[Dafni]

I always do it like you, viruss. Grind a flatspot into the shaft, and crank the pinion setscrew as hard as possible. I don't even put threadlock on the setscrew.

Let me see your hands in the air, boys, if you do the same!

Be carefull when you grind the shaft! Don't let the metal shavings enter the motor! Cover it up.
