No problem, Jesus!

Did you see the very inexpensive materials that went into that?
I did use a wafer thin neo magnet in the center to hold the axle.
The axle is a sewing machine needle which I drilled through a coffee stirrer and hanging from an old thread spool that I hot glued to a scrap of wood.
This is a 'world' axle. It means anyone in the world can make one.
I used a lubricant on the needle to neo connection as lidmotor advised.

I will be working to find the best place for the reed switch today, so there will be more later.

thanks,

jeanna

Lady @jeanna

It seems that I am a very visual person and to understand some things I need a drawing.
Could you make a rough drawing of your "World axle" ?
By the way congratulations lady.

Jesus

Jesus,
I think you had it. Since I didn't understand the thing in the middle, I removed it and here is a mod of your drawing.

Thank you lady @jeanna.

That was what I understood with this directions posted on this page.
******************************************************
1 Glue a magnet to the top and bottom of a small lid.  It's important that they be in the dead center of the lid.

2 Glue four small magnets on the edge of the lid.  It's again important that they be spaced evenly.

3 Let the rotor hang from a needle on the top magnet.  You should also place a needle under the rotor but not touching the bottom magnet.  It's just there to help the rotor stay stable as it spins.
******************************************************

The thing on the middle its supposed to be the rotor with one needle on top and another on the bottom without touching the magnet.

Then I saw the clips and understood the situation.
By the way I downloaded the five youtube clips explaining how to make the coil/battery.

What I did not see was the explanation of how many layers of the bifilar winding are needed bafore starting the secondary winding.

Jesus

He probably lost count! 

He did measure the diameter of the finished primary at around 2 inches, if I remember.
The test is the compass.
If you get some swing with the compass when you touch the inner of one metal to the outer of the other then you have a coil that will work.

But, that has not helped me to succeed, yet.
The rotor worked better last night without the reed switch than it does today with it.
grrr.

I added a cap in parallel with the leads for some extra punch. So far it has made the reed switch make noise (so it is working) but the rotor still slows then stops!
I also tried lasersaber's 2 reed switches trick and also with a cap, and still it slows then stops.

I am discouraged, but there must be someplace to place the rotor and switch that works!!
And, I will find it!
.... soon, I hope.
I have struggled with this coil since the winter of 2008. I am not about to give up, but this is very difficult.
