After finishing trimming I was checking the movement of the elevators to ensure a smooth and full swing when I found a problem. Earlier when I was building the horizontal stabilizer (HS) the plans had me cut out a small section of the HS aft spar to allow clearance for the elevator horns. Well the right horn was fine, but the left was about 3/64 too long. You can see the small amount interferring in Image 2. So, I trimmed the HS to allow the complete movenment of the horn. I finished up the day by torquing the attaching bolts for the counter wieghts. Next is fiberglassing the tail tips.
