@markscoffman
Thanks for your comments.
I have to agree with everything you said.
I am intending to take small steps with this and use materials and magnets that are known to work. One  have something opperational I will then progress one step at a time to change things up (like using neo's) if the device I have seen pictured constructed by Smokey2 can run for 3 hours I am sure with some good engineering like you have suggested it could run indefinately. This in itself would be a significant break through.
the thing that intersts me the mosif if the magnets (especially if I can get a device running with neo's) will degauss. That question has always facinated me but I have never found a working magnetic motor that I could test the theory on.
I am working on another project using magnets and gravity when I got side tracked on this.
Kind Regards
Mark

@smokey2 or exxcommon
I appologise for my ignorance in addvance.
Since I decided to allow my self to be distracted and have a crack at this could you point me to the design criteria for the linear bearings.
Kind Regards
Mark

@sm0ky2 - Thanks for the explanation, a real eye-opener.  Yes your wheel's operation is definitely different than I had envisioned it - definitely more clock-like than wheel-like imo...

.....
The "latching" strength of the unbalanced arm of this wheel
locks an arm into position by centrifugal force, so the more RPM
the stronger the latch, but it then takes more magnetic strength
to pull the arm out. Sounds like possibly a job for a dynamic RPM
vs distance feedback mechanism actually, but first things first.

:S:MarkSCoffman

Dunno, I must be doing something wrong 'cos my experiments indicate that for a given magnetic field strength (how far the magnets ramps are from the rotor magnets) and at low rpm's, (again hand-powered but much faster than sm0ky2's self-running speed) therefore low CF, the weights latch powerfully.  Increasing the rpm's sees CF acting counter to the magnet ramps till they no longer are able to lift the weights...

the magnets ive had success with have all been (black) ceramic ferrite. 1-inch round, 1x3/4" rectangle,  1x2" rectangle, and one combination using the 1x3/4" ceramic, with neos on the back side, but im not sure what affect if any the neos played.
The ones currently on my my build are 1-inch x 2-inch x 1/2 inch rectangles, and ive been using them in stacks of two,
so the "magnet" is actually 1" x 2" x 1". They show no sign of "weakening" thus far.

concerning the "force" to get it working,. if you mean the force the magnets apply to the rod(?) - then that would depend directly on the mass of the rods. If you mean force the kick-start the machine itself, the answer is almost none, when this is properly tuned, all you have to do is line up the first rod into the array, let the magnets lift it and gravity takes over from there.

about the only time i give it a hand-spin is when im trying to diagnose a problem with one of the rods. but usually im holding it steady, and turning the wheel slowly one rod at a time, to find the little glitches, then adjust the magnets apropriately.

@Mark Coffman

the "backplate" is made of a steel alloy very similar to what you find in a low-frequency transformer. "E-cores" and "H-cores" are what we call them, this stuff i cut from a utility shelving unit, but the two materials are very close in composition. I've used cut pieces of this stuff in several magnetic experiments, and even in the long term, it doesnt seem to retain any magnetism at all.
at least nothing strong enough to be detected by the viewers or iron-dust/filings.

as far as "erasing" these ceramic magnets,. these are hard black ones that look like graphite. like what are in a microwave.
it would take quite a bit of energy to re-write them. much more than Heinrich Lenz could account for. they held up a floating table by 4 corners, for several months and i cannot distinguish those 8 magnets from the other 42.

i dont know where you're going with the wood thing. are you saying that the plant-cell structure, is some-how compromising itself, by transfering energy from the wooden rod in motion, into the A, causing additional propulsion?? and that in time, the very structure of the wood will break down, once all that energy is used up???   that's kind of "out there", i wouldn't even know how to approach that problem. and thus i am in no position to refute it.

personally i do not think the structural integrity of the wood is supplying energy into the wheel, i dont see wood breaking. i see glue breaking.... mostly blue plumber's glue, for which im contemplating an edequate replacement.  that and if im going to go through the whole re-glueing process, what little fixes i can make while im in there... and no the glue is not supplying energy to the system, it just sux.

and im not sure about the energy crisis. what could you actually extract from this? the small difference between the time-reactive gravitational force, and the time-constant magnetic force?
the only variable there is, of course, Mass. Solution: larger wheel, more magnets, more mass.  in the end, you would have an entire field of dozens of gigantic spinning noise-makers. and the logistics of transfering that momentum into "work" would seem to prove futile.

my hope from this, is that it "clicks" in somebody's head the reason WHY this works, and from that something useful can be created.

like something more "sword of god-ish" has hopes to create real energy, this wheel is a toy.
the way i understand this wheel to operate, the difference between not being able to lift the rods, and the rods being lifted too strongly and getting hung: doesn't leave much room gravity to do any "work" during those moments. now,. once gravity pulls the rod out of its magnetic hold,(which is followed by a short magnetic kick of repulsion heading out of the field) the arm falls for a bit, and it is during this time, you may or may not be able to use some of its momentum. remember now the wheel also has to push the next arm into the magnetic field so you cannot take more than it requires to operate. i just really dont see this as having a great deal of "extra energy".

you can change the angle at which you lift and release the arms, mine has changed several times and that doesnt seem to matter much. but i can see how it would if you are trying to get juice from it.

a lot of it has to do with how heavy your wheel itself is. the arms just create the propulsion mechanism, its the spinning mass of the wheel that makes this possible. if you have a balanced wheel, you don't need much weight to get it going, and it will have quite a bit more energy by the time the off-set weight gets to the bottom than you would get by dropping said weight. yes the small weight would be going faster, but when you're dealing in Newtons, its all about the mass.
That's why i give my magnets a mass rating. i.e. how much mass can two repeling magnets lift vertically. so i know the limit at which i can add or subtract mass from the rods to attain the proper proportion.   

If you're building one, you dont want the total mass of any of the rods to exceed or even come close to the maximum mass your magnets can lift. you dont want the magnets to have to "fight" to lift it. what you're looking for is for the rod to enter the magnetic array and just easily ride the outer edges of the field upwards as it spins. the wheel is slowing down during this time, as the mass shifts over to the other side. you want the whole thing to be a smooth transition from entering the gate to pushing the rod out.
you can "feel" it as you spin the wheel slowly into position.

@smokey2
thank you for the info on the magnets, I really appreaciate that. just one last detail, the linear bearings that exxcommon devloped, I have been through the thread for hours and could not findthe description.
I want to get as close to your design as possible and then do variations fom there.
Kind Regards
Mark
