Homemade DIN torque tester for bindings?

post #1 of 6
Thread Starter 

Has anyone made their own gizmo to test the release torque of bindings to make sure it matches the expected DIN settings?

 

I imagine it ought to be possible to make something suitable with a torque wrench.  For example, to test the twisting torque in the horizontal plane required to make the binding release, you could have a piece of wood that goes into the boot, attached to a torque wrench via an extension shaft.  Then you just twist until the binding pops. 

 

To test upwards release on toe or heel would be a bit more complicated, but still do-able.

 

If anyone has dabbled in this area, I'd be very interested in details, pics, etc.

 

P.S.  In case anyone is wondering why I'd be crazy enough to want to do something like this myself instead of simply taking them to a shop, the reasons are:

  1)  I usually trust something I do more than the same thing done by someone else; and

  2)  I *like* making/doing things tongue.gif

Why bother when you can buy one remanufactured for under $4,000? biggrin.gif

Just click in to your bindings and try twisting your legs out of them, both left and right.  Also be sure that you can pop up each heel piece without hyper extending a knee. It's always better to let a real tech familiar with the gear and testing tools do it, but for God's sake if you do decide to go DIY, be sure you can turn the toes and pop the heels easily enough before actually skiing them.

Let me guess....80% of the $4,000 goes to the manufacturer's liability insurance, and the rest is split between profit and the cost of the materials biggrin.gif  And, hey, you can get a pad of 50 Post-Accident Inspection Reports for only $40 more! tongue.gif

Not hard to make at all, with modern strain gages available all of the test could easily be done even with computer interface if one feels so inclined.

 

Would I make it for anyone else or use it to test analyze somebody else's bindings, NO.  The prospect of being sued, just doesn't seem like a good idea.

Way back in ancient times a Gordon Lipe made a consumer binding checker called the Lipe Release Check. I have one. It measured the force to push the boot out of the toe piece.
