Festool Carvex Circle Cutter, Part 1 - Setting up the 'Attachment'

Boys and Girls,
After making the video of my "Fe$tool Carvex Benchtop Attachment" (Parts 1-3),
.... I couldn't just leave it at that and thought I could do more with the upside down mount.

The thought of circle cutting came to mind and this Part 1 of a 3 part videos tell how I managed to turn it into a circle or a hole cutter as the available Festool attachment use is only shown for "Radius cutting" against open edges and no one seemed to address using it to cut accurate circular holes using the jig.
