Grinding flats into motor to make syncronous help!

I'm trying to convert this motor to syncronous operation. I am not 
sure how big to cut the flats. Picture 3 in terrys zip file shows the 
flat going to the edge of the next pole. Yet the motors 2 picture in 
the same zip file says measure to the middle of the next pole. What 
should I do?

Here is a picture of the motor:

Is the black area the dead pole? The red ones dont have direct run 
windings around them, but they are totally encased in the windings, 
which is what I think matters correct? The black one is inbetween the 
2 loops of windings which is what I think I want...

Is that the correct distance for the flat to be cut? Half way between 
the next active pole? The armature is ~ 3.5 in diameter.

Thanks guys

PS: Terry, can you email me your phone number, maybe we can get 
together sometime again.
