But first we have to get the butt block made and glued on.

The butt block is a light piece of Honduran Mahogany that I had cut from scraps left over from band sawing necks. I had a number of them all cut to the proper length and width and ready for their final shaping. They are taken to the sander and gently rounded to fit the curve at the bottom of the instrument, and here I am sanding off some excess wood to save a little weight, leaving enough of a flat surface to mount a pickup.
This ought to fit the curve nicely. Remember to set it back from the line to leave room for the sides that will be glued to it.
Here they are, glued and clamped. Now one more thing !
I like to put this thin maple veneer patch around the sound hole to prevent the possibility of a split of the Cedar soundboard. The maple grain runs crossways. Just a little insurance. When the glue dries we can put on the sides.
