Working Attraction Magnet Motor on Youtube!?

Magna,  you didnt grind your screws close enough on the outside.

The screws need to be completely flush.   Meaning,  the head needs to be level the
the diameter of the start of the tail.

The other replication was even worse in alignments and had no grinding at all.


Actually, I think he did say that he hid the head with a hammer - which may have
caused the screws some magnetic fields.  Hard to say really.


Edit:

Sorry Clanzer,  but Ive watched the Vid full screen from a saved file.   There are 4 revolutions.
Ive counted about 10 times now to make sure.

I used two points as references.   The inside wall of the tube has some word written on it.
The other times I watched the inside of the hard drive bearings... following one of them
carefully.

Sry for the bad quality, its from my phone.  I know I don't have the spacing correct,  which very well could be the problem, but I'm not getting much pull in any direction from the screw.  It tends to want to stick at the point and head, but that doesn't do much.  I gonna try and find some premade triangular pieces of metal, if I can.

Freezer, theres No way your gona get any pull with the screw heads so
far apart from each other.   

Also, while you have ground them down well on the outside,
your tube diameter is so small - and the screws may be too long... that they
protrude too far from the base at the points.

If the tails stick out too far - or are too long,  the fields wont fade...
thus it will get stuck on the one screw and wont change places
with the next screws head.

  Also, I notice your platform is thick and heavy looking.  I doubt
you will move that with those magnets strength.

Almost done. I went to my shop today and spent about 3 hours grinding those screws (and a bit of my fingernails). I Just finished mounting them on the cylinder and it looks really close to the video. I left my cylinder longer as I may try putting another row or two on later. The screw size is #8 x 3/4 and I believe I have them ground the same way as the vid. My cylinder is the center of an old plastic wire spool that is exactly 3.5" in diameter. Looks very close. I just have to get some magnets now =(.

I already know it doesn't work.  I'm gonna try and find another approach. However I don't think its the distance, its the shape and size of the screw, which I think makes the difference, but feel free to try.  The bearings in it are real good and the slightest force moves it.   I also have a variety of n42 and n50 magnets and they have plenty of pull.   I just posted to show my failed attempt as some requested.
