    Epoxy vs inserts vs...

    Last year I broke a carbon fiber looking plate on my Tours, and the shop got Marker to hook me up with a new pair, despite being out of warranty, which was great. Older narrow patter, switched to the wider pattern, asked to go 1 cm back. On one of the skis, didn't quite make it 1 cm back.






    Not real comfortable with this spacing. That figure 8 in the middle kind of sucks. I liked the original mount, and at this point, would have to go 1 cm forward, or 2 cm back. I have a better home for the tours, so I picked up some older Barons to re-use the original holes. Not too keen on moving the binding forward or putting a third set of holes in the skis, but that is an obvious option as well.

    If I can put the narrow mount Barons safely in the original holes, I am back where I started, which was a happy place.





    I figure filling the EPF holes with epoxy, JB weld or what have you on this ski (cham 97 w/metal) should be OK, except that middle hole.

    If I understand the older Baron correctly, this middle screw should be snug, not tight. (I wonder if that's why the old Tours broke..)

    My thoughts are to to use epoxy to fill half the figure 8, coat the screw with epoxy, snug it down, then back off slightly. It will thread in on the old threads, and in the figure 8 area the epoxy will create new threads.

    I can also do an insert, but that widens the whole figure 8 thing. Also not sure the best way to go snug-not-tight with a machine screw and have it stay that way.

    Or just say fuck it, and go a cm forward with the binding.

    I'm not sure that center hole has much pressure when you're skiing and since the cham 97 has 2 layers of metal, pulling out a screw seems unlikely unless you over torque the screws when mounting. I'd just glop some epoxy in there and not worry about it. If you pull a binding, just pick up another pair of Chams for cheap (They seem to go for sub $200 online).

    I would use the EPF holes (already drilled now, why mess with it more?). Go with a threaded insert or pound-in plastics and standard screws (super strong).

    The middle screw doesn't take much force. So in all likelihood will be fine--especially with an insert of either type. I would ski the above.

    I've put a good number of days on these with no ill effects: http://www.tetongravity.com/forums/s...(photos-within)

    The middle screw just holds the lever in place, doesn't do shit when actually skiing.

    Fill those bitches up with epoxy and go shred. If you tear one out helicoil it and move on.

    Agreed. This is one of the only cases where using epoxy on your binding screws would actually be a good idea.
    If the hole's threads are still good and you epoxy the screws in, you won't be pulling out any screws from that binding, on that ski. Trust me.

    about the tension on the middle screw-
    Am I right to snug it, then back it off slightly?

    I back mine off a quarter turn with Dukes on plates.

    The middle screw spun like a merry go round.

    It's sitting in a big pile of JB marine.

    We'll see.
