Bernie holding the canopy assembly open while I
marked the area of interference with a Sharpie pen.
Unfortunately, I forgot to take a photo of the finished shape of the canopy arms so will need to edit this post later and post a photo of the final shape.
Now that the canopy is fitted, it will be set aside so there will be easier access for installing the instruments and wiring along with modifying each of the three panel sections. Not having the canopy fairing totally fitted has been holding me up some because all three of the panel sections will require some cutting … however, it has been necessary to keep the instrument panel sections screwed in place to hold the shape of the upper forward fuselage skin.
The plan is to add two rocker switches to the DOG Aviation RV-12 … one to control the electric fuel pump and the other to control the additional left landing light. I have opted to keep the left landing light switched so as to not overtax the electrical system. The wig- wag function will be controlled by the pulse switch already a part of the RV-12’s electrical wiring and this requires no additional power to operate the left light because only one landing light is illuminated at a time during wig-wag operation. However, do not want the left landing light to go steady on along with the right landing light, so it is being wired to a separate switch … should I need the landing light for a night landing, it can be turned on during short final, then off again when back on terra firma.
My original thought was to place the fuel switch above the AV-50002 ignition & start module and the left landing light switch in the glove box panel to the right of the existing switches in the center panel. However, upon review of “the look” … the left landing light switch would be an orphaned switch because of the spacing necessary to clear the mounting bracket for the panels. So have decided to install it above the ignition module adjacent to the fuel pump switch. A paper cutout was made utilizing the same switch spacing as the ignition A&B switches and there is just enough room for the two additional switches to be placed directly above the ignition switches. This should give the instillation a cohesive look and also provide sufficient room for switch labeling.

switches spaced the same and directly above the two ignition switches.
The paper cutout my finger is pointing towards represents
the total space taken up by the existing two ignition switches including separation
and bezels. As can be seen in the photo, there is enough room to place the two
additional switches inline and directly above the ignition switches … this mounting
location should create a cohesive look.While having the F-00060 left instrument panel in hand decided to go ahead and countersink the #40 rivet holes for the nutplates and the F-00061 stiffener. Van’s calls for countersinking ALL of the panel’s mounting holes for flush #6 screws … however, I’m opting to change the look a bit and will either go with stainless Allen cap head screws or Torx pan head screws.

The plan is to get the instrument panel pieces powder coated so decided to have all the rivets in place prior to powder coating. The six nutplates and F-00061 stiffener were riveted onto the F-00060 left panel.

All that is left to do to the F-00060 panel is finalize the position of the additional switches and cut the two holes for the additional switches and it will be ready for powder coating.
