Hi Paul; Thank you for the complement. The motors are sewing machine motors.
Find a sewing machine repair shop nearby. Most of them will sell you a used
motor for around $5.

Hi Doug - excellent workmanship!
I built a homemade VDG generator too and it will shock me from about 18"
away.
Mine uses a bedframe castor attached to a oscillating fan motor and it turns
a belt made from nylon stockings over a teflon rod (just friction - not a
roller). I use little metal screen patches as my pickup brushes. They
don't touch the belt, but they seem to do an adequate job nonetheless.
Where do you source your motors?
I am just putting the finishing touches on my first Tesla Coil at the moment
too and am excited to try it out. These things are funny (kinda like the
VDG generator) - you invest countless hours on it, not knowing if your are
going to get an ounce of satisfaction from it. Hopin' for good luck on the
Tesla Coil.
Thanks - Paul

Hi Derek; What you see is
conductive plastic film riding on the rollers
attached with copper tape, rollers are PVC and
aluminum tape covered
acrylic. I did do
comparisons, plastic film produced 30% more current. Belt
Is neoprene.

Doug,
From what I can see from the
videos, you are using a thin piece of
copper
for your pickup. Have you done any comparison between that,
wires
or gauze. Do you see an increase in
current or voltage ?
What
is the composition of your rollers and belt ?
