I used the hole finder to drill the last two holes in each side of the canopy skirt – they're the two silver clecoes in the middle of this photo. Also notice how the fiberglass skirt here on the right side of the airplane is slightly too long to match up to the edge of the C-660 side skirt.
On the left side, the skirt is slightly too short. Something must have gotten misaligned pretty early on. But it's no matter – I just cut a slight (1/8") taper on the rear corner of the left side skirt, and sanded the fiberglass skirt to match. Then I cut the same taper on the right side skirt and trimmed and sanded the fiberglass to match over there too. (Heaven forbid I shoud have an asymmetrical canopy!) It looks nice now, even though I seem to have forgotten to take a picture.
On the left side skirt, I trimmed an inch off the upper rear corner, where the bottom-most rivet hole in the plexiglass had way not enough edge distance on the aluminum skirt. This will all be covered with the fiberglass skirt once it's all put together.
Once the bottom edge of the aft skirt was finalized, I sanded a nice round profile on the protruding front corners, using a quarter to gauge the radius. (I used a Kentucky state quarter, but I think you could use any of the southern states with good results.)
