Just got bindings mounted in shop...

post #1 of 23
Thread Starter 

Hey, got the skis home and took a closer look, only to find the heel end of the binding on each ski is noticeably over to the left on both of my line Prophet 115s. Those familiar with the Prophet will know that it has a metal top sheet 'skeleton'. Each heel binding is close to the left edge of the skeleton on both skis. Will this affect the performance of the skis? Should I take them back and query it?

 

Many thanks, Robbie

I have a pair of Prophet 115s in the garage and believe that the die-cut metal just under the topsheet is symmetrical when comparing the left and right sides. It sounds like your bindings were not centered between the ski edges. Is this the case?

Yep, you got it. It appeared to only be the heel pieces, but on even closer inspection, the toe piece on one of the skis os mounted over to the right.

Can you measure and post the amount of offset?

Hey, they're 3mm of centre to the right on the heels and about 2mm of to the left on the toe.

Well, I commend you for being able to notice a 2-3 mm offset - that's not very big.  I'm thinking it isn't going to make a noticeable difference in the skiing - wear on your boots could probably make more of a difference than that.  But here's one thing you can do: go talk to the shop and see what they think.  Talk with a manager or owner and if they don't think it's a big deal, let them know that you're going to ski them and that you'll be back expecting redress if it does make a difference to you.  

 

Or you can just insist that they replace the skis, but 2-3 mm doesn't seem that big a deal to me, at least without skiing them.  FWIW, it will probably seem like a big difference to someone here though.  

 

I'm going to resist going out to the gear pile to measure the mounts on my skis to see if any of them are off by 2-3 mm.

It may be more noticeable by sight due to the symmetrical metal top sheet, really just wondering if it would affect skiing performance, and if it's worth following up. I guess I won't personally know until I get them on some snow.

 

Many thanks

It is worth following up.

 

If you are going to do something about it, do it now while the ski is still 'new'. In order for the shop to 'make this right' they may have to replace the ski, if you have used them this will be more complicated, be proactive and bring them back before you ski them. Take them back and let them see what is wrong and if they are a descent shop they will work with you to make sure your skis are 'right'.

FWIW, a 5mm (.5cm) offset on a 300mm length between toe and heel equates to just a skootch under 1°.

 

How did you measure from your edges to determine an accurate centerline? If it helps, print this and see how it compares:

do not rely on any visual coming from the cosmetic or elements in or attached to the ski.

 

when bindings are mounted the jig is normally centering the bindings to the center of the base edges, not the center of the top sheet.

 

to determine center of the ski you need to be measuring from edge to edge on the base side, not the top sheet.

 

your bindings may be mounted off center. it is not unusual for a jig to be "off" due to low manufacturing specs, poor quality control, or some form of damage to the jig that takes place with use. it could get dropped and the feet could get tweaked, or sometimes a shop will lose one of the four rubber feet that contact the ski edges.a good binding tech should be checking this every time that they mount a ski.

Hey, I measured from the edge of the top sheet to a specific point on each side of the heel pieces and subtracted to determine how much offset there is. The same was done with toe pieces.

 

The break is making contact with the edge on the right side of each ski, but not the left side as well.

 

I'll give the shop a ring tomorrow and let them know my findings.

Ya they mounted them crooked. Trust me that will drive you nuts every time you look at them. I mounted my my prophets with a paper template and got them with in .02mm. I bet if you you measure them they are off the exact amount on each side. If you got the skis new from there shop tell them you want a new pair mounted correct. They will then tell you we will fix them. Ok How loosen them up and force them over. Move them back or forward 1cm and drill more holes in my new skis. Wrong. Give me my money back or a new set of sticks mounted right.

Post a picture up and you'll probably get more specific feedback.  However, knowing they are off center would personally drive me crazy, especially on new boards.

I wonder if the rubber feet on their jig had fallen off (and gotten turned around when put back on?).

I have to agree with Bob, even after looking at your picture.  That mount is not likely to be noticeable in your skiing. 

Ski 'em and enjoy 'em!

Looking at the picture, yeah, probably not such a big deal, so long as the break doesn't catch the edge of the ski on the right side there.

Sweet, thanks for the feed back guys, I look forward to skiing them! I'm primarily a snow boarder and these are the first new skis I've owned, only owned a second hand pair before. It stuck out to me on first glance, better to be sure.

 

Thanks again, Robbie

Sometimes they start to slide a little off the arms of the jig, or a little detritus can get on 'em or what starthaus said upthread.

 

To Mr. Churches: when you go into the shop to talk to them, have them jigger that brake arm a little bit to clear the edge.  They should have noticed that - I have to say that I'm not entirely impressed with that shop.

Whatever you decide it's still worth mentioning this to the store, if only so they can have a look at their jig (or whatever went wrong) to prevent the next pair from being off.

post #21 of 23

I would still say something to the shop. I wonder if you'll feel it much on that ski?

If it is 1 degree off as someone calculated you might feel it. And both skis are off the same amount to the right?

It's a shame they didn't abduct the skis.

 

 

post #22 of 23

it would have to be 5mm off to be ~1 degree. his are not that much off.

 

post #23 of 23

You might want to bend those brake arms out a bit, they look pretty tight...

They could actually re-drill and use Helicoils to change the position of the binding screws. Wouldn't be difficult.

 


edit: Unless it's a base grind, I do all work myself. Shops are in too much of a hurry.
