Hi again, 
      Ok, your replys on that cent. switch made a lot of sense to me. So I 
popped the motor apart again (after 6 times, one gets pretty good at it :-\) 
and looked at the contacts on the motor, and the centrifical switch on the 
rotor. Both looked good, but I still cleaned them up. 
      Also, when taking the motor apart the first time, I noticed a seal or 
something laying on my work area. I couldn't figure out where it went, so I 
put it in the housing end, in what looked like a seal area. I guess it didn't 
go there, because that was what was causing some of the heat, and -100 RPM. I 
know this because this last test, without the seal, didn't get hot, and was 
clocked at 1725 RPM. 
      I know the switch is good, because I saw it spark as it kicked off. 
For those of you not keeping up, this motor has flats, yet is running at 1725 
RPM (what it is rated at). 
      I also did the carboard circle thing with flourecent light, and it is 
noticeably out of sync. Do I really need a variac to fine tune the voltage? 
I'm not worried about phase shifting as of this point. I just want this dang 
motor to run sync.... 
      Also, a couple questions: 
       
      1) would a 1/2" x 6" lexan rotor be ok? 
      2) what can I do about excessive endplay? 
      3) what kind of supports should I use to hold the stationary 
electrodes? 

I'm sure this thread will live for a while  :-D
