Drilling the Arcades
Now, chuck a 3/8” [9.5mm] forstner bit into the drill press. Do Not Move The Fence! You want to drill this series of holes
1/16” [1.5mm] deeper than the first series. Use the test holes you already drilled into the waste area to get the depth stop setting correct.
When satisfied with your setup, drill another 30 holes in the center of the holes you already drilled. The bit will find the center
hole from the first drilling and guide itself.
This is what your blank should look like after this series of holes.
