Overbalancing wheel

[Rafael Ti]

Here is a link to a drawing (because my computer refuse to upload pictures). It explains what forces one must consider when designing an over balanced wheel.
The green arrows shows the torque gained and required in a given position of the weights. Blue arrows is force from wind. Light blue is the required acceleration of weight C to keep it syncronized with the rotation.

I hope it clearify some issues to consider regarding so called overbalanced wheels.

Vidar, my drawing was demonstrative only. I can't believe you took it seriously... I realise that the shape of tracks/patches the weights move along plays a very important role and... is probably a key for working OW. Yes, green arrow nearby weight 'C' makes a problem, but there is a way to decrease this force. But... green arrow 'B' should be around 4 times longer than green arrow 'D' (the gain from leverage) - on your drawing is only twice longer...
Thank you for your time and explanation however I am not convinced you are right. On my drawing u saw a typical example of wrongly designed tracks, but as I mentioned it was only for illustrative purposes...
Also I believe that correctly designed tracks can help to utilise centrifugal forces to push weights onto falling side of wheel. That may be a secret of SJack Abelling solution.

Il est pathfinder. J'aime son travail. Tres bon, n'est pas ?

Vidar,
        The enhanced drawing of mine that you submitted, is quite easy to explain:  When you look at the 'arms' that constitute
the weights themselves, then the 'arms' in the top half of the drawing, are, in fact, extensions of the weights themselves, which
are shown as being twice as long as they need to be, (shown in various parts of the drawing).   What happens is, instead of the
weight proper, 'sitting' on the center circle of the device, and then 'hanging' from the outer-rim (large-circle), as IT (the device),
rotates ---------- the extension arms do it!
The weights proper, DO sit on the bottom of the large outer-rim, but 'hang' from the bottom of the small inner-circle (6 O'clock
to 9 O'clock).   When the weight, in the 9 O'clock position, is in place, the weights extention (an 'arm') follows the shape, almost
of an arch, of a device, used to keep the weights upright!  This weight, cannot be counted more than once!
As each weight reaches the 12 O'clock position, the extention-arm, goes from sitting (with the weight), on the center circle,
and attaches itself to the 12 O'clock position of the large outer-rim ----------------- where, once again, the cycle begins.
In the original drawing, submitted to Vidar, the extension-arms, are shown as dotted lines, and is much easier to understand,
perhaps when he gets his computer fixed ----------- he'll show you(?)

To Vidar, #259
                        Vidar, just what is it , that confuses you,  everyone else seems to understand it?   I fail to understand, why you
think everyone else, doesn't understand it either!

Once again, I'm asking if any one of you, would resize a drawing, and notes, and make a 'post' for me? I'd like to do it
myself, but I was told my lap-top can't do it, plus, I'm almost blind.   The man I usualy get to do this for me , has died!
BTW, this 'new' post, has nothing to do with THIS post.
Thanks for your time!

BILL.
