Attaching the PVC Pipe to the Soundboard

A centerline was drawn down the back of the soundboard, and four evenly-spaced 1/8" pilot holes were drilled along this line. Placing the PVC pipe string side down, the body was clamped on top of the pipe along the centerline with the tuner side of the pipe facing away from the body. Four lag bolts were drilled in the four holes of the body and into the PVC pipe to attach the pipe to the wooden soundboard.
