Putting it all together, and then one last detail: do not attempt to do this free hand! Get both 15/16 and a 1-inch forstner Bits. First step: Use a drill press and drill approx 1/4 inch deep with the 1-inch bit. (Just a hint less than the height of the insert). Second step: Then swap to the 15/16 and using the same pilot hole left by the first bit, finish the cut through the surface. Note: Always use a drill press! Third step: Then use epoxy glue to glue the inserts in. Final step: Let dry and then you’ll be sanding the whole surface down to be perfectly smooth.
