Binding retention. What do you use?

[skibum]

I have searched around the site but am having trouble seeing what people find to be the best material to use for binding retention. Do you just leave it without any extra layer or use a layer of uni or matt glass or just another section of triax? I have seen people using bug mesh but was kinda wondering what others are using. PMgear I guess uses/used "Dore – Tech" but I don't really know what that is.
Sorry for the basic question here but just want to limit the things that can go wrong.
Thanks for any input

I'd got with some kind of hardwood stringer and an extra layer of fiberglass that you push the inserts through.

What kind of skiing do you do? I'm a typical east coast skier. I haven't used anything extra in my builds so far for binding retention. I don't hit the rails or terrain parks, just your normal fast skiing, bumps, glades. No problems so far. It may depend on what your core thickness will be. Mine have been at least 10mm at center.

Riding is on the west coast so powder/variable snow. But I want them to be pretty bomb proof as I'll be doing drops and lots of tomahawking.
Will Prob be using a solid maple core. Center thickness 10-12mm.
thanks for the tips

Definitely a hard wood where the screws will be anchored.
Then as you said add a layer of glass in the binding mount area. Some use triax. I think that chopped mat is the best to use because it will make a strong matrix to anchor through.
Kingswood use a really thin piece of aluminium.
Some use fly wire mesh, but it has been a bit contentious whether it works very well.
When you mount put a bit of epoxy on the screws.
If you are really worried then I suggest you get your process dialed then start using inserts in your core. These are much stronger.

I think I read somewhere the "dore-tech" is just regular window/door screen mesh, Pat just wanted to give it a technical name (door-tech -> dore-tech) to make fun about all this technical language bullshit ski industry is providing...

On my first pair I used a wire-screen mesh underneath the top layer of glass. On the second I used an additional layer of biax. Nothing on the third pair, and binding insersts for my board. I had zero probems with each method.

door tec is patented. He used several pieces, like 2-3, overlapping in the binding area of aluminum window screen.
Chopped matt glass is kinda industry standard.
Pine type woods will provide the least amount of screw retention.
Maple will do pretty well. We put stringers of maple in that area for a solid screw hold in our poplar boards.

I've used aluminum window screen.
I think its best to use 2 or more layers.
1 layer didn't do much if anything.

I've used aluminum sheet, that worked stellar but added a bit of weight.
A layer of VDS on either side for good measure.

These last few I've been using an extra layer of triax, seems to work alright.

I always use epoxy in my screw holes now though. Just use a little syringe to put a bit in the hole before I sink the screw.

YMMV

Pat hasn't patented anything, afaik.

Thanks very much for all the advice. I like the Dore-tech name. It had me going for sure.

He told me otherwise, to my face, when I visited the shop a few years ago.

Damn you man! make me look up "as far as I know". I just can't get a hold on texty interweb acronym speak stuff.
Almost going FOG.

I know huh. I bet he was dded with you. Patents are expensive, and I don't think pm gear is rolling like that. I did a cursory patent search and found nothing.

FOG is fun, make the same new friends every day.

I had very little sleep the night before but he was pretty fuggin' adamant about it. He said it 3 or 4 times to me as we looked at the core stock.
