Tuesday’s session was very productive. In the picture below, the two pieces on the top (F-01405J - Angles) and the two pieces on the bottom (F-01405H - Shims) had the holes deburred and edges cleaned. The holes in the Shims were also countersunk.
These are the two F-01405K - Guides. These two pieces also had the edges cleaned and the holes beburred and dimpled.
Below is the left F-01457 Gusset (the right gets prepared the same way). To start, the Gusset gets clecoed to the Upper Longeron with the #40 hole and is “rotated” until it overlaps the outboard edge of the Side Skin. Once it is in the correct place, it gets clamped to the Upper Longeron and the eight holes (where the clecos are installed) were Final-Drilled to #30 and the two bigger holes (by the blue clamp) were Final-Drilled to 1/4”. Again, this is the left Gusset.....
.....and here is the right Gusset.
The last step in preparation of the Gussets, is to countersink the 10 holes as shown in the plans excerpt.
Here are the two competed Gussets.
