for centering… i placed the blank on the machine, before i glued the maple top on, and engraved a small section of center line at the top and bottom edges. If you notice the tiny notch cut out at the bottom of the maple, it is to allow me to see the line.Then I used that center line as a reference for gluing up the top. not as hard on my body, as it is a one-piece blank. On the one i’m about to cut, i measured to the glue seam in the two-piece blank with a metric ruler, then centered the design off that x-axis point.
and Yes, my strat pocket is a 56mm (2 3/16") standard strat pocket
