Battery Cable Routing - Tail Cone to Firewall

Image
While planning out routing of conduits under the baggage area rear seat floors, I also took time to plan out battery cable routing.  My electrical system will consist of a single battery, single alternator and backup generator setup, and the battery will be placed in the standard location in the tail cone. I have also decided to ground the battery at the tail cone, and this means that I only need to run a single 2AWG battery cable from the tail cone to the firewall. I purchased a 15ft length of 2AWG tefzel cable with a red colored casing to easily identify it as the positive power wire, and carefully planned out where I would need to attach brackets to support the cable as it gets routed down the left side of the airplane.  The cable run under the baggage area requires the most supporting brackets as this is a relatively long run, and aside from making sure that the cable would be secure, I also wanted to keep it as far away from the conduit runs as possible. From the tail con...

37 - Fuel System - Configuring systems brackets and fuel selector

For the fuel (and brake) system hoses I am using those made by Aircraft Specialty in order to avoid having to make my own from the Aluminum tubing that is provided in the kit. As I get a better understanding of which hoses run where, there a three that need to run under the front seat on each side of the airplane two -6 hoses for the fuel system, one out and one return one -4 hose for the brake system The systems brackets that were previously riveted to the bottom skin are used to route these hoses under the seats, and the plans have you install rubber grommets and aluminum braces to lock everything in place. As the Aircraft Specialty hoses have a larger diameter than the aluminum tubing (for which I had previously enlarged the guide openings in the systems brackets to accommodate those hoses), I decided to use a 3D printed bracket (once again designed and made available by Allan Glen) that screws into the systems brackets into which the hoses clip perfectly and can be secured with zi...

38 - Rudder Pedals and Brake System 38-4-3 to 38-4-4

Image
I made a start on rudder pedal installation while there is still easy access to the forward cabin area. I had previously documented assembling my Control Approach rudder pedal kit, so pulled those out of storage and jumped ahead to section 38. Skipping over the instructions that have you assemble the Van's stock rudder pedals, I started by drilling the Delrin support blocks that will hold the rudder pedals on each side of the cabin. Using the bearing block mount plate as a guide, I drilled #12 holes into each bearing block about 1/8" deep (it doesn't take much drill pressure to drill into the Delrin!), and then moved to the drill press to finish drilling the holes all the way through to #10. Drilling the bearing block on the drill press. I made sure the drill bit was perpendicular to the block prior to drilling, and first drilled each hole to #12, and then reamed to #10 Left bearing block holes came out perfectly matched with the mount plate holes. Right bearing block requ...
