Though not in chronological order: 1/64th ply "cheek" pieces added to the aft fuselage with balsa added to the inside edges to reinforce everything. Also, the rudder horn is hidden under a piece of 1/64th ply and the clevis permanently
mounted as well. The photo with the X-Acto blade highlights the trailing edge of the stab trailing edge where it meets the fuselage. Two pieces of 1/64th ply were cemented together and was the ideal width to mate with that area after which the outline was sanded in place.
At this point, the balsa fairing pieces needed to be lengthened and this was subsequently done using House Bondo where the black lines indicate. The next group of photos will show the finished product when posted at the next installment.
