Mr. 1943, you're correct, this does slay me, but thinking about it now, it's this narrow width that permits cutting. the tight curves.
The aspect I find most impressive is the absolutely straight cuts, keeping the lost wood to the width of the blade kerf, thus such nice grain continuation from case straight across the drawer fronts.
Very nice work.

I have to admit, the straight line cuts are a credit to my fence but the thing I find cool is that the drawers are cut with 
one entry cut  -  that's why there's an open V in the center, that's where I cross over to make the second drawer.
