Boolean trouble

This is driving me insane. I’ve attached a blend in which I am trying to cut the intersection of circles out of a plane. I’m using the Boolean modifier and trying all variation including intersect etc but nothing good happening. I’m following the tutorials to the letter but still no good. Anyone know what I’m doing wrong?

Exactly. What am I not doing?

See demo here for your blend file http://screencast.com/t/xccNjmMAptQl
YOu should also clean your mesh up. Why are your objects so large, you are getting clipping in the 3dview. Also reset the scale values back to 1 (Ctrl+A / scale) to prevent further problems.

Great. Thanks again Richard. The model is this large because it is being cut on a cnc machine to these dimensions. The scale is at 1 as far as I know.

The scale is at 1 as far as I know.
No its not in your original blend, far from it. I corrected it in the blend I attached.

When I try to scale the dimensions also change
