Tilted Dial Rotation Spinning Faucet Dials are easy in blender when the axes are in default 90 degree space, but I have a faucet with tilted dials and I need to rotate them for animation, but I can't figure out how to rotate them like you would expect them to without them getting all contorted. Can someone please fix my blend file so this works correctly.

You need to change the movement type for the transform manipulators to "local" instead of  "Global". This changes the movement to correspond to the object's position/rotation. once you have done that and put the menipulator wigit to "rotation" it should be easy to rotate the faucet handles like you want.
