Indicating the edge to make the slots roughly horizontal.
With the 4mm direct collet the head won't go low enough on the column to let the cutter reach the table, so I've had to raise the case a bit. I know this is a terrible setup, but it's a one-off.
The best I can do to hold it in place.
Making the square aperture and associated holes.
Making the hole closest to the edge. I had 146mm usable X travel and needed 144mm of it.
Finished.
