Step 6: D-Pad
It needed a 6mm maple edging though. So I made a template off it using a flush bit in my router, then I rebated off the template with a 6mm rebating bit.
I thicknessed some maple to 6mm and worked it to surround the cross.
Then glued...clamped....sanded flush
Annoyingly, the oak I used for the cross looked completely different from the rest of the tabletop. I recommend just making a 6mm channel and filling it with maple instead.
