Steve,
The rotary wheel is 10.0" in diameter. It is made of 3/8" lexan and mounted
directly on the motor shaft. The electrodes are 1/4" x 20 stainless steel
acorn nuts mounted with external tooth lock washers in 1/2" from the outside
of the wheel. The motor is a 1/2 hp rated at 10,000 rpm which is too high
but I could not find a 5,000 rpm motor. It is a universal wound motor which
has separate armature and field windings and can be ran on AC or DC. I use
straight AC with two variacs in series. One limits the maximum rpm and the
other I use to slowly bring it up to speed.
