[TCML] rotary gap disk

[Jeff W. Parisse]

Jay,

Keep looking for G-10 or change to a propeller gap. The Lexan will soften 
when the electrodes heat up.

If you MUST use Lexan, use large (sometimes called fender washers) and small 
(sometimes called SAE washers) brass washers to build up cooling fins on 
each side of the threaded rod. Top off the stack with the acorn nut (brass 
cap electrode).

Remember that your 1/3HP motor is going to be a 1/4 to 1/5HP after you have 
modified the armature. You may want to weigh your parts and do some math to 
determine if you can spin your rotor at 1/5HP before you start cutting 
stock.

Jeff
