-The rear trunnion needs to be drilled and tapped using a #21(.159)drill and 10-32 tap(gun point tap preferred) -The holes are .625 center to center -The position of the hole pattern is centered vertically and horizontally on the rear trunnion. -Once the hole locations are marked use a center punch to indent the holes -Use a spot or center drill to make divots which help keep the #21 drill on location -Drill the holes with a #21 drill, some people start with a smaller drill and then follow with the #21 -Tap the holes with the 10-32 tap, a high quality tap makes a big difference in the operation, we use Cleveland but there are lots of good brands. -Use go slow and use cutting oil on all drill and tap operations. |
