RE WhipMag history/construction and parts:

I find this large PDF to be the very useful.  It appears to have all of the dialog between Al and OC, as well as specs -- as they evolved.

... http://www.ospmm.org/whipmag/pdf/OC_motor_012708.pdf


Cheers,   

Yada..

@Yadaraf,

@overconfident's input is to be ignored altogether. It's only noise and gets in the way of proper replication of the device.

Incorrect -
I am not using Stewart-Warner Bearings for my Stators

Correct -
Order Stewart-Warner bearings of correct size from Mike, the bearing guy.

Small progress is good!

Cheers,
Bruce

@Bruce
I don't remember Al writing anyting about the Stewart-Warners beyng for shure the ones that worked properly as stator's bearing between the 13 he had, since he had some Stewart-Warners , but not enough of them , so he bought some other unlabelled ones . so is a good start knowing the maker of some of them but isn't shure they are the good working ones , at least not that I remember him mentioning  it .
just a notice 
keep the great work up

Hi Andrea,

Nope, look again at what he says.   

Al:
"I had 8, they are Stewart-Warner, and I had to buy 5 more from another source, they are unmarked."

I interpret this to mean that his original source for the Stewar-Warner bearings was dried up and he bought 5 more from another source.  (but still the same Stewart-Warner bearings).  And when they arrived, they were unmarked.  Thus no serial numbers, etc.  My bearings are all unmarked also. 

Cheers,

Bruce

EDIT:
@ Ken
Thank you.  I will try Stainless Steel 4-40 from Lowe's.  I should not have to grind the head.  Still Stainless Steel.  I also need nylon screws for my dampers, not the brass I have.  Everything affects damping, magnetics etc. and as Omni has said, it must be tuned perfect and built/replicated perfect.  Only one on the planet works.  I take this very seriously as do many of you.  Let's make this happen.

@Bruce
Well better like that then 
I must have miss interpreted what he meant .
Cheers
Andrea
here you find nice and clear pics of the device :

@Bruce_TPU,

That's splitting hairs. I also understand it the way @AndreaGanora understood it--he ran out of the  Stewart-Warner ones and had to buy 5 more from another, non-Stewart-Warner source and he doesn't know what exact source that was because they were unmarked. Now, if Stewart-Warner produces also unmarked bearings these new ones very well might have been Stewart-Warner as well but there's no proof for that. The only hope would be if Stewart-Warner is the only Canadian company producing bearings. Etc. ..., etc. ... I think we're trying to read too much into what @alsetalokin drops laxly here and there.

[Omnibus]

What should happen is to ask @alsetalokin to replace the parts from unknown sources with parts (magnets, bearings, screws etc.) of known origin and tell us if he still reproduces the effect seen in his first video. If he were to publish this in a peer-reviewed journal he would be asked to do that by the reviewers. Otherwise it's just a frivolous playing a cat and mouse game with those genuinely interested in this experiment.

That's why I'm saying again, given these unfortunate circumstances (the "author" not willing to abide by the scientific standards) the credit for constructing this device should go solely to the person or persons who would really  find out the conditions for independent parties to easily reproduce this effect.

[Bruce_TPU]

@ Omni
Perhaps.  Perhaps not.  If I know a particular Mfg. Bearing works, why would I want another?  I would have started with those, if I had known the name.  And it is a Mfg. of bearings.  I will find and order some tomorrow. 

I'll post the info for those that want it.

@ Ken
Is the SHCS screws that you have magnetic or non magnetic?  Some stainless is, and some is not.

Please verify and let me know.  Thanks!

Cheers,

Bruce

@AndreaGanora, that is an intrigueing and complex theory, however a few pages back, I think we determined that Al's balls are ceramic. 

< pictures a bearing within a bearing with ceramic races and magnetized balls running itself > [ someone wanna do the math on that one ? ] 

@JFK
Apart from jokes and from my "Magnetized Bearing?s magnetic vortex and delayed tailing effect"    wild teory  , I've based my two actual replication's rigs  mainly on the infos collected in a pdf file downloadable from OSPMMdotORG where are included lods of infos posted mainly by Al plus some others on various wipmag treads over at steorn and elsewhere.

There you can read Al's stator's bearings description  :
Stator bearings -
I had 8, they are Stewart-Warner, and I had to buy 5 more from another source, they are
unmarked.
Bearing is generic ball bearing, ferromagnetic, 0.500 x 0.1875 x 0.125
(Editor's note: If you look at the photos it is obvious the bearing is
0.500OD x 0.125ID x 0.1875H )
Mass of stator magnet assembly, including holder, magnet, and bearing:
10 grams. Variation between the 13 units is below the resolution of my (home) scale. 
 
@ All
here is the updated Pdf file,  it can be a great  help to go trough the various setup changes Al's operated  on his rig :

Cheers and good luck everybody

Hello Andrea,

That bearing information is VERY useful.  I am meeting with the bearing guy tomorrow.  I will try to track those down.

EDIT:
I wish we had the height from the top of the base to the top of the rotor.

Cheers,

Bruce

Also, there is info. there on what is included in the 258 grams rotor weight ("including magnets and shaft adapter, but not including shaft or bearings"); what the composition of the rotor spindle and bearings are; etc.  All the stuff Omni was looking for, I believe.  Invaluable document!

[Bruce_TPU]

Hello all,

I have just labeled this picture.  This is what I need to now work on, while I await my rotor.  It should be here this week.  It has already been shipped.

When it arrives, I will weigh everything and post the weights.

G'night,

Bruce

@ Bruce, Omni and Others

Was comparing my stator referencing Rotor magnets orientation to the attached Pic and could not come up with the same. Was wondering if u could look at your Orientations and supply some feedback.
Q.- Did Al accurately mark the N & S of his Stator Magnetics ?

Thanks
