Some ups and downs in my recent work on the airplane. I am
excited about how the oil door has come together, but also made a mistake
(recoverable) on the cowling.. So we’ll
talk about the oil door first. I got a “hidden”
hinge on a previous order and was excited to finally be able to use it. First I gut the square hole in the cowling
just over ½ inch inside the edges of the indent for the oil door. I rounded the edges and it looks pretty
good. Then I started drilling the two
pieces of the hidden hinge. I put a
piece of .040 under the piece of hinge that attaches to the cowling to help
offset the door so that it was flush when closed. Also, the way I placed the hinge, it heat the
upper section of my cowl cut out when I first functioned it. Took off about 1/16 inch additional and am
really happy how it finally turned out.
I have some “Hartwell” trigger lock flush latches on order that will be
installed this week, to finish the door, apart from the riveting. Also, I would not be nervous about making
the door smaller than the “frame” on the cowling. I have a good 1/8 inch outside of the door to
the frame, which is good as it ensures a flush fit. The additional space will be filled in later
as I finish the cowling, to frame the door in nice and tight.
Onto the cowling. I
am happy the way it turned out, but after the fact realized I used the wrong
hinges to secure the upper and lower cowl.
I used the hinge that was intended for the gear leg fairings. It’s a very slightly smaller hinge and I
assumed it looked good for the job.
Also, the hinge I was supposed to use I had previously used somewhere
along the line, probably for the seat
backs, so I will need to order more.
The fix will be easy, just bummed due to the time involved. But that said, the cowling now completely
supports itself and I am really happy with the tightness and flush-ness of the
install. Hopefully when I replace the
forward hinges I will be able to keep it the same.
Also, this weekend we had good weather for the first time since I could remember, so I pulled the plane out and let her see the sun for a while..
