I'm just about to make the cutouts on my Four Pi baffles for the waveguides and ports. However, the dimensions in the Four Pi plans don't quite seem to match the dimensions of the actual waveguide. From the plans it looks like the edge of the waveguide should be 1.75 inch from the side of the box, and that the waveguide is 10.5 inches wide, but my waveguide is actually 11 5/8 inches wide. From some quick math it looks like the center of the waveguide is supposed to be 7 inches from the side, which makes the edge of the waveguide 1.1875 inch from the edge of the cabinet.
