Milled a relief slot for the Tosen control stick wire bundle exit. Started with a 1/4" slot, but trial fit of wiring bundle was too difficult so a 3/8" slot was milled. Drilled #21 holes to be tapped for #10-32 screw to hold the control stick in the adapter. Chamfered the edges of the slot to break the sharp edges. Fit the adapter 1/8" from the bottom of SNB-C04-07 control stick fitting to allow for misalignment. Marked previously drilled taper pin locations. On mill, drilled adapter through the diameter with a 1/4" hole (small end of #2 taper pin). Inserted adapter in control stick fitting and used a #1 S&J taper reamer to cut adapter. The #1 taper requires using the far heal of the reamer to cut enough taper for a #2 pin. The taper in the adapter provided a good taper pin fit at the stick adapter. Finished the adapter by using a rat tail file to put a slot in the control stick adapter to remove any sharp edge in contact with the control stick wire bundle.
Tapped 2 - #10-32 threads in the upper part of the stick adapter in the recessed steel control stick frame(needs photo).
