Nodebundle for playing with nodes

Hi all,
I have been working on the Bottle Feed Screws and was wondering if it was possible to animate the rotation of the screws with the node editor for a visual check.
I have managed to rotate one screw with a widget knob and that works ok but the second screw which is parallel to the first screw rotates about the world X axis not it's own axis (the first screw is on the X axis).
Also the screws rotate in different directions one left hand one right hand.
So my questions are how do I set the axis position of rotation and having tried to enter negative numbers in the slider to reverse the rotation direction and failed how to have a clockwise and anticlockwise rotation.
Ideally one widget knob to rotate both screws.
Thanks
Barry
