Print this drill guide FULL SIZE on 8 1/2" X 14" paper. Measure the board length of the printout to verify it is 13 1/4". Attach to blank board using double sided carpet tape. Use a center punch to put a mark at the cross hairs of each turret, standoff, and hole. Use a 3/32" drill bit to drill all holes. Then enlarge holes as needed for standoffs and wire pass <<< Use a highlighter to mark jumpers as they are installed.
