Custom/Hybrid concept pole brake

[Hfurll]

Rode as couple skis last year that had the pole so tight no spring was needed, BUT was told once you get use to it there is another level of control...
I can see both sides of that reasoning.

I didn't think much of it until I had this dream of doing a heal clicker the other night.
Its Amazing how kick A$$ I ride when dreaming!!!!!!! Nothing like the real world!

Remembering when BMX freestyle was NEW and prototype bolt-ons that would let your bars rotate 360* seemed not possible and awesome at the same time, now the norm...


If you could lock the bars/ Pole, wouldn't another level of progression or tricks be possible????


My thoughts were to be able to stop the pole with a pull of a lever, same concept as a trim lever. Hard mounted brake caliper to the pole and a rotor mounted to the bracket with the same curve as the pole pivot.


This would let you feather the lever like a Moto front break for some things and Lock it solid for a new level of aerials..


What do ya think? Used brakes setups with a wide range of quality have hit the market cheap...


I'm out my league here, so any input would be great....

 

[chad]

interesting!

I like the sound of it

 

[haggis]

Sounds good, space down at the pole bracket would be a big factor but im sure it could work!

I thought that a fixed steer sj with some kind of gyro style 360 degree steering system would be cool, could open up a whole new bmx style tricks?

Fixed steering setups have been around for a while now, I haven't seen a whole new level of tricks open up because of it though.

I know the fixed steer has been around i was referring to some kind of 360degree steering system.

so you want to put a gyro on a jet ski?

 

[grezzmky]

so you want to put a gyro on a jet ski?

no, a lever that locks the pole in position.

Explain how that is going to work exactly, it is slightly more complex than Bicycle steering and my other comment was directed to hfurll

 

[the WaTeRhAwK]

I think a small set of soft spring coil-over shocks mounted at an angle at the bracket would do the trick.

I only said that i thought it could be cool, i never said that i had thought of the complete mechanical workings of it! Yes there will be issues with regards to the throttle cable/ start stop switch and yes there would have to be some kind of stop system that can allow normal steering but allow it to rotate 360 degrees when needed. But i havnt thought anymore than that and have no plans to either. I think it was thomas pages (fmx) That had a setup that allowed him to rotate the bars only full 360 degrees, thats what kinda got me thinking.

my friend and i thought of the same idea using a downhill bikes brake system since the are small... your way of mounting it was the same as ours

The brake set up is a pretty interesting idea. Would be nice if you could just lock it there and not have to hold it.

I've got no desire to do a heel clicker because if my feet are that close to my ears...there is some serious going down that I don't want to be a part of.

But in all seriousness, if you want to start trying tricks like that, they are pretty easy with a short limiter rope, or one with an extra carabiner that you can clip in when you want to shorten the travel of the pole. You can see the rope pretty clear in this picture. The only real problem with this set up is that it takes a few seconds of dicking around to get the rope to clip in. And that is not really such a big deal, except when you are competing it can really throw off your momentum.

The throttle and brake cable are easy , just make the center tube hollow and run the throttle cable and start stop switch wires through it, the steering would have to have some kind of stop system that could be disengaged to allow full rotation, that would lead to some exciting moments not knowing exactly where the steering was or if it was disengaged or not.

A few of us here have toyed with this idea also. I've been especially interested because I don't care for the tight pole setup. A lot of manuvers are be pretty hard to pull off with out it though. Mark Gomez said that AC was working on some type of proto type of this already. I like Ross's idea of having the pole be able to lock and then release with out actually having to be pulling the lever constantly. Lets use this thread as a think tank to iron out any potential problems.

Maybe a solenoid activated plunger? You'd fix the solenoid on the pole bracket and have it lock into a hole on the pole. You could even have multiple holes for multiple lock angles. You would activate it by a single button on the bars: one button push for lock, one for unlock. The plunger is held in against a spring to let the pole move, and then let go once released by a button push. It clicks into a hole when the pole is moved to the right angle. Then the solenoid pulls the plunger back to release the pole.

On the one hand I like that idea because it would certainly work and be super-easy to use, but on the other it means relying on electrical components so I'm not sure how reliable it would be. There are a bunch of other electrics on a ski of course, so maybe that's not an issue.

So basically you are talking about a beefy billet hollow universal joint?

 

[Boris]

How about just mounting a car seatbelt up on the pole and running it down to the tray like a limiting rope.
You can remove the locking mechanism and just use a metal pin that you would push in just under the chin pad to lock it to what ever height you needed.

It wouldn't stop the pole from going down though.

Then the solenoid pulls the plunger back to release the pole.

I was thinking something along this line also, similar to one of those aftermarket carb cable wheels, the ones with a bunch of different holes in them but with out a electric solenoid just a cable/lever control. On a closer thought though a disk brake set up seems like a better idea to me because with this type set up the pole will still be able to “give” or slip if you come down to hard on it. With a solenoid set up, when the pole is in a locked position then I’m thinking the leverage of the pole would just sheer the pin on the solenoid if you came down on it to hard like a 4 foot cheater bar on a 3/8” bolt.

On the solenoid engagement topic. How about two plates with small round teeth. The teeth would be ridges and grooves though. And one plate would have tension springs behind it.

So when the rider pushes the button the solenoid would push the plates together (or one into the other) and the grooves would line up easier than pins and holes (in theory lol) Even if the rider had to move the pole up, or down a tad, the grooves would line up and it would lock in. The springs (or tension) behind the other plate would work kind of like a break away when things go bad and the pole has to move. It would be difficult to move the pole, but it would still move.

Thoughts? Like amp draw for a solenoid while it's engaged. And is that even possible?

I'd like to see where this goes.

if you came down on it to hard like a 4 foot cheater bar on a 3/8” bolt.

I was thinking about that - definitely a flaw. But like Ross said, it would be great to lock the pole and not have to keep hold of a lever to do so. So, perhaps a solenoid activated disc brake is the key. Again, one button press for lock and one for unlock, but this time the solenoid is actuating a disc brake rather than locking a plunger in a hole. That way it stays locked, but there is still some "give" if things go awry. The other advantage of doing it this way is that you could lock it in any position, not the preset hole positions.

Another thought: maybe there are three button pushes, and they cycle like this: off-stiff-locked-off etc. I like the idea of having a couple of different "lock" settings with differing amounts of brake activation.
