Cruse Control

[Garry H]

Just Knocked this up in the workshop
My take on a cruse control
I wanted somthing that did not rely on friction to stop it moving
so have built a ratchet into it
Tested it out and it works a treat
Will be making one for the 1100 next

looks good

You making any more ,and if so any you are you selling any \/

WOW, I like this, keep us informed if yur going to produce any more, I presume it works well, or have you had time yet to put it through it's paces ?, What materials have you used ?, looks like stainless, would the pawls/Pins work better in something like F/Bronze ?.

That is a very nice effort.

But, after having a wunderlich on my last bike, I think I'll knock up something different for my next bike.

I only need to 'lock' my throttle for a few seconds to shake blood into my hand, or reach a zipper, or something and the fussing around screwing on the friction lock is more of a pain that I'd like...

So, I'm thinking of a bicycle cable running to a wedge lock arrangement in place of the twist friction, pull on a lever with the Left hand (finger/thumb), this puts friction on the throttle... let go of lever and throttle is loose again...

I'll be sure to post photos of it when I get it done... (or maybe someone here will run with the idea and I'll buy one... )

Poor blood flow into arms - have you been checked out for thoracic outlet syndrome? (I get similar issues on the left helped by a chiropractor but I guess surgery needed eventually).

These are nice but should be at these prices.

I find on long runs ( motorway mainly ) it will be useful
You can put a preset friction on the throttle so it reduces the grip you need
Most of the time i won't use it but on a holiday trip i will
When not in use you will not even notice it's there
and with a positive ratchet system it won't move when set on or off or anywhere inbetween

Looks well made but also that it has a limited number of possible locations which I think you'll find are not always going to give you the throttle position required.
I have a Jaws throttle lock and it works pretty well but it is surprising how finely you need to position the throttle to keep a constant speed (of your choosing - obviously there will be a set speed for any throttle opening , given all other factors (incline, bends, wind) remain constant)
Bit of quality metal bashing there though

edit just studied pictures again and it looks like the pins hold the friction ring in certain positions as opposed to holding the throttle in a set number of positions - am I understanding it correctly?
So it allows for different levels of friction? - that would make sense and obviate my comments above.

cruise control

was wondering if you have or are able to produce a drawing for this, I may be able to get one made, but would need a drawing

 

[Garry H]

The ratchet allows the stop to come out in .05mm increments
Thats plenty fine enough for precise adjustment...But not so fine you are forever messing with it
It's no problem to adjust it so the throttle springs back normally, slowly, fairly quickly or not at all
I don't plan on using it on bendy roads just long straight ones
No drawing i just designed it as i went along. The pics should tell you enough

From a safety perspective .... is there a reason you've not included a non-rotating spacer as in the Jaws setup? The throttle closes in the same direction as you tighten the lock therefore if you reach a situation where the friction between the grip and the cruise control is more than the grip of the internal ratchet arrangement, attempting to close the throttle will lock it up even tighter!
I think a useful mod would be to either add a non-rotating spacer, or use left handed threads on the control thereby causing it to release on closing the throttle?

cruise control

If you decide to knock some up i for one will be interested. Used a throttle stop plastic thingy on a European trip this year and worked a treat. Only problem is that it did not last too long before it snapped in half

Have put some thought into it
Left or right hand thread could tighten up when you shut off or open it up
You don't cruse at full throttle only small openings so I recon a right hand thread is better than left
Plus I have put full throttle on then rotated the lock to create what you are discribing there is still nowhere enough friction created to stop you moving the throttle with your hand
The ratchet requires far more force to move it than the throttle drag generates with 1 detent spring and plunger..... I have fitted 2 just to make sure its reliable and stays that way
