I have a question that I am sure has been asked but I can’t find the answer to.
How many times can I remove a binding and reinstall in the same holes before the mount becomes compromised?
I have a ski that I removed and reinstalled the heal once (pivot). Now I want to swap the heal again but with a different brake width. Is two times too many?

G10 dowel + gflex for those close holes next to new inserts.

I haven’t taken it off yet but when I remounted the heal the first time the screws went in tight with no issues. Yes, I can use the same screws or new ones if that was better.
There is no metal in this ski…
It sounds like epoxy with some sort of a binder is the way to go.
Question on the helicoil, I put one in once on a ski and had some issues. I put the helicoil in and then test mounted the binding to make sure all the holes lined up. Whe I backed out the binding screw the helicoil came off with the screw. It was only one screw so I put it back in with some wood glue and mounted the binding.
I am I missing something? Should the helicoil be able to come out that easy?

I’ll pile on to the previous advice, G Flex and solid wood hasn’t failed me yet on many swiss cheesed skis. Or epoxy inserts in, better long term than helicoils.

I've never used a helicoil insert before just read about them in the past. Similarly to a BF/QK insert its increasing the surface area for your male/femal thread interface and in theory increasing your pullout strength.
Personally - if the ski doesnt have metal, you're doing all four screws on the pivot multiple times, and your not totally sure about how mangled the threads are - I'd go with a full threaded interface. Definitely more piece of mind than winging it and having you rip out of your bindings at a very inopportune time."Poop is funny" - Frank Reynolds

As long as you’re not getting spinners you can do it indefinitely. If they all torque down fine you’re golden. If any spin, that’s too many. Could happen on the second time, could happen on the 100th time. "
This^^ it works until it doesnt so you can do it until you get a spinner then you will be heli-coiling or moving the binding 1/2" or rebuilding the hole with epoxy & a filler ( FG, steelwool, wood )
you can't treat the threads in a wooden ski like the machined threads in a piece of metal forever, what you can do is on re-instal is gently turn the screws backwards in the hole and you will feel the beginning of the thread so you aren't cutting new threads every time and use epoxy
My take on wooden dowels is they work unless they don't work, lots of people do it but its not best practises, moving 1/2 " into fresh ski top is best practises and nobody can feel it, thats what I normaly doLast edited by XXX-er; 01-08-2022 at 12:46 PM.

I have never done a helicoil, I am certainly not against them, l can see why a shop does helicoil and all the things they do in a shop, I would too if i was pumping jobs out of a fully equip ed shop to make money for the owner.
But for the one off spinner fix at home on a dark and stormy night, as as opposed to ordering a helicoil kit which would be a couple weeks or go to a shop with a 2 week backlog I did the epoxy FG cuz it was instant and I had the materials, it worked/ has always worked so I just kept doing the epoxy/ FG fix,
others have also done the fix with success, there were some skeptics for sure, so they can go order a helicoil kit or take it to a shopLast edited by XXX-er; 01-08-2022 at 04:46 PM.

After reading all the responses (thanks for the feed back) I think my plan is as follows
Remove the heals, use a two part epoxy, gently try and find the starting point of the existing threads by rotating the screw backwards, then slowly tighten until tight.
Hopefully I don’t get a spinner, I looked at the helicoil kits and they are like $150.00 and come with 100 helicoils, which is over kill for me.
Is there an “official” binding torq spec? On first mounts I usually tighten to the point that it feels good, however I don’t want to risk over/under tightening in this case.
On a side note. The reason I am going through all this is that I have a new ski that is 102mm under foot and I have a spare set of pivots that I plan to put on them but the brake is 115mm. So I am going to take the heals from another pair of skis that have 95mm on them and eventually replace them. Everything I read and looking the the 115s sitting on the ski tells me that they are too big. Am I wrong? Could I use the 115s and bend them in?

bother with what
obviously you haz
and why you have 3x the posts of anyone else in the thread"When the child was a child it waited patiently for the first snow and it still does"- Van "The Man" Morrison

yes, in some cases the torque spec is printed on the topsheet. But do you use a torque limiting device of any precision to drive the screw? Can you feel the torque you’re applying with your tool and quantify it?
I usually tighten them until the binding is flush with the ski. such that I can’t see any light pass between them when I hold the ski up to a source of light.

Picked up a pair of used Billy Goats on here and I'm trying to figure out WTF the holes in them are for. One set is for a STH at ~332 mm BSL but I'm lost on everything else.
The other six toe holes are spaced at 36 mm width-wise, and 46 and 22 mm along the ski length. And then there's one at the center of the ski, on the line. Four of those six toe holes, plus the center one are close to being an OG Duke mount but the spacing is a little bit off both between the main holes, and from them to the one at ski center. And then the heel holes don't match a Duke setup at all.
There are 8 heel holes once the STH ones are taken out. The front two are spaced 36 mm apart, and the other six are in pairs at 42 mm spacing. The first set is 21 mm behind then 36 mm spaced ones, and then the remaining pairs are 80 and 25 mm back.
What the hell am I looking at?

Hole at ski center could be a duke mount
