Used #1 reamer to cut tapered hole for #2-12 taper pin fitting single control stick tube SNB-C04-03 to control stick fitting SNB-C04-07. The #1 taper is just able to cut enough taper for the #2 pin. Used Boelube solid as a cutting lubricant.
Drilled the aft end of the control stick fitting for push-to-talk wiring. Cut fore and aft slots in stick to match hole in fitting.
