Use a solvent like acetone or alcohol (better than 91%). Put in small container and shake around. Dry well then apply a couple drops of a thin lubricant. Fishing rod reel oil or 3n1.
You might remove the races to clean them better.

Given your latest observation of a new stopping azimuth, I think you're going to have to take a lot more observations to establish a statistically significant preferred stopping azimuth. To visualize any trends as they emerge, you might consider plotting your azimuths as they come in on a rose diagram -- basically, a radial histogram (see Wikipedia if unfamiliar).

Given that we have still have no agreed-upon physical reason to expect a preferred azimuth, this kind of care is especially warranted.

The fact that you observe narrower spreads in stopping azimuth over shorter time intervals raises the possibility of a Coriolis effect akin to that behind the Foucault pendulum. I think that's pretty unlikely given the short length of your suspension rod, but we're already grasping at straws.

Q: What is your latitude?

Foucault pendulums are notoriously sensitive to even the tiniest of lateral forces applied to the bob at the time of release. For that reason, they're often pulled back with a very thin string. Once the system settles back down, they're then released by burning through the string while under tension. Have you tried that?

Another hypothesis worth considering: Pesky aliens parked in high-Earth orbit polarizing the subspace tachyon field just to mess with you. I read on the Internet that they do stuff like that all the time. 

Hi,

To clarify on efficiency calculations: I divide the rpm reading of a certain minute by the rpm reading of the minute before and make a percentage to find the efficiency of that minute. Example: 1st minute= 1000rpm, 2nd minute= 800rpm. The efficiency of the second minute= 800/1000 = 0.8 = 80%? Thanks.

Yes. At least, this is how I do. 

Since you continued to have the same two preferred resting points of the wheel, even changing the position of the static magnet above, and that of the little magnets, I would say that this seems a strong clue that the magnetism of Earth is involved.
And, if so, maybe the eddy currents are not necessary to explain this phenomenon.

It is puzzling, it seems like the wheel behaves like the needle of a compass, but with two north poles at the opposite sides of the wheel, and two south poles at 90 degrees far from the north poles, (would this be possible ??)

Maybe, if you touch the circumference of the wheel all around with the tip of a knife, you can feel which sides attract it more.
You could see in this way how many poles there are around the wheel, two, (or four !?)
 

what I mean by fine tuning the magnetic pull is that I constantly have to increase the opposing little magnets because of the magnetization, after another minimal initial push test ensuring, the magnetic pull was only just sufficient to carry the weight. The same happened approx sector of 10 degrees of back and forth movement, also a new stop direction north-west - I'm baffled

Not sure what you did mean here.

I'm wondering if that name spun into the Lady Walker that I was in search for a month back? That was from the late fifties--early sixties.

I don't know. Maybe.

By the way, it seems that you were looking for tops not necessarily wider but taller.
Elongated tops, say 1.8 to 2 inches wide by 3" tall, were available in the 50s. The Fli-Back brand for example.
I'll be on the look out for your Lady Walkers with ball tips.

Hey y'alls,

The bearings in my QSH starts to lock up and spin less good... How can I clean them ?

Thanks

Hey Ta0,

I'm wondering if that name spun into the Lady Walker that I was in search for a month back? That was from the late fifties--early sixties.

I'm still lookin'....

Wow... I too am in shock.. this is *AMAZING* =)

I need to work more on my koma skills... =)
