Alpine Snowboard Plate Systems

[ursle]

Super plate sold on ebay!
He is selling it as an alpine snowboard!!!!!
Hahahahaha!!!!!!!

I stopped water skiing years ago because I hated what 2 cycle motors left behind, but I gotta tell 'ya that thing would be a blast in the water.
Take the straps off and noboard it.
BTW did Kildy make it?
What's it's nick name... Clavicle Slayer?

I just found this picture on the net. The price is considerably higher than the Vist plate (Vist is around 300 Euro (420 dollars) in Europe, the Kessler plate is around 450 Euro (630 dollars)).

By the way, many pros are still using the Vist system (or a similar one) - it can´t be that "oldschool" ...

Ok, I'll bite. Does anyone know how the K-plate is supposed to works? For example, does it float?

Thanks,

Bryan, the photo is from a Russian snowboard shop. Unfortunately, there are no other pictures at the moment.

But it seems that Bola has got more info on the plate .

Intriguing video, with the ski tracking well and clearly independently from the binding plate/springs mechanism floating above. The theory behind the system would seem to be that having the attachment points towards tip and tail of the ski ensures maximum edge in contact with the snow. It would argue for a performance benefit for plate attachment points significantly farther apart than the current UPM pattern. Whether the spring part of the suspension creates its' own performance gain, or, whether one could use a hinge/slide plate as this thread has been discussing but with a long plate and attachment points towards tip and tail to achieve the same effect. A downside would seem to be that as you approach tip & tail the ski/board core becomes thinner and creating attachment points of adequate strength becomes more and more of a problem. SunSurfer

Sunsurfer. I was intrigued by the Anton Glider system also but if you look closely at the photo, you will notice that the bindings are attached to the ski just below the boot as well as at the tip and tail. The Anton system appears to be more of a dampener for the tip and tail as opposed to a decoupling system.

[SunSurfer]

On the Anton website there is a video where the inventor talks with a past freestyle skiing champion. He describes the system as allowing the ski to flex completely independently of the binding chassis above.
The chassis does appear to possibly have two attachment points to the ski.
It looks a little like a plate with a spring tip/tail pressure system created by the springs.

Watching the video shows the beautiful paired grooves created by the riders as the skis carve cleanly throughouut the turns.

Intriguing & thought provoking design with a ski with NO camber (see below). Consistent comment from the reviews I read was how easy it made it to make the skis carve, and how the spring+damper system made the ski tuneable for flex & very damped(a little like M Tinkler's SnowStix)

---------------------------------------------
Technical Ski Data (if known):
- Proprietary flex pattern with zero-camber
- Wood core/triax fiberglass sandwich w/o metal
- CNC machined mounting point inserts
- Stainless Steel mounting hardware
- Aircraft-alloy anodized aluminum chassis
- CNC machined from custom extrusions
- Waterjet-cut, unidirectional composite main leaf springs
- High performance polyurethane elastomer chassis springs and Ultra high molecular weight polyethylene bearing material
- 360 degree-wrap edge, 2+ millimeter,
- Dura Jet carbon racing base (US made, like PTEX 4000 but more
durable and claimed to be faster)
- Rossignol Axium bindings
The skis are designed to have no camber (you read right). The suspension system provides the camber and tension of that camber. Take the skis off the suspension, they would lay flat on the bench. Bolt the suspension system and they are "cambered" for action. Odd, but cool.

ExoticSkis: 08-09 Anton Gliders Carbon EX Skis from ExoticSkis on Vimeo.

Watching the video on Vimeo, the skier now moves on the slope like someone on a carving snowboard!!

This concept may well be the next step on from where our current hinge/slide plates are.
If I was a racer looking to get a step ahead of the opposition I'd be looking at either working with this guy or finding a partner like Apex Composites / M Tinkler to tweak the concept for a racing snowboard.

Interesting design. Binding+Plates design. These are prototype images. Will be available first week of November in Korea. Once it is available, more info. will be revealed.

Sliding mechanism on front / Fixed on rear
Fixed foot angles (54/48) for goofy or regular but customizable by request.
No cants for TDs but works for F2s type cants/lifts.
One can put whole bindings on top of that plates. (The inventor claimed that he designed it that way to reduce weight of the plates system)

Weight: 1.7 kg (3.75 lbs)
Material: Duralumin 7000 for plates and Stainless for axis and brackets
Height from Deck: 25 mm (1 inch)

It's like Christmas without the gaudy wrapping paper! I wouldn't have the patience to set up a camera, I always tear into stuff ASAP.

Nice tease
but I want to see the 4x4 hardware go together

I should make a small correction. Fed-Ex was the carrier.

Trust me Corey, if the camera wasn't right there handy , it wouldn't have happened. Hope to get a chance to put it on a board in the next couple days. Now, which one? Most of my recent Tinklers don't have a 4x4 pattern (note, they are not UPM either). One of the reasons I was thrilled to get the Donek is being able to put it on so many different boards. My hope is that this plate system (or ones similar to it) will take what I have liked so much about the Tinkler plate systems and apply it to my entire quiver. Keep in mind Mike, continues to develope . Good times ahead folks!!

Hey Sean... would you recommend against pushing the slider to the other end of travel, swapping to the other side and mounting the slider block with the tab end facing rearward? (aside from not lining up with the plate's screwholes when using the spacer strips) If recommend against, why?

Elegant. I like the way you've designed in some adaptability.

Do you have any guidance regarding selecting axle spacing and fore/aft centering to start with? So many different interacting factors to consider such as board stiffness, rider weight, riding style, slope condtions, etc.

Looking forward to a demo at SES !!!

I'm not 100% sure I understand the question. If you mean mount the plate with the slider in the rear instead of the front, you're welcome to try it that way. If you simply mean reversing sides the slider are on, you're likely to see a bit of interference between the slider and board when pushed all the way to the end. The original slider prototypes were the same front to back, but it was possible, no matter how unlikely) that the slider would hit the board when the board was bent so far that the slider travel maxed out.

In testing, most freecarvers preferred a longer axle spacing. Some of the racers preferred to narrow it up a bit. If you find that you are easily overloading the shovel, I would do what you can to move the front axle towards the waist. If this means moving the plate, back, that's fine, it may involve narrowing the axle spacing as well.

[bjvircks]

Well, Duh... of course! Now it is obvious to me. You need clearance at the front to keep the board and front bracket from having interference during large board deflections, when slider travel rearward is at its max. Thanks, Sean! Sorry for the dumb question.

Hi Sean,

I wanted to make sure I understood this correctly. You are saying that the plate's stance on the board should be wider in order to soften the board? Intuitively, it sounds like it should be the other way around, since a narrower stance (sans plate) usually allows for more flex with a regular set up. Please confirm, thanks!

[fin]

nekdut,

Cannot speak for Sean but here are my observations on pivot placement:

The placement of the pivots of a plate system do change how the entire system feels dramatically. Some of the conclusions from last year where as you went wider with the pivots the board became more stable and powerful. As you went narrower on the pivots, yes, more of the board was now freed up to flex but if you went too narrow (subjective on what is too narrow) there was a strange uneasiness in the system. Or rather it became a bit unstable.

This instability would be compounded even more if the plate was not rigid enough to stop it from "positive" cambering during the turn. This would happen with a soft plate as your feet where so outside of the picots that during a turn the plate actually decambered opposite from the board. Personally I found this very uncomfortable and strange during the turn. I would then move the pivots outward and stability came back. This just told me that if you want to run narrower pivots points the plate better be very rigid to support that.

Initially I thought the ultimate spot for the pivots would be directly under the center of each foot. It was symmetrical, put all your weight right on top of the pivots, etc. But as always, in practicality and testing this did not turn out that way.

You also have to think about the geometry of the narrower pivots. As you go narrower clearance with the board as it flexed become an issue. So you either limit the amount you can move the pivots inward or raise the height of the plate for more clearance.

Now ask me about my theory on why the sliding pivots works better in the front than the rear

Refer to Fin's response here. It really is something you're going to want to experiment with.

[bjvircks]

Since the "Name the Bomber Plate" is locked... I've just got to toss this idea out somewhere.

the Tecton Plate

like tectonic plates that move relative to one another, changing the world as we know it.

[leeho730]

Now ask me about my theory on why the sliding pivots works better in the front than the rear

I guess that sliding mechanism in the front allows the nose to be more flexible which would be useful for the rider in terms of adjusting the radius of the turn...?
