Excuse me, My point had to do with the expected life of the motor under the conditions it was designed to be used in, verses the life expectancy of the application to which is suggested in this thread. In practice the component that fails is the bearing at the business end of the motor.

I've attached the 3d dxf of the modified base for your amusement. Please don't ask for g code. My final design removed material around the base to lighten it considerably.
I better stop here -- this is getting waay off topic!
