Clamped, drilled, cleco'd, and riveted the nylon upper elevator stop.
Fished the left rudder cable back thru the fuselage. Initial time I installed it the elevator cables got wrapped around it so I had to push it thru the fuselage hole to re-run.
Once the rudder cable was properly installed, I noticed that the elevator cables were twisted together. Twice. Fortunately didn't have to fish these out. Just disconnected at the bellcrank and un twisted.
I got to thinking about it after riveting the upper elevator stop in place, so I added a small section of aluminum skin under it. Riveted in place.
Zenith suggested "stretching" the upper fin L angle to get it to match the curve of the upper horizontal stab. They suggested using a hammer to stretch it using a vise for support. Not thrilled with the result; I may end up notching it and bending that way. We'll see.
Lasting, reinstalled the horizontal stabilizer added side gussets in preparation for final riveting/bolting.
