How much epoxy when mounting bindings?

[sb]

It must be Monday.

"a dab will do ya"

same thing your mom says about astroglide and buttsex

One big drop; as much as a bamboo teriyaki skewer (which is a great way to get it in the holes) will hold.

[stuckathuntermtn]

Wow. Is there anything in the PNW that humidity doesn't pervade into?

Ha. Me and Rog agreeing on something. Wait...shit...that must mean I'm wrong.

Less is more with the slow cure stuff. It expands a fair bit. Enough to put dimples in your bases if you're putting inserts in thin skis like me.

FTR, the pics of the rusted screws was pulled from Zeno's post on page 3 of this thread. Zeno published very informative results of pullout tests on ttips (RIP). Some of the results appear in Zeno's table on page 3 of the thread linked above. The evidence favors epoxy over Titebond II or other wood glue.

This is the same method I use. After I dab in the epoxy, I like to come back a minute later and pop the big air bubble in the center of the hole. Key step to a bomber install

Using the proper bit, the proper mounting glue, and proper hand tightening is the key to a bomber install.

Those are all important things, but if you don't pop the bubble, your bindings will fall off.

Not if they're glued to the ski!

You might be onto something. Someone should use some of this uber strong evil epoxy stuff to mount some bindings, without screws. There would be no problems with remounts and overlapping holes.

[splat]

I screwed through the base of some skis into the soles of my boots and skied that way at Mt. Hood one summer. No one even noticed I had no bindings.

[AlpiNord]

Did you tap the holes in your boots?

To do away with bindings altogether, take Splats approach but use shear through bolts and nuts. Use the correct shear bolt to match your DIN setting. Bring extras for when they 'release'.

[sb]

You mean like shear bolts for a snow blower for when you chew up the neighbors Sunday paper?

I would think it would be critical to tap the boots first.

[AlpiNord]

Yep. Those ones. Huckers would need higher DIN shear bolts than those who don't.

[icelanticskier]

I like the direction this TR is taking.

carry on

I don't tele so the pullout force on the screws is about half since alpine bindings use about 8 screws and tele uses 4. (Unfair unscientific generalization)

[DropCliffsNotBombs]

You mean to tell me that those toothy screw threads are useless to secure my bindings to my skis without also slathering permanent epoxy all over the place? Wow.
If you don't put a puddle of epoxy under the bindings, you'll risk ripping them right out! Right?
Impact hammers, soldering irons, chisels, and stripped screw heads are just part of all proper mounts?
No. No they aren't.

Nobody said that. Nice try, strawman.

This is the monthly ski mounting fetishist meeting. Overkill isn't enough here.

So do you 'slather' binding glue all over the place on your mounts?
Or go with the 'puddle' method?
C'mon man!

If I was mounting multiple pairs a day in a shop setting, I would most definitely use binding glue, unless somebody specified epoxy.
I use epoxy on my mounts and have done so after having a binding come loose on a multi day trip years ago. Had to ski out with a duct taped on binding(luckily one screw still held or I would have been postholing out of there). Now, I could give a fuck less if someone has a hard time removing screws in a shop setting.

The main purpose of glue is to lubricate the screw as is goes into ski and to keep water out of the ski once it is screwed down. Binding glue will achieve this just fine. Wood glue or even Gorilla glue is not a good choice.

Also, for the home mounter, it makes more sense to buy epoxy that you can use for other projects, than binding glue that you more than likely will only use to mount bindings maybe once a year.

A good point to differentiate. It's binding screw sealant, not 'glue'.

From SVST after a PNW doubter asked about durability:

"That binding sealant is water based and designed for wet applications. I haven’t had a single shop tech complain about it not being waterproof enough. It probably all depends on how much is being used. There’s a bit of a balance with anything like that. If you use too much it can expand and damage the ski and if you don’t use enough then it’s not going to seal correctly. I would say if the guy knows what he’s doing it will seal correctly."

i've mounted well over 100 AT and tele mounts this winter all on one lil bottle of montana mounting glue. not one single time have i used epoxy or have i mounted a ski that required it. no pullouts, no issues. in the last 10 out of 20 years mounting skis i've prolly used epoxy less than 20 times. atomic rt -80/86 and the old atomic built bd's always got the epoxy drip.

carry on with all the beaten dead horse overthinking analytical(sp?) bs
