Best way to prevent joystick shaft from spinning?

[millercentral]

Question for you guys. My cabinet has a couple of Servo-Stick (JLW-like) 4/8-way balltop sticks that I love, but one thing that bothers me is that the shafts can spin around fairly in your hand. Doesn't really affect gameplay, but annoying. I'm not looking to add rotation controls to the sticks (I already have spinners elsewhere).

Any simple techniques you can recommend to prevent the shaft from spinning around, without inhibiting any other functions?

Thanks!

All sticks do that. You don't really want it to be too rigid.

Yeah, mgb is correct. You'll get used to it.
