These stools seemed popular this Christmas, so I thought I'd post a few shots of the process and end results. The top is 8x15x1-1/4", overall footprint 8-1/2x8-1/2x15-3/4. Legs are splayed 12º in two directions.
To get the tenon to exactly fit (.003 smaller) the hole, I had to use a metal lathe. Here's the videos
Marking the centers
Cutting on a metal lathe using a 3/8 bowl gouge tilted toward the headstock slightly to get a good smooth cut in a single pass.

Here's the still of the setup. Too much light washes out the actual leg except for the bottom.
Closeup
Drilling the holes. A framing square is used as a stop. Table is tilted to 12º
Blurry closeup shot of the drilling
Custom made v-block in the tenon jig to cut the slot for the wedge
Work in process
All eight finished
