Since I am now a seasoned pro at Dzus fastener installation, I invited two other sets of builders (Yeol, Chad, Sasha, and Peter) to put the Dzus fasteners in their seats. I now have a total of 9 fasteners under my belt for either installing or supervising, so I may even be a guru! Actually, it is really easy with the right tools. Both sets of builders got their seat backs done, I installed the springs for the other half of the Dzus fasteners into the back floor of my plane, and we spent a lot of time talking about the build - what to do next, things to watch out for, etc. Side note - when riveting the springs into the floor, I used the countersunk rivets Sling provided, I countersunk the floor for them, and I used rivet backers on the rivets to make sure that the rivet didn't pull through the spring at some point.
