Cable guides will be needed on the aft side of the spar bulkhead. I decided to make these parts now as a break from the other fuselage work. These parts are not really depicted in detail on the drawings, so there was some poetic license involved. I figure the lateral load is small (about 20lbs). The cable guide post was riveted in place and allowed for a cable angle change of about 10 degrees aft of the bulkhead.
