improperly mounted bindings?

post #1 of 12
Thread Starter 
Hi,

I hope some of you will be able to give advice on the following situation.

We had a short (140-ish) pair of Fisher twin tips mounted with the Tyrolia SL 100 bindings in a local shop (bought them there). A few days later I happened to examen the installed bindings closely. The first thing to stand out was a raised rear corner of one of the heel pieces. It was about 1-1.5 mm away from the surface of the ski and the screw was visible between the binding and the ski surface. I then noticed that all of the binding pieces were clearly off center. We proceeded to take two (front + rear) binding pieces off of one ski (4 screws per binding piece). We found that the screw holes on one side were 1-1.5 mm closer to the edge then the screw holes on the other side, in other words the center of the binding was 0.5-0.75 mm away from the ski center (midpoint between edges). The depth of the screw holes varied between 7 (this is the hole that was too short for the screw resulting in a raised corner) and 9 mm. A screw in one hole appeared to have been overtightened - the thread made on the inside of the hole by the crew had been broken (was barely left) and the top of the ski right around the hole was pulled up in a wall-of-a-crater-like manner. There was no visible epoxy or glue inside the holes or on the screws. Everything was measured with calipers.

How (u)normal is this?
Should we use the skis as is?
Can this be fixed? e.i. drilling the short screw hole to proper length and adding glue/epoxy to all holes?
Does the above mean that bindings were mounted without a jig?
Should we not use the skis?
Should we return the skis?
Other comments?

Thanks All.

This is not good! The screw holes should be uniformly centered, 9mm deep, slightly countersunk, and glued. The binding should sit snuggly on the skis without being able to see between them. Take them back to where you bought them and have them replace the skis and mount the new ones for free. They should recognize the faulty work and help you out. The good news is that you supported your local shop rather using the internet for your gear-you would have been screwed!

DCNB,

This wouldn't happen with a system binding

Yes, indeed some system bindings do come from the factory without the "hostage plate" tightened down sufficiently. I'd say about one in three "hostage plates" are not torqued anywhere near the required 9Nm!

Standard mounted bindings vs. using a system binding/hostage plate is analogous to rack and pinion vs. power steering. Race cars don't have squishy power steering- for a good reason!

Pure BS alert.

Several hostage bindings have even been recalled by the CPSC...which is pretty damn sad.

Interesting to hear that Phil ... especially the setup in your signature being a flat mount binding (looks like a Mojo 15) drilled into an Elan M999

You do realize Phil was joking, right?

Not normal at all,

and you should definately take the skis back to the shop, show them the holes they mis-drilled and grab a new pair off the shelf - and hope they don't screw up again. They should of used a jig (nothing indicates a reason to not) so they probably didn't clamp it on properly. The old saying still applies, measure twice, drill once... I think your shop forgot that.

Here's an update.

We took the skis back (one with dismounted bindings).
Upon showing the shop owner our reasons for concern he agreed right away
to give us new skis for same price. The skis we got were different and not twin tips as the person who was to use them decided he/she did not need twin tips after all. The new bindings on new skis are mounted properly. The person who did the first mount was not the shop owner.

All ended well. Aren't you glad that you dealt with your local dealer, rather than the internet?
