Asymmetrical Edge Bevels

post #1 of 14
Thread Starter 
After spending a couple days skidding turns on steep, bullet proof (western ice) groomers with a 2° side bevel, I'm going to change them to 3° so I can blame the bevel angles and not my technique. : While pondering the switch at high speed (instead of paying attention) I started thinking (always a danger):

As an experiment, what if I left two opposing edges 2° and changed the other opposing two to 3°? I'll probably do it anyway just for grins, as I'm not seeing any downside I can't manage while having a pair of skis with a different bevel on inside as outside. One bennie could be you could swap feet depending on conditions. Any obvious train wrecks I'm missing? I'll let you know from the ER how it goes. :

Sharpness on the inside foot is really helpful. You are putting a smaller load on it but you still want it to hook up cleanly. This is in part why it is important for the race kiddies to make sure all their edges are sharp, not just two. But whatever, I think it would be interesting for you to try and see if you can figure it out. The best would be if someone else did it for you and you attempted to figure out which was which blind.

Maybe instead of opposing edges you can do left or right edges...that'd be fun.

I have my AC4's (120 days) set at 1 & 3 my AC40's (30 days) still at 1 & 2, I haven't skied with both skis at the same time. Don't want to look any dorkyer then I do.

But during normal skiing they both feel the same. May be the 120 days and 1 & 3 work.

I'll bet you won't be able to tell the difference. You would have to run both edges over the same exact snow to may be feel anything different.

Well, if you ski with your feet together, may be...

Too late for me. I'll bump it a notch when one is tele and the other alpine.

Hopefully, I'll get a few runs in this afternoon. These are my Legend 8000's and I did go to a 3° for a while and back to the 2°. The 3° was clearly grippier and engaged faster while the 2° made for smoother transitions. It'll definitely be interesting to see on back to back runs or same run, how they 'really' feel.

Asymmetrical base bevels are next. It'd be interesting to find the best combo for steeps versus mellower.

Now that would be just wrong......actually, talk about side to side comparisons...hmmmmm. Too late for this round.

Too fun this afternoon with hero corn snow, no one around and high speed cruisers and very soft bumps.

Not the best conditions for optimal testing and there was probably a little placebo affect, but it definitely was easier to 'get a grip' where there was still some very firm base. I wouldn't call it life changing, but definitely substantial enough to be worth pursing further. The asymmetry was not an issue in these conditions. I can certainly be lazier, getting on an edge with the 3° and still feather easily with more grip to gain if needed, though the 2° still feels smoother at this point with less to gain.

I do the samething on my seths to keep them edgeable on hardpack, but still buttery smooth in powder.

Inside edge are kept a razor sharp(touched up every couple days) at 1 base and 2 side while the outside edges are kept kinda of dull and only 1 and 1.

easy to do on this ski becasue the graphic keeps them lined up

Ever thought of going to 2/1 on the outside edges?


PS speaking of wacky tune jobs if anyone can help me figger out a base scraper for these:

it would be much appreciated.

Bush, what advantages with the 1° side bevel in soft snow?

Comprex, why the 2:1? Powder and soft? BC the 2° base is not uncommon.

What about a 'shored up' contour gauge for those WTFunk skis?

(Lightly loaded?) stiff tip ski in spring conditions it could slow down hooking. (Did a pair of SCXs once with 6 degree outside bases)

Yeah, reading up on marine hull fairing at the moment, trouble is most of that is done with negative blocks or battens and sandpaper, no countour scraping really. If it was a single convex base curve I'd be ok, but it changes along the length. Fortunately and unlike the Praxis, the edges are only present along the lower section.

1) Spray or liquid wax?
2) Iron & fiberlene?
3) Roto brush with brass or steel?

useless except for megathick layers that hide the curvature changes.

I was trying to find something like this:

that has an inside, preferably compound, curve.

Assume I'm terrible at cutting tool steel; filing is out and grinding likely to wreck the temper.

I checked out cabinet scrapers thinking similarly. Why not cut out a shallow arc in a plexi-scraper? Jig saw then file/sand/rasp/drum sand......

Bode was said to have had his tech prepare one ski different from the other regarding the side bevel.

The "break of the hill" in a few critical turns was the deciding factor.

He won. There is some logic .... unique and specific; not universal but it does play out.

Yuki,
I'm pretty sure that was for one particular race only, where the course traverses the lay of the hill more than usual. The intent was to have a more powerful carve/edge in turning one direction, and "softer" edges in the other.
