1. Reviewed the fit of the aft six baffle pieces. They seem to be in good shape, so I moved on the front four baffles. 2. Installed the side baffles at cylinders 1 & 2. Placed paperclips side by side on the tops of the baffles, then placed the top cowl down on them. 3. Removed the cowl and checked the clips. Made pen marks, trimmed off a bit of the baffles in the locations needed, then installed the baffles and cowl again. I repeated the process at least 7 times to get a consistent 3/8" gap all the way around. 4. Once the side pieces looked good, I moved onto the two front pieces -- the ones that seal around the front of the engine. I clecoed these pieces in place, then added the paperclips to the top edge (although it's pretty easy to just look inside the cowl inlets to see your progress with these). I installed and removed the cowl, baffles, and paperclips about 10 times as I worked to get these front baffles trimmed correctly. 5. Marked the cowl inlet edges for final trimming. I truly had no idea how many DOZENS of hours it would take to get the baffles cut and fitted. I took a ceremonial picture of the cowl laying down completely, with all the baffles in place. It's a big event!
