I decided it was time to reinstall the propeller so that I could finalize the cowl installation. This when pretty smoothly with the engine hoist. Now that the spinner is almost done, I decided to took a few hours to finish the gap fillers. I added fiberglass taps to these pieces using 6 layers of glass to secure them to the spinner. I rivetted nutplates on the tabs for the securing screws. Final assembly was nice and tight.
