I used the router table to smooth away the divots from drilling out the head slots.

Final smoothing will be done after tuning machine holes are drilled.  To ensure the holes are spaced properly, and equally balanced from side to side, I built a jig to direct the drill, locate the trio of holes, and prevent tearout upon exiting the headstock into the slot.

It’s a bit crumbly, as part of it is MDF.  I may rebuild with birch ply if I need to use it again sometime in the future.

Using the jig, I was able to drill holes, avoid major tearout, and dry fit the tuners to check appearance.  The top drums will need to be trimmed as they bang into each other due to the narrow profile on top..
