Going from 1* to 2* side edge bevel...Good or Bad idea...?

post #1 of 14
Thread Starter 
I am going to start doing the tune ups on the families skis and boards...

I have read up as much as I could get my hands on here in the tuning forum...

I am pretty good with tools, I am a amateur wood worker and was a machinist for several years...

I would like to change the side edge bevel on my head im72's from 1* to 2*...

I am looking to improve the edge bite and carving ability on these skis...

Would this cause the skis to become to edgy or would it give me the performance improvement i am looking for...

Sounds like a good plan. If you like the results, you can go to 3 degrees next time.

Got to three. You will never go back.

There really isn't any benefit to going less than 2 imo. I'm at 1 base and 3 side. It won't make your skis hookey. The hookey edges come from going lower on your base bevel - to maybe .5

Sounded good to me too...

I look forward to doing this and giving them a whirl on the mountain...

I am going to try 2* first...

Then see if I want to go further than that...

Sharpen all the way around the curve of the tip & tail. If you'll be on hard snow, go 3°. When you next get the bases stone ground, tell the shop to do 0.7°, or maybe 0.5° on the base edges with the tip and tail area beveled to 1° by yourself if they feel grabby. You can easily add more base edge bevel yourself if you need it. Dry Colorado snow doesn't need 1° on the base, IMO.

OK...
I don't want this to come across as a stupid question, but here goes...
When people talk about the side bevel, are they talking about the side bevel angle in relation to the base or base bevel.

When I use my edge tool set at 2*, I am putting the edge at 2* compared to the base , which is where the tool rests against, assuming my base bevel is 1*, that would make my edge bevel really 1* compared to the base bevel.

Am I confusing everything, or over thinking.

I am assuming I just trust the angle that my edge tool sets up for and just go from there, just dial up 2* edge angle and go to work...

Essentially correct, but you would be making your edge bevel really 1* (past 90) compared to the base edge bevel (and however minute an area the base might be beveled in past the edge); it would be at 2* compared to the (assuming flat) rest of the base. But the two edge bevel angles are what affect the ski performance for the most part.

Thanks...

So when people talk about getting the skis set up to a 1* base 2* side bevel. they are setting up the angles measured from the base of the ski...

From the Measuring Edge Bevels entry in our Tuning Blog:

Quote:
(Note: the side edge angles 0, 1, 2, 3, 4, etc are the angles cut inward from the side edge relative to a 90° degree corner. Thus, the European standard is 90, 89, 88, 87, etc, while SVST/US standard is the dedicated edge guide designation to create the side edge bevel, 90, 91, 92, 93, 94, etc.)

Base bevels are simpler in that they are designated relative to flat: 0, 0.5, 0.7, 1.5, 2, etc....

The most common bevel angles are 1° base bevel & 3° side bevel. Designations always should include base bevel angle first, followed by side edge angle: 1:3 for 1° BB & 3°SB, for example.)



Additionally, here's a detail of changing from a 2 to 3° side edge, which is basically the same for going from a 1 to a 2°:

Thanks for helping clear all of that up...

I have tuned the edges to 2* using my multi angle edge tool...did my wifes skis also...

I cant believe how much better they look compared to when a local Big Chain shop did them on a machine...

I went from 1*/1* to 1*/2* on both of them...

I cant wait to how they ski, hopefully better...

Glad to help. Some of this is confusing to get your head around some of the concepts.

FWIW, I tweaked the graphic and you may need to refresh or clear cache to see the changes.

Personally, I like the smoother 2° side bevel edge transitions for general/all-mountain skiing and softer snows.

Thanks for your help...
I was over thinking the angle stuff...
Comes with being an analyst for a living and having been a machinist for several years...
I finished off the edges today with some diamond stones, my wife looked at them and wanted to know when can we go skiing...
Again the difference in what the edges look like now vs what they looked like after being put through a machine...is massive...
