Advice needed for bindings constantly being ripped from the ski

[jfp]

Wanted to get some answers here. A FFriend of mine who is 240 lbs keeps tearing his bindings off his skis. He insists on marker jester pros, and has them on all his skis, bentchetler, Nordica bushywayne, any advice on bolting the bindings down in a stronger way? Any advice at all?

does he get them all mounted at the same shop?

Get skis with plenty of metal in them.

Throw away the standard screws and mount with something like Quiver Killers or Binding Freedom inserts from the get-go. Pullout strength is way higher than a normal screw.

Thanks, I've personally never heard of either of those? Are those just special screws? I'll look into it and yeah they are all mounted at the same shop.

I would consider finding a burly ski that is not meant to be lightweight and has a solid wood core and perhaps metal as well...J Skis talks about exactly that type of construction

They're a much larger metal fitting that you install into the ski first, then the binding is attached with machine screws.

The pullout strength of the way larger fitting significantly higher than a normal screw, and the machine screws that go into the inserts are unbelievably strong. An M5 high-tensile screw should be able to take about 800kg of load so I would say a 240lb skier over 16 of them should be ok.

Thanks, I will look into that, he usually rides a fat 120+ waist in 190ish length range. Any other ski suggestions for burliness?

Quiver Killers or even heli-coils will help with added purchase in the ski. A ski with some metal in it would add an additional layer of bite too. Maybe try a different shop too, they may be spinning a screw or three and that def wouldnt be helping screw retention.

heli-coils should do the trick ^ also maybe upgrade to a pivot binding so he isn't just ripping the binding up and out of the ski, i finally upgraded to the Fks and I'm never going back to Markers, the weight difference doesn't effect the way the ski rides and I've never felt so safe ejecting from my skis

I've seen tear-outs in skis with metal in them (Blizzard Bodacious, super 7 come to mind first). The metal laminate usually peels off the core material, and the binding stays connected in it while the rest of the ski breaks or just megadelams.

Look for skis with maple stringers in the core and fiberglass binding mats.

This is true. My friend just delam'd a Cochise down the entire length of the ski, basically pulled the layers apart instead of ripping the binding out. Was damn impressive actually. But at least the binding stayed attached to the ski I guess...
