Like many before, I'm unsure about how to get my upper cowling and lower cowling to fit each other around the spinner.
Vans indicates that the spinner area should be fit so that the spinner opening is circular, then drill holes at point "B" (shown in picture below). However, the front of the already-fitted upper cowl currently overlaps the uncut lower cowl the at the outboard locations (points "C"), preventing the top cowl from sitting down on the bottom cowl at points "A" or "B". This suggests that I'm going to have to first trim down the cowl at points "C". However, how do I how much to trim here until the top and bottom cowls are on the fuselage at the same time? I definitely don't want to do this until I know how much needs be cut off. It seems like a chicken-egg scenario.
Any suggestions on how to proceed would be much appreciated.
