What plastic to make binding shim (bootfitting related)

[Patches]

What's a good plastic to use for make binding shims? Mine will need to be resistant to loctite since I have inserts in my skis. I think nylon?

Also I am open to other ideas... here's the situation [PULLS UP SHIRT TO SHOW ABS]:

I use Tecnica Agent 130s + Dukes for a resort boot and Dalbello Viruses + Dynafits for BC. The Viruses seem to have much less forward lean and I'm having to work really hard to get into my normal stance. So I was thinking about putting a shim under the back half of my dynafits to increase ramp angle.

I skied the Viruses + Dukes inbounds yesterday and the combo was really really making me fight to get forward. I had less of an issue with the Viruses + Dynafits but it was still noticeable.

The Dynafits put the heel 0.17" higher than the Dukes. So I was thinking about an additional 1/4" shim for starters.

Any thoughts?

If the Tecnica Agent is like the older Diablo boots, they have a tremendous amount of forward lean. If that works for you, great, but it will be difficult to copy that stance in another boot.

Do the Dalbello Virus boots come with the little plastic shims you can insert to increase forward lean, like on the Krypton? (and IIRC, very similar to the old Raichle Flexon; I don't know if Full Tilt kept the same design)

I went to an industrail plastics company who sell large sheets of plastics ,nylon ect to the mills

they gave me some small scraps for 5$ which buddy put in the coffee fund

I've had nothing but good luck with Lexan/polycarbonate.





They're often available at hobby shops and definitely available at plastic supply places. They're easy to work with with typical woodworking tools (but probably want a very fine saw blade), their dust isn't especially toxic, and they have not developed any cracks over time. (This is version 2.0, I sold my first set with the skis.)

I use high density polyethylene (HDPE), the stuff used to make readily available white cutting boards to which Conundrum refers. I get my HDPE plate stock from TAP Plastics. If you need to machine the stock down to a custom thickness, HDPE machines easily and clean with a HSS end mill or other common tooling.

Thanks for the tips, I think I'll get some HDPE from mcmaster-carr (no plastics shops here). Nice looking shims DtEW.

Its funny after my years of carping about floppy-ass AT boots that I wish these were a little softer so I could get up on em...

El Chup I ski way far forward, I really like to lean on the tongues of my boots. Possibly too much, I will spend a couple more days on the virus+duke combo to see if I can learn something.

my alpines had too much lean for me and I put shims under the toe pieces ,I do not remembr which type ,its wasnt white HDPE and it wasnt clear lexan ,it was black

it cure my problem tho

I've used polycarbonate and delrin.
I got the polycarbonate/lexan at home depot. Stay away from the acrylic/plexi-glass.
I got the delrin at mcmaster. Delrin is nice because it can hold tapped threads.

I had problems with my bindings rotating when spacing my dynafit toes. It was a bummer because it would rotate enough to rotate my heel piece into ski mode. But you're spacing the heels, so I guess it's fine.

If you are using comforts or verticals, I think the classic style toe spacer is thinner, which would maybe accomplish the same thing. Not 1/4" though. I guess you would lose out on the stronger crampon mount too.

Patches - shoot me an address and I'll ship you some scraps...

I have copoly (polypro + polyeth - white plastic) or straight polypro (translucent white) in 1/8", 5/32", 1/4" or "durrplex" clear lexan in 5/32". Have some 1/4" modified PE too - maybe a little soft though I'd think.
