Title: Cowl seams; Inlet ramp
Continued working on cowl: 1. Sanded down the hardened epoxy strips on the inside of the top cowl, and also the filler on the inlet edges. Mounted the top cowl. The fit looks pretty good along most of the seams! More interestingly, the epoxy strips did a great job in bringing the cowl level up to the skin level. I might even have to sand them down a bit more. 2. Marked the cowl edges for some areas that I will bevel with a file to improve the transitions/seams. 3. Removed the top cowl and beveled the marked areas. Inlet ramps: 4. Taped the left and right inlet ramps in position in the top cowl. Marked them for trimming. 5. Trimmed the ramps, rounded the edges, and roughened the contact points with 80-grit sandpaper. 6. Drilled and clecoed the ramps into position. 7. Sanded the inside of the cowl underneath where the ramps will go. Roughened the contact points. Cleaned up everything and removed all Sharpie marks. 8. Mixed up some resin/flox and bonded the ramps to the cowl. Re-inserted the clecoes to hold them in place while the epoxy cures. Inlet seams: 9. Added some cabosil to the mix to prevent sagging, then used this mixture to add a small bead along the right inlet ramp junction. 10. Taped along the desired seam lines of the propeller hole in the lower cowl. Added more beads of the thick epoxy mixture along this tape edge. Let it set for 15 minutes or so, then, pulled off the tape. Scraped off as much extra epoxy as I could, Tomorrow I'll carefully sand the seam line, and see how much of an improvement it makes.
