System and method for forming aligned holes in a work piece

A drill jig comprising:

• an edge alignment guide configured to abut an edge of a workpiece to facilitate movement of said workpiece along a first straight line;
• a hole-spacing assembly including a protrusion and a first biasing member engaging feature, said protrusion disposed to engage a preexisting hole in a workpiece positioned by said edge alignment guide;
• a second guide coupled to said hole-spacing assembly and configured to facilitate movement of said hole-spacing assembly along a second straight line perpendicular to said first straight line, whereby said protrusion can move into and out of said preexisting hole;
• a first biasing member coupled to said hole-spacing assembly and operative to exert a force on said hole-spacing assembly in a direction parallel to said second straight line;
• and
• an actuator including a second biasing member engaging feature, said actuator being responsive to a force applied by a component of a drill and operative to move said hole-spacing assembly along said second straight line via said first biasing member;
• and wherein
• said first biasing member engaging feature and said second biasing member engaging feature remain coupled to said biasing member when said biasing member is under tension.
