Working SMOT ramp from Tom Ferko ?

Humm... The magnets out of a microwave might be good for this... They are 3-5 inches in diameter, polarized through it's face. Let us know how you are doing so we can start the replication process..

Hi All,

I finished the turntable with three huge 7 pound magnets on top of it with the South poles facing outwards and equal spacing between each magnet. 21 pounds total.

All North poles face inwards and the turntable rotates with the lightest touch.

As I stated before the four magnetic rails did not work so  the turntable donut magnets did not move.

If any one has made only the turntable as described they have not wasted their time.  Believe me when I say all you need is a SINGLE very small and powerfull bar magnet and you can rotate the  turntable by hand.  The poles on this small powerfull magnet must be seperated by about 2.25 inches.

I am in the middle of constructing a mechanical timing/tripping device that does the same thing I do by hand.  So far everything is working out.

If all works in the end then what we will have is a very simple self running motor consisting of 4 ( or 5 ? ) permanent magnets, a turntable bearing and one (or two) simple mechanical tripping devices. I might make two tripping devices when I see that one works

The tripping devices allow the small force of a single small powerfull magnet to rotate/controll the force of 3 huge magnets.  I have (9) .75 x .50x .25  neodymium rectangular grade 50 magnets stacked together that does this work. Small, powerfull, and light.  Bring that (by hand) near your turntable setup and see what happens !!

I will show how I constructed those mechanical tripping devices when my motor is operational.

You probably can figure out on your own what I am doing if you have already made the heavy 3 donut magnet turntable and can turn it with a fingers touch.  I will stay in contact.

Thanks for the update,
The mechanical tripping device is the hardest part. I wish you well on solving that issue.

Hi Mark,

Actually figuring out the mechanical tripping device came real easy to me.

Thinking just how to keep it in a very simple form using just basic cheap materials to construct it was the hard part.   I am past that right now and into testing and adjusting the device for maximum effect turning the magnet turntable. 

So far all is going well.    Tom

Hi All,

If you are going to use microwave donut ring magnets and put three of them on top of a turntable make sure you have an accurate weight scale and weigh everything.

If one side or the other on the turntable weighs more than the other you will have an out of balance condition and the turntable will fly into pieces if or when it gets to spinning.

Just like a new car tire needs wheel weights in several places for balance purposes you "MUST" balance the weight equally on the magnet turntable.   I got 21 pounds of donut magnets spinning true with a slight touch of one finger- and now with my mechanical tripping/timing device.         Tom
