Once I got all the studs inserted, I used the prop extension wrench to slowing tightened the studs down, 2-3 flats at a time, working through the pattern. After the studs were fully down, per the manual, I torqued them to 40 ft/lbs and then to 65 ft/lbs. Once the prop was on, I attached the hub and gap fillers to verify clearance. I clamped a 2X4 to a blade and using that as a handle, twisted the blades from stop to stop check for interference. The cutouts and gap filers all needed a little work, but it didn’t take long to get adequate clearance all the way around the blades through their full range of motion. I then riveted the gap fillers on to the spinner backplate. That was more involved than I had planned and required me to release the backplate from the hub so that I could get access to a couple of the rivets.
