The Missing Measurment

[Rob]

On a D-18 Martin close to 1964 should someone own one in millimeters can you tell me the exact measurment on high -E from center slot to center of pin hole ad low -E center slot to middle of pin hole. Want to make sure its right before I drill holes. Should the holes be 100% square with front of bridge as myGuild is not? Thanks -nanccinut

The line holes is parallel with the front of the bridge. As to the saddle location, I always leave that until the bridge is glued in place. Then I can measure the saddle placement precisely in reference to the nut and frets, and rout it in the correct location.
