The first run at this plate didn't go so well: see the "before" version on the left in the photo below. In my attempt to counter sink the holes for nut plates, the countersink bit walked and ruined the piece by decorating it with ovals.
The replacement part showed up today. This time I enlarged the #40 pilot holes in the part, and then drilled #40 holes into hard maple, in order to provide a hole that would prevent the bit from walking. What a difference!
Stopped for the evening after counter-sinking, deburring, cleaning, painting, dimpling.
Total Time: 1 hour
