 Justin,
 
 Those flats should be definitely wide enough the way it is.
 It should lock up.  The slight warmness is normal.  Are you
 saying you see the pattern rotating then?  Is that how you
 are determining that it's not locked up?  Some folks have
 trouble seeing the pattern at first.   It can help to run the
 motor on a variac, and as you turn up the voltage, you'll
 see the pattern change, and hopefully lock at a certain
 voltage.

Justin,

Also, as you turn the variac up, the tone of the motor will change.  You will 
hear a variable frequency as it is hunting, then finally a steady tone as the 
voltage gets high enough to lock in.  My motor locks in at about 100 volts ac.
