Brief Description: Reassemble elevator & rivet bottom side
1. Reassembled the elevator, with a cleco at ~ every 3rd rivet hole.
2. The pneumatic-hydraulic riveter was not working well--it required 4 or 5 trigger pulls to pull a rivet. I disassembled the riveter and reassembled. It still required several pulls. Then I recalled a post to the Matronics Zenith Forum that said HF riveters required some fine tunning adjustment to work their best. So, I tried reducing the length of the jaw assemble to ~1/16" < the gauge length on the spanner wrench. That made a tremendous difference. With that small change, the riveter would consistently pull the rivet with two pulls.
3. I pulled the rivets in the 2/3's of the holes that did not have clecos.
