Now Im here. It is very sentimental to me.

Good.  Tap into that emotional drive and keep flogging the rest of us on.

Passion is power

Im just imagining using small stuff to accomplish something here.  Say 1 to 2 in. copper washers, neo flat ring mags, 10 or so in series connection.  A lil baby homo.  lol   But it would be an easy, inexpensive way to experiment.
To get results, it doesnt always have to be big and expensive, hard to make deal.
Lets say it put out 10v at whatever huge amperage, a 10v motor to turn it. Bam Whos yo Grandaddy!

I ain't for certain you'd see much voltage at that small a diameter.  I have Cu stock to make a 10" disk, or 34" disk if backed with Al.  The PM field will be 7", all parts in stock.

Just gotta start drillin' and millin'.    Other things in the way for the next week.

Won't get any more time on this project till after the 11th

True that on the voltage turtle. I was just dreaming a bit. =]
Its worth a go though to see what we can see.
I have some big mags from a subwoofer, they are about 8 in. outer dia and 4 in. inner and 1 in thick. I have to take them apart by soaking is a solvent.  But I will try the lil one first to get things going.

Have a Few Questions and there are so many pages
simply asking might be the fastest way to get answer.

How hot does a faraday disc get?
With eddie currents, or otherwise?

How hot do the bearings get?

Does the current have any effect on conductive bearings?

Would plexiglas hold up to the heat?

Would plexiglas/plastic be better than a wood housing?
I've heard in some cases wood can indeed conduct electricity
and if I try to incorporate HV, I don't want to take chances.

Thank you
