Met my weekly goal for another week. Located the two contactors on the firewall and temporarily secured them with tape. Clecoed the bulkhead fuel feedthrough doubler in place. It was close but seemed like it might work. Looked at all of the drawings I received with the FWF documentation packs to see if there was any new information about firewall items. Decided the VA-136 fuel line from the bulkhead fitting to the engine driven pump was a problem since it turned toward towards the solenoids. Decided to ask some other builders about their experience. Used the COM doubler paper template and started fabricating one out of 0.030" thick 2024. The angles lined up on the first try! Now I need to trim and bend up one of the edges and drill mounting holes. Fabricated a doubler for the transponder that would nest between two seat ribs. Made it too large to fit. Made two more blanks so I can try again later. Drilled the top hole for the VA-168 transducer manifold and the match drilled the second hole. Started drafting an email to builder friends about the potential interference issue with the contactors and fuel bulkhead and hose assembly. Took screenshots of photos and parts of drawings to help explain the issue. After looking at my engine mount and some of the assembly drawings I realized the VA-136 fuel line for tricycle gears was added to route around the new (in 2019) elastomer nose gear mount. My nose gear is the older style and uses the same hose as the taildragger version. So I plan to install contactor nut plates and doubler per the drawing and install the contactors as far up and towards the copilot side as possible. Then I will see how much clearance I have and will adjust the fuel fitting double a small amount if needed. I purchased two small enclosures for the flyLEDs controller board. After looking for a mounting location, I decided I would mount the bare board under the pilot seat. I cut a piece of aluminum sheet to size and marked the PCB mounting holes on it. I'll use the aluminum as a drill template and I plan to use 1/4" aluminum standoffs with 4-40 threads.
