Spent a relaxed Sunday afternoon trimming up the two ukes and cutting the binding recesses. Also put the four marker dots on the Baritone fretboard. Here is how it is done after some careful measuring and marking with a pencil.
With this sharp awl, make an indentation exactly where you want the dot to be centered, That indent will guide the drill bit and prevent it straying.
with this finger drill, make a small beginning hole at the Awl mark, just enough to guide the large drill bit that follows.
Now with the old fashioned hand drill fitted with a 3/16th bitt, start the final hole, But go slow, you don't want it very deep.
Now all the holes are started. It is time to measure for depth.
Measure the thickness of the Paua Abalone dot. That is the depth of the hole you want to drill.
that thickness will be expressed by the little protrusion at the bottom of your micrometer. It will guide you as you drill a little deeper, test for depth and then drill again.
When the holes are just right, drop a little glue in each hole and pop in the shell dots. Push them down tight and your job is done. Don't worry about the glue on the wood. It will be sanded off when you sand in the radius.
