Binding mounting myths:

[GeezerSteve]

Right, Zeno's pullout tests provide interesting data, but they don't duplicate real world pullouts. I'd bet that a significant proportion of ripouts involve one or more loose screws, which introduce rocking forces. IME, screws (especially Dynafit toes, which are prone to loosening on some mounts -- maybe due to harmonic vibration?????) stay in betta when they are epoxied.

amazing goop or 3m marine epoxy (1 part, urethane based) is the best ski mounting glue. period. it works on all skis regardless of construction in a superior manner, regardless of binding. it bonds as strong or stronger than epoxy, but screws are easily removed.

wood glue is water based. it should be no suprise that water gets into the core/threads. you put it there. simple as that.

Since reading a previous post regarding Urethane I've been thinking the Hardman Flexible Urethanes were good options for binding screws. Any experience or insights Marshal or anyone?

^^^ 100% Agreed! ^^^. But this thread is proof that you will never convince some people to not overkill every binding mount by incorporating some kind of gnarly permanent 2-part epoxy.

Look right next to the Urethane in that link picture. You will see... binding glue!
It's all you need, unless you messed up somehow.

Wow. I did not notice that when I ordered it, stocked, filled the 2.2 oz bottles, made the labels, took the picture, typed the text and posted it in our store.

Like all things skiing, waxing, tuning and binding mounting, etc, people like choices, have differing perspectives and opinions, and love to debate.

[DropCliffsNotBombs]

I must worn you... I'm a master debater!

[AlpiNord]

There's no debating that.

Is this the stuff? The only I found here in Germany. The description only says shoe repair, so I'm not sure thats the right one.

Any polyurethane based D4 rated wood glue is just fine. Don't overthink it. Pick Soudal from the local hardware shop or order Gorilla Glue because it comes in a nicer bottle

rasi, no hardware store in my area stocks PU-glues. I recently ripped out two bindings within two days so I'm being a bit skeptical. I mounted them with d3 wood glue from the hardware store. I don't know if a different glue might have changed anything, but I want to get the strongest mount possible to prevent this situation from occurring again.

marshal, I actually found that one on the german ebay and ordered it. Thanks.

[marshalolson]

2 pullout in 2 days points towards something being wrong well beyond what glue you are using.

just saying.

[cyclerower]

jep, probably. One was a shop mount, so I don't know if they might have fucked up something. However that was about the 30th day on them and they held up to that point. I did the second mount on my own. Used a ski drill bit. No spinners and the binding was sitting plane one the ski. So I can't think of what went wrong. Maybe just bad luck and the leverage with a 136mm ski on hardpack.

[Jethro]

We have been hearing about the forces wide skis exert on the bindings here on TGR in several threads. I am curious as to how skis are mounted at the world cup race level. Granted, the skis are narrow, but the racers are big guys on riser plates, and I'd say they ski somewhat aggressively. How are the binding screws and plate screws treated when mounting?

[cinnepa]

going to be reusing some holes....give some epoxy names so i could hit home depot tomorrow. actually going to add a small lifter plate with the longer screws that came with the px14 setup. originally had mounted without lifter plate and shorter screws.

actually no rush......think i'll pickup that marine-goop marsh recommended

[Zeno]

Any slow set two part marine epoxy. Home Depot usually has something in this category. I like G-Flex by West Systems which you can get at West Marine.

One part adhesive sealants like 3M 5200 (which you can also get at Home Depot) should not be confused with two part marine epoxy. The sealants are more flexible but not nearly as strong. Epoxy is more often used in structural applications compared to sealants. In my experience, mounting skis with 3M 5200 is messy, but works well to keep water out.

I'm about to mount an old pair of Pow +s, but this thread has me second guessing a couple of things so I thought I'd ask the group opinion on how I should proceed. For any who might not know, the skis have one (maybe two?) layers of metal in them, and are wood core.

Available to me I have the following:

3.6 X 9mm Bit
4.1 X 9mm Bit
#12 AB Tap
Helicoils (these ones...)
Wood Glue
JB Weld
Some other random two part putty style epoxy

My prior knowledge and experience would say just use the 4.1 bit, tap, and wood glue and I'll be good to go. While I'm sure this is still the case, is there a better way? With all the charts and figures and whatnot that's in here I got kind of lost. Should I be using the 3.6 bit? Tapping? Not tapping? Wood glue or one of the random epoxies in my garage? Next time I'm in the market I'll probably try what Marshal linked to above, but for now it's just what's here...

WWMD??

[Jethro]

4.1 bit, tap it, slow cure epoxy if you want to use epoxy. I would stay away from JBW and putty epoxy. Non-water soluble wood glue works fine for sealing the wood, but epoxy is better all the way around. Better seal, better retention, just better.

WWMD??

Just mounted a set again last month, 4.1mm, tap, marine goop, done. I do have to mount a set of Spats if you have any further insight from your mount last fall.

Assuming you have already seen my Volant Mounting thread,
my advice is drill slowly, use lost of lube, and definitely try the screw punch if you don't have access to a cobalt bit and a press... just make sure you use the vice grips so you don't go too deep!

Alpine screws or inserts? The glue/epoxy is mainly for sealing when installing alpine screws, not to rely on for holding strength. Wood glue or silicone sealant are other options. Epoxy = overkill/no-no for some, desirable for others and no consensus as far as I can tell.

Gorilla Glue expands and not desirable, IMO. The Orange High Peel Strength Hardman works well for sealant, inserts and general repairs so does the blue general purpose. Not sure about the Loctite Marine.

[El Chupacabra]

That Home Depot Loctite 2-part Marine epoxy is what I've used quite a bit. Works fine, IMHO. Dries to a grey color, in case you are using it for any topsheet repairs and care what it looks like.

[Bird Blaster]

I would be using the stuff for alpine mounts. And I have some plugs to seal in too
