Forward Cowling Seals Done...What a PIA!
I spent a ridiculous amount of time getting the forward cowling seals right. Embarrassingly so. Mechanically they are quite simple. But the cowling as initially fitted was not going to work correctly. I had no choice if I wanted them to fit right. My efforts paid off and after getting them drilled, countersunk, and test installed I did a fit check on the plane. For the most part the seals fit nice and flush on the air ramps with just a couple of small bumps. I think with heat and time the bumps, which are small now, will go away. I had the lower cowling on and off a couple times prior to drilling to check spacing and clearances. Using a file, I chamfered and thinned the lower intakes edges, particularly in the corners where there was interference. I also using my rotary tool to grind away excess cured flox that was unneeded and now was just excess weight. It's good to have that done and I can finally move on to something new.
