DLP Mandolin - 11 - Drilling Holes for the Machine Heads

Last night't task was to drill the 8 holes for the machine heads.  after some careful laying out I marked up the 4 holes each side taking into account the length of the all in one plate on the back of the head.


Now this is where my new drill press really comes into it's own.  I put a sacrificial piece of scrap underneath the head so the bit didn't rip through the back of the head.  I used a 'lip and spur' drill bit to minimise tearing on the face of the head although there is a ferrule to tap in which would hide minimal tearing.


I still have to drill a step into the top of each hole to accommodate the ferrules but that can wait until tomorrow.
