Cowl Fiberglass Fixes (5)

 5 hours

The cowl was pretty much installed but I still had some areas to work on.  First, I sanded down and filled in the holes I had drilled through the prop hub area when I initially fit the cowl.  While working in that area I also found a bunch of little voids in the surface of the fiberglass that I also cleaned up and filled in.






Next I installed the side scoops.  I wanted a convenient battery charge port, so I figured a good spot would be in the top of the left scoop.  It's easy to reach but you can't see it unless you're looking for it!  I attached the scoops to the cowl with some epoxy and aluminum rivets.  I added a little bondo to smooth over the edges where it met the cowl too.






Here's the battery charge port in use:


Next was the exhaust exit.  I just did my best to line up a spot on the inside of the cowl that would match the exhaust pipe and drilled a 3" hole with a hole saw.  It lined up close enough!  Then I adjusted the wrap on the pipe so it didn't hang out the bottom of the cowl.




The last thing was a hole for the coolant and oil vent tubes to go through.  I marked a spot where the vents ended up and cut about a 1"x2" opening.  I think with that done, the lower cowl is done!
