Working Attraction Magnet Motor on Youtube!?

[ken_nyus]

Be careful heating PVC up, I understand the fumes can be dangerous. I try to use hand tools only with PVC.

Wow Ken.. I was just going to write back with that. yep. Melting PVC fumes are really bad... Drilling 50 or so holes not that bad. Just a bit of time but could help the placement of screws a bunch and keep your health  .

If this really works I got some more ideas for improvement. My biggest concern is that the hard drive platter is adding a major part in this. Time will tell..

Later,

very interesting concept, and i i'm up for replicating it. As people have said , the only reserations i have are the lack of good sound, and the hard drive bearing. In good faith i assume that the hd bearing has been gutted of the motor contents. But if it does work with just a gutted hd bearing which after much experimentation is not the best bearing in the world it should work with practically any bearing.
It occurs to me that the screws could be replaced with triangles of steel, or the sprial rotor . Still trying to understand where the sticky spot has gone tho..lol

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?

Better still. If you want to use PVC just drill a large (head size) holes where the screw head would go. No grinding screws and the placement would be more exact. Just lay the screw in place with the head inside the hole and add a bit of PVC glue.

Hi Tom

Yep, if this is for real and no trickery has been used, then very interesting indeed. I wish the video had been shot with atleast a bit of voice over to rule out any of that sort of stuff must admit.

I think even drilling the pipe for each head would be a long job, seems there is probably about 40-50 screws used there. If PVC pipe is the only option, then another method could be to mark your PVC pipe with lines and then heat the screws up, so as they are placed, they melt into place as such.

Easier option would be to get angled shafts of metal and simply stick them on,but trying to think what would be suitable.

Try horseshoe nails, they are flat and just the right shape if trimmed. They are also the right kind of material.
