Since I’m following the plans and riveting the Side Skins from top to bottom (and back to front—my decision), I decided to go ahead and install the nutplates into their appropriate locations as I move along. There are two types of nutplates installed in this section. The first are K1100-06 (center pre-dimpled) used to go over a hole that has been previously dimpled. The second is the K1000-06 (not pre-dimpled) to go on a flat surface such as on a Longeron. However, either of these nutplates can have their attach holes dimpled for different applications.
In the picture below, there are six nutplates (K1100-06) riveted into place that will attach the Access Panel Covers. Each screw hole will use a #6 screw and hold the cover plate. There will also be two additional nutplates installed where the orange tape is located.
The plans call for the installation of round head screws on this Access Panel Cover, but do provide the option for flush head screws. There are a couple modifications (provided in the plans) that need to be completed for these screws. For various reasons, I have decided to use flush head screws on this Panel. If you choose the flush head screw option, you will have to order extra K1100-06 nutplates. I ordered mine from Van’s.
This is the opposite side of the same access panel showing the K1100-06 nutplates riveted into place with the shop head side of the rivet. You can also see the two locations (with the orange tape) that will accept the last two nutplates.
The picture below shows three of the K1000-06 nutplates installed on the inside of the Left Longeron. These nutplates will ultimately be used to attach the Empennage Fairing.
There are still TONS of rivets to be installed in the Side Skins! So, more to follow......
