The Holiday's are past us, and the long weekend of total relaxation allowed for a nice break from the project...time to get back to work though! Picking up where I left off with the screw plates...I drilled, primed, and riveted those to the gap plates.
Then I put everything back on up front, and torque'd the prop bolts down to the proper 42 ft-lbs. This made a slight difference in the alignment of the pilot holes I drilled, but that's why I drilled them #40 to start! I also put a laser on the tip of the spinner, aligned with a mark I made in the center of the tip. This is a MUCH better way to check the spinner for true center rotation over the 'pencil clamped to a ladder' method.
A Navajo's wingtip lended itself nicely for the laser to rest on, and made for easy changes in getting it centered on the dot.
With the spinner reconfirmed that it is in fact centered, I stepped the holes up to #30, then rechecked the laser to the center dot...all looks good!
And finally tonight, I drilled the screw holes for the screw plates, and then stepped all the holes up to #19 for the #8 screws that will eventually be used to hold the spinner in place...after I put damned nut plates everywhere...
