Brief Description: Spinner build up inside and alignment check. Prop
During the last session where I had checked the spinner for center alignment, I had adjusted it by tapping it as I turned the prop not realizing that it worked forward a small amount and a loss of tight fit on the fwd bulk plate. I realized this when I screwed the front plate in checking for fit. Dang! Soooo, The spinner being off center isnt good and the crush plate not seated firmly isnt either. I cut some narrow strips of 9 oz glass and laid them end to end on the inside circumfrence where the fwd plate resides and applied the epoxy. Today I sanded the area smooth trying to keep it even. When I pushed the spinner on to the drilled screw holes, I coulod feel good pressure indicating that the gap must be filled.
Installed 11 of the 20 screws with nylon washers. I dont have enough to do all so I will need to order some. Had trouble with 2 screws not wanting to go in straight so I ran a tap thru half way and that did the trick.
Set up a drill bit to point at spinner center again and rotated prop thru 360 degrees. Guess what? I got slight wobble! About 3/16" thru 180 degrees, slightly less thru 90. I marked the position for each 90 degrees. Im not real sure if I have wobble or if I just didnt have center marked on the spinner correctly to begin with. I think Ill leave alone and have someone video it during engine run to see for myself.
While I was checking this I decided to check that the prop is still tracking true now that I have torqued the prop bolts down. I traced a line on either side of the prop edge when prop was vertical and then rotated it carefully 180 degrees. The other blade lined up perfect inside the 2 lines. No worries there!
