Note that reversing *either* winding (but not both) will reverse the motor.
Hoooraaayyhh!! I have made my motor rotate clockwise! At past midnight, I have achieved success! The principle is actually easy. Thanks to John Hasler and RJSakowski, I ended up flipping the start winding. Initially, it was intimidating for a motor newbie like me to rip into the motor and windings but focus and making the effort to understand your advise helped me figure it out.
I'll be firing up my home built belt grinder tomorrow on her maiden voyage to see if everything works. All will be made possible with the motor now spinning the right way for the machine. If it's serviceable, I'll post on it at the Beginner's Forum. Thanks a million, guys!
