Working Attraction Magnet Motor on Youtube!?

I've created a sub-page for this project listing the replications that have been attempted thus far.  Feel free to post yours, or to elaborate on the description given for yours at http://peswiki.com/index.php/OS:Screw-Magnet_Motor:Replications

Of particular note, not mentioned at this forum yet, that I can see, is:

"I have had marginal success replicating this device. I have flattened all screws and positioned them perfectly. I have gotten over 360 degrees of rotation(which I feel is very significant!) I am using an old stepper motor for a mount, but a smoother bearing might do the trick, UNLESS xpenzif's design incorporates the small bits of attraction and repulsion that you notice in a stepper motor when you try to spin it manually. Maybe he staggered the screws to line up somehow with that effect. I PM'd him asking about this and I'll post his response, this could be a key piece of the puzzle."

Oops, major construction error in my replication. I forgot to flatten the outside heads. Good thing with hot glue: hot air to remove the screws again. Back to the work shop.

@klicUK,

Good luck in your replication. As for frictionless breaking system you mention, this has been a concern with Finsrud's machine too The supposition is that Finsrud's device is just a very efficient redistributor of the initially imparted energy. There are some very simple experiments which can exclude that possibility. Unfortunately, Finsrud hasn't been forthcoming in clarifying that issue. Here in this case, we would have grater possibility to conclusively answer this question after it becomes easily reproducible (this is a much simpler device anyway). Even at this point one may see that such a possibility (the device being just an efficient redistributor of initially imparted energy) is to be excluded--observe, for instance, the slowing down and then accelerating of the rotor etc. However, let's see the reproduction first and then discuss this issue.

Now I flattened the screws and I mounted them back on the PVC. Sorry to say that I still meet a sticky spot when any screw head is passing a magnet. My replication is still not working.
(I also have to rest the index finger of my left hand after hot glueing the screws a second time.)

Possible modification for this device....


Instead of gluing the screws on.  Why not screw them in. The process I am thinking about is screwing them all in to the head and then twist each other screw out a little bit more then the previous.   This would also help in testing out a couple of other setups without having to rebuild a new device.  Different configurations to test.  Lowest set screw to highest set screw around the full circumference and also trying lowest to highest that would occur 2, 3 or 4 times around the same circumference
