Hi there,
I am in the doubt of my clipper's 3 gimbal ...
he's normal that the gimbal has this this movement?
he's a normal tolerance?

Please help.
I have attached file.

thanks in advance

Marco

Yes, that is normal. Under load, the tolerance will disappear.

Thanks Alan,
I've seen that under load the tolerance disappear, but I was worried
for the normal position.

Thanks for help!

Is that REALLY normal?

My V2 gimbal has no play in it at all, so why should the Clippers gimbal?

Richard and Marco-

That play is normal and there is no advantage to removing it. All the play is removed when operating, In high mode in moves together, in low mode it moves apart, and in both cases it stays there.

It can be shimmed to remove some of the play if you want, but some play is good for the operation of gimbal - less friction.

It's a nuance of the design..

Not to necessarily disagree with your point, but I don't understand why having a sloppy gimbal handle would be advantageous in resulting in less friction, as the bearings should be doing all the work, no? Especially if it all tightens up under load, then that’s a contradiction, as any play has gone, and therefore not aiding at all?
If all the machining is of a high tolerance and fits "properly" then I see no reason at all not to do it.
My gimbal is very low friction, and has zero movement in it at all. If it can be shimmed, then why not just make it right in the first place?
I can’t imagine there is a massive difference in manufacturing cost between the Clipper / Ultra / V2 gimbals.

Respectfully,

Rick.

Richard-

No problem. It's just a different design. There is no slop in the orthogonal alignment of the three axes of the three sets of bearings, which is one thing that determines how the gimbal will function.

The "slop" is only along the axis of the set of bearings in the handle, and has ZERO effect on operating, as the axis remains true and square. The play prevents pre-load which could induce friction. Other gimbal designs may look the same from the outside, but work differently.

While we are on the subject, the alignment of the three axes is hugely improved by this gimbal design - a built-in hyper critical adjustment of the centering of the yoke (user-tool-included).

Thanks Jerry.

I was never in any doubt that the play had any influence on alignment; it would be nice to know more about pre-load tho…

Best,

Rick
