I did a best fit to get the cowling in a close to the right position. There is still some overhang on all the edges, so the bottom section doesn’t fit up even with the skin yet, but I want to see how much I need to trim off to get it to fit up close to the spinner. I think if I had just trimmed to the scribe lines then the contour up to the spinner would lean a little to the left (fwd looking aft). This way I was able to center top cowling around the spinner. Next, I will mark the edges that need to be trimmed and try to sneak up on the right amount of material to remove.
cowling close to position, but still has overlaps to trim off
spinner gap close, but could be a little closer
now to mark the edges and sneak up on the amount needed to trim
