I don’t see any answers to your concerns, so will offer my .02¢…xcdnewb0313 wrote: ↑Mon Nov 27, 2023 7:37 pm…
Should I have used epoxy instead? If so can I remove the screws and use the same holes with epoxy instead of wood glue? Or should I drill new holes? If I have to drill new holes to use epoxy should I mount the binding forward or backwards of the current holes and by how much?
1. Definitely don’t remount in new holes!
2. Like someone else said, you want a waterproof glue, not something like Elmer’s white glue.
3. If you used a glue that isn’t waterproof, I would remove the screws and remount in the SAME holes using a waterproof glue, Polyurethane being the recommended option.
4. I like epoxy because I think it’s a superior glue and because it adds strength to the core material around the screw, but most bindings are not mounted with epoxy and never have a problem.
5. In modern skis (not wood skis, but skis made with composite construction), most of the holding power for the mounting screw is provided by the top few millimeters (any combination of fiberglass, carbon, or metal). However, a wood core will provide additional holding power that a longer screw can take advantage of.
5a. You want to put the binding on top of the ski, with the mounting screws next to the sidewall of the ski, to visually confirm that the screw is not so long that it will come close to the base of the ski, where it could cause a bulge in the Ptex, or worse, go completely through the base.
5b. When you are putting glue in the screw hole, you want to make sure that the entire inside of the hole is coated with glue (use toothpick or such to work it around). You don’t want the hole FULL of glue, because, like @manney said, once the screw starts turning into the hole, the glue has no place to go except INSIDE the ski, and if there is no space inside the ski, well, you can’t compress a liquid, so it will start pushing and that could damage the inside of the ski, and even make a bulge in the Ptex base. This is one of the reasons the screw hole should be a little deeper than the length of the screw (to provide a space for any extra glue in the hole).
