Brief Description:  1 - Installed spinner

I was away from the shop for a few days for travel to DC (personal and business), followed by a routine medical procedure. That is why I was determined to knock this job out in one day. Mission accomplished! I started by drilling out the 2" openings with a brand new hole saw to get the best result. No challenge at all. Then I extended the lines to the back edge and cut out the back of the two circles for later installation. I chose to temporarily reinstall the prop in the hub so I could easily turn over the engine to check the runout on my spinner. Oh, before that I marked the locations of all holes that were to be drilled so I wouild be ready once the spinner was aligned properly. Using a laser level aimed at the tip, I was able to confirm that it was as perfectly aligned as I could do without a purpose-built jig. I then clamped everything in place and drilled #40 holes. Because of the potential for chewing up the fiberglass while drilling through to the metal, I elected to drill the bulkheads and spinner separately. I step drilled up to #20. Next I drilled the bulkheads with a #19 to allow the 8-32 machine screws to fit through for aligning the nutplates. Using that method, I temporarily screwed into each nutplate and drilled the two mounting holes while it was secured. Then I countersunk the mounting holes in the bulkheads to allow for flush mounting with countersunk rivets. In a last minute change, I drilled the nutplate holes in the fiberglass bulkhead to #30, along with the actual holes through each nutplate. This allowed me to secure them with A4 rivets, which were much easier to install in the softer fiberglass. On the rear bulkhead, I solid riveted everything. The hardware that I used came with the spinner from Van's and included machine screws AN509-8R8, nutplates K1000-08 and Tinnerman #8 washers A3135-01 / 0-24A. The ultimate test will be when I fire up the engine the next time. I'll be anxious to see how close I got my spinner alignment to the ideal.
