Does jumping up and down on the floor make the shakes worse?
(Get someone to do this for you while you watch.)

I've only ever used Narashige or modified Huxley manipulators -
no shakes with them.

Do the shakes happen all the time, or just when you are moving
the electrode? Does the micromanipulator have servo motors? If
so, what happens when they are powered off?

Do you have an A/C unit blowing air round the room?
