RE: [TCML] rotary gap disk

["S&JY" <youngs@xxxxxxxxx>]

Jay,

There is another good and cheaper alternative to G-10.  It is GP03, an
electrical grade fiberglass material, available from McMaster-Carr. It
machines well with ordinary tools, and has a temperature range up to 400
degrees F, which is better than G-10 if I remember correctly.  I use it in
my RSG and am very satisfied with it.  In 2000, a 12" x 12" x 3/8" sheet of
it cost $9.73.  Look at their Part Number 8549K372 to get you to the right
page in their catalog.

I am not planning on pushing tons of power through this thing. About 1 kva
from my obit stack.  
I tried looking for cheap G-10 again and was unable to locate any.  oh well
When I am out of college and have enough money to buy a pole transformer I
will probably have enought money to buy a good motor, G-10, and tungston to
make a really nice gap.  But for now this will have to do..  
I like the idea of using washers as heat sinks on the flying electrodes.  I
think I will use that idea if I have room for more weight.
I modifyed the motor today but I have no way to test it for actual sync
rotation untill I get home for christmas break. Unless someone knows how I
can do this without a florecent light.
thanks,
Jay Howson
