the edge quickly, if you have great fitting boots, Do you ?

 

I can just about think turn the ski is there. It really is that quick and smooth, little to no effort.
