[3 hrs] Today I drilled and cut material off of the engine pylon front support piece (814-3).

Damage to the original piece can be seen on the bottom right of this photo. I made the top hole (on the right) slightly smaller to keep a bit more structure in the area.

Notice that the outer perimeter of the second hole from the right looks different? I had to clean up some scratches that resulted when one blade on the double-bladed fly cutter came lose and moved out on the shaft. Doh!

Here is a view of the underside…

[1.5 hrs] After months and months of Coot building inactivity, I finally actually drilled, sawed, and filed today.

The part is the 814-8 pylon doubler. This piece attaches to station 96, and doubles the forward vertical pylon support. The piece that I have from the partial project I purchased is not airworthy—it has a fracture owning to (1) the plane rolling in a road accident (while being trailered) and (2) lack of a stress relief hole at a critical point. You can see the fracture in the large image (click on the photo).

Here is a view from the back-side.

Oh…my new part really is relatively symmetrical. The photo is deceiving because the camera is centered between the old and new parts.

I just upgraded the blog to WordPress 2.5, so drop me a line if anything seems broken.

While you are waiting for another construction-related post, here is a youtube video of me flying my AA-1 Yankee last summer:
