Cleanliness
Be sure to remove any dust or shards from the drilled hole. It is important to use clean screws, without any chunks
of material embedded from a previous mount. A screw with smooth threads ensures proper thread cutting when
you turn the screw in. It is also important to apply adequate downward pressure when starting the screw so the
threads cut immediately and don't spin and grind away the first engagement. Tapping the hole first is never a bad
practice regardless of metal or not. When mounting thinner skis that require the screws to be ground down shorter,
be extra careful to grind a slight taper and to avoid leaving any sharp burrs which will not cut a smooth thread into
the ski.
5.
Gluing and Screwing
We recommend using epoxy for the alpine heel mounts. Epoxy can increase your overall maximum pullout strength,
but most importantly acts as a buffer to decrease screw-loosening possibilities. This in turn can lead to a
degradation of the ski’s core and increase peak shock loads that will eventually result in the binding ripping out of
the ski. For alpine and alpine touring bindings, if you don’t prefer epoxy
, use simple wood glue to seal the hole and
lubricate the screw as it is being twisted in to help achieve suitable clamping force for given torque values.
Gluing allows a better screwage and avoids in one case that the binding becomes unscrewed, and in
another case this prevents water from penetrating into the ski. It is preferable to use fixation glue, and
on no account rubber glues.
Apply the glue in small quantities inside of the holes
Take the pieces to be screwed, put a little glue on the screw and screw with a screwdriver until the pieces
are well fixed on the ski. When the binding is fixed in place, make a 1/8 turn on each screw.
Nota:
If you are using a screwing machine regulate it on 5Nm maximum and always finish by last wrench by hand.
We recommend hand tightening each screw with a TLD-enabled hand posi-driver, making sure that each
screw goes directly and perpendicularly in and then doing a final torque spec twist on each screw.
RECAP OF THINGS NOT TO DO:
Don’t re
-use old screws that have crap plug in the threads. When you screw that into a new ski you are
cutting crappy threads into the core and compromising strength.
Cutting the screws is forbidden.
If you get a spinner and strip a hole, don’t half
-ass it
—
fix it right by putting an insert in.
Don’t reverse bend the ski when applying drilling pressure. Support it from beneath so that the screw hole
is perpendicular to the ski. Even a small amount of flex will change the angle and you'll lose full pullout
strength potential.
Don't grind out your initial hole threads by carelessly spinning the screw without downward applied
force.
