Thread: Remounting close to old holes

I posted this under the Paper Template thread yesterday and didn't get a response, so I'm trying a new thread.

I need to remount my dynafit toes just 7mm from the previous mount. I switched boots and use the Vertical Race Ti binding that does not have an adjustable heel. Because of a very bad combination of the difference in the bsl of my previous boots and my new boots, the best option is to move the toe 7mm back. I know 7mm is not much of a difference, so should I use nylon inserts, helicoil, or just remount them? I don't want to do the remount unless it will be solid since I use this setup for ski mountaineering. The ski are Karhu Sprire BC. They don't have a metal topsheet. BTW, if the 7mm difference is not advisable, the best option for a remount that's 10mm from each of the old holes is to mount at about 2 cm behind boot center, which is a bit farther back than I'd like. Thanks for any advise.

7mm's is safe to remount. Don't go to helicoils since that will remove even more core material from the toe area.

Or be safe and just use plates. I'm not a fan of redrilling that close for a Dynafit toe piece given the torsional stresses you put on the toe piece when skinning.

And please learn to use the search function.

Search, indeed, but here's a really specific reply for you:

I just pulled a Dynafit toepiece out of a Surface Live Life (no metal, wood core, fiberglass topsheet) because I mounted it too close to old holes (and because I like to jump off of things). The holes were closer than 7mm--perhaps 5mm.

I'd say at 7mm you'll be fine, especially on a narrower ski with (presumably, since you're using race bindings) smaller boots and less hucking.

In my case the weakness was not the core, but the fact that the topsheet cracked in between the old and new holes. I repaired the ski(s) by filling all holes with a mixture of chopped-up fiberglass cloth and good epoxy, then covering the whole toe area with a new sheet of fiberglass cloth and epoxy, then redrilling and mounting. I even put inserts under the 3 holes that had pulled (i caught it before it completely fell off), and so far, so good (about 10 days since, all types of conditions). Definitely not ideal, but better than dumpstering the skis.

In general, I find it's better to just relax a bit and try it--the worst that can happen is you'll destroy a pair of not-very-expensive-to-replace skis. (Damn, those race bindings are probably worth 4x the skis, anyway.)

Thanks for the replies. I'll try remounting at 7mm and see how it goes.

Make sure that you fill the old holes completely. Lots of people use golf-tees and epoxy. Myself I use a good quality epoxy, but you have to make sure there isn't an air bubble stuck down in the hole. A heatgun or hairdryer is good to help make the epoxy flow better if its too thick to get it filled.
