Working Attraction Magnet Motor on Youtube!?

I was brainstorming this and what about using cement nails instead of screws? They are tapered and should be able to be bent to conform to the cylinder. I have no time to try this now, but thought I would pass on the idea.

I cut a small elongated triangle from laminate steel and manually testing with a small nd40. Pull from large side is at least 5 times the pull from pointed side (just a rough guess). There should be no sticky point going from the 4th triangle to the 5th. Can easily slide to middle of triangle, so maybe the attraction of the next triangles large side will be enough. Can anyone Simm?

I kinda had the same idea.  I think cutting triangular pieces of a metal sheet might work in place.  I tried screws around a cylinder and couldn't get it to work.  I used regular 1" drywall screws and hot-glued them to a roll of tape.  I noticed in the video that the screws are not consistent, with the placement being off a bit.  I don't know if that what causing the problem.  I'm not sure if grinding down the edge of the screw will help.  I think the spacing and strength of the magnets will be a crucial factor.

@ xpenzif, outstanding thought process! congrats!

To those who are brainstorming a reproduction, please remember it's all about timing & sequencing. 

Start slow, with one attractor and magnet to determine how much "pull" you are getting, because each of your materials will react differently with "your" magnet.

I am building a base test bed with only one attractor to learn how this attraction model is working. After that I will adding additional atttractors 1 at a time to test the related pull vs counter pull. 

Thanks for the fun xpenzif

To those who are brainstorming a reproduction, ...

I'm collecting parts that are most alike the original design as possible. I want to replicate BEFORE I add all modifications since those modifications are always the reason that a so called replication is not working (see other replications on this board).
I just have a question about that HD motor bearing. I feel a slight resistance, probably since that bearing is a little motor. Can I use that bearing as is or did @xpenzif do something to reduce that resistance?

Thanks.
Eric.

I sure hope I am wrong here but something about this whole device does not seem right to me. Why is it that a verticle column of magnets being attracted to a collection of metal attached to a pvc tube can now suddenly spin. What happed to the stickey spot? It seems to have disappeared.
It was stated that the device ran all night. Would sure love to see it run continously for at least 1-2 minmutes (or more).
I am always an optimist but this one bothers me. I am probably wrong and it does in deed run as stated, but....
