So, I'm still on step one.
I have been assessing the six horizontal tail bushing locations for alignment. Just sticking the reamer into each as far as it will go without cutting, I find one lug to be larger than the reamer (reamer freely/easily passes thru) and one seems to be slightly off parallel. I have held off reaming these 6 locations thinking I should attach a rod to the reamer to help insure the finished holes are parallel to the stab and in-line. I want to avoid either slop or binding of this attachment.
What are others experiences on this step? Am I over working this?
