Has anyone ever attempted using something like helicoil inserts to mount two different pairs of skis with one set of bindings so as to be able to move them frequently back and forth like Line's system? I'm thinking of this in terms of using my Naxo's on two different pairs of skis.
Im looking at the placements of a naxo and p14 and they dont seem to be overlapping at all.
So at least on that behalf that should be ok.
Any way to make sure the helicoils STAY IN THE SKIS?
Other than epoxy obviously.
Drilling oversize and running a sheet metal screw in to give epoxy more surface are to grab to, filling with epoxy, drilling for helicoil then inserting helicoil?
That's great. But what I am saying is, I want threaded holes for one set of bindings in two sets of skis that will stand being re-inserted into more times than a slut at a CU Football party.Quote:

I know that some people up here in skandi use those, but i have not heard any stories how they hold up.
Aren't the Crossplates rather expensive?
Last time i heard someone speaking about those they were 120-149euros (150-180$?) 2 binding plates and the baseplate.Quote:

I have tried a few different methods for ski binding swapping:
1. get some cutting board and t-nuts and mount as risers with both binding patterns on the board
2. get snowboard insert replacements and drill through your skis and re-weld bases (this is really not that great of an idea).
3. Get a machine shop to CNC it! (have not done this yet..but have the CAD)
In all cases you need to be really careful to get your binding pattern exact because you don't have much fudge room with machine bolts like you do with wood screw mounting. I used CAD to do my templates for Linken bindings and dynafits.
You can also do the first option with aluminum and just tap the binding pattern holes (just don't cross thread!) - I actually have a bunch of aluminium in 10mm if you are interested.
Also - I think doing the bindings with heli-coils is the worst of the options - helis are way to soft and have a lot of spin potential.
Yeah, I did consider that, but don't want to go quite that far. I think I will just be safe and either get another set of Naxo's for my next ski or stick with alpines on them. It was just a thought I wanted to ponder.
The cross plate 2.0 is your best option. http://www.telemark-pyrenees.com/sho...roducts_id=134
putting a Naxo on a riser will likely cause altitude sickness ;)Quote:

Not the kind you have to weld in from the other side; the kind that's a step up from a helicoil. You use an oversized bit to bore a hole, then drive the insert in with a special tool (or just a screwdriver). The brass inserts I'm thinking of are threaded both on the inside and outside; the outside threads are how you drive the insert into the oversized hole, and the inside threads guide the screw into the insert.
I had a pair of skis a few years ago with helicoils that i used with 3 diff bindings (alpine, AT, and tele). The bindings were mounted on plates with the same hole pattern in each and I switched several times over 2 full seasons without any problems (the skis were wrecked before i had any problems with the helicoils). I think this is a good option provided the skis you are using have a metal topsheet. My only real complaints with the system were that it was a little heavy for touring and the screws would work loose if you hadn't switched in a while (I got in the habit of carrying a posi and tightening before each day).
