Nice sequence. I’d make one suggestion though: If you screwed the knob down to a sacrificial board to cut the finger recesses, couldn’t you just drill one, rotate it, and drill the next?

I am looking now for excuses to make a few of these. Thanks for posting it. Have you tried this with Baltic birch ply?

Kindly,

Lee
