second bevel on a pair of skis

post #1 of 15
Thread Starter 

Hi guys, 

 

After tuning my skis, the side edge looked like it was "stepped". It looked something like this cross-section: 

----------------------

                      |
                       \   <--sidewall
                        \_   
                          |
                         _|  <--edge

  ptex                 edge's second bevel
   

 

  

I ended up taking back the side edge to remove that second bevel. However, I'm really confused about how this could happen. It wasn't just dulled, but rather like a cut-out had been made the entire length of the ski about the thickness of a fingernail (so just a tiny sliver)... it also appeared to only be on one edge of one ski. Any thoughts on what I might have done to cause this?

Was the ski machine tuned?

Somebody effed up somehow!  :eek

Can't envision this happening with a hand tune. But it sounds like you did the tuning? I'm thinking it somehow involved a tune of the base edge, which we generally wouldn't do, possibly using a guide that does two edges at once? I think I have some old tools that might do that.. I never use them, just was given them at various times. Will look to see if I have a pic of one, but easier for you to give us more details.

Beer. Lot's of it.

Yup, I believe I did the tuning. Not sure what I could have done. Didn't touch the base edge. Possibly the file tang was catching on something when filing, I'm not sure... Oh well, derp

Maybe something like a chip off a stone caught under the file, so it stuck out beyond the guide?  I don't think an edge shaving would be hard enough to cut more edge.

This is the whole way down the ski? Aside from a metal curl being caught between the guide and the ski, seems more like a machine-caused problem. And my metal curls usually are shed away from the base. Did you look at the guide?

I, too, can't imagine a metal curl causing visible damage the whole length, I'd expect it to fragment before that happened.

Hey there, I genuinely have no idea how I could have done it. The "machine" was just a side edge guide, plus a file and some stones. 

 

I've repaired it by just continually filing until I brought the edge fully flush. No problem now. Strange that I could have broken it!

If you are old enough, blame it on age and Alzheimer's (actually any age will do, but if you are really young brush some gray paint in the hair to pull it off convincingly) ;).

Just want to get the proper technique. The pull off is in reference to the hair, right? :rolleyes

Maybe there was an internal defect in the metal and it just chipped off under pressure of filing? Can't think of how it's otherwise possible, I don't think you can do it intentionally if you tried.

Most importantly, how did it ski? Are you on to a new tuning style? 

 

We're sure to hear: "1/2, 3, 91, 2 is so superior to 1, 2, 89, 3!"

Nice etch-a-sketch picture you made there, Metaphor.
