After we sent our 850-hour prop to East Coast Propeller Service in Lititz, PA for resealing and repainting, we felt a great sense of accomplishment lifting it into place and carefully engaging each of the special hex bolts into the engine prop flange. Carefully torquing each bolt and then safetying wiring them finished the job. But what a pain getting the .041 safety wire around the nuts in such tight spaces.
Installing the propeller was made far easier because we purchased an Ultimate Prop Wrench from www.antisplataero.com. If you are not familiar with this slick tool, do take a look at Allan Nemmo's web site. He's primarily focused on tools for RV builders, but many of his creations are useful to any builder.
