Brief Description: Finished up control tubes and started main power
I finished up the control tubes this morning and clocked them all to the starting position for install. Why are they painted gold? I had it laying around, matches the alodine, looks good, pick one. One of the things I have been thinking about quite a bit is where to run the two #2 welding cables that make up the primary battery runs to the firewall. Many people are using the airframe for the ground to save the weight and hassel but that can cause corrosion between joints and cause multipe groud paths. But more importantly I wanted to make sure I had full power available from the battery for starts in the cold WI winters. Most people are running the cable up and around the sides but I am not keen on the idea of running high current lines past all of the comm and other antenna lines. The best solution I could come up with is to run them straight up the tunnel with one on each side. Once I get past the fuel valve I will bring them up along the inside and out the firewall. " You are running main battery cables past the fuel lines!?!" you say. Welcome to aviation. Not a lot of room for stuff in the airframe and I would need a combination of a fuel leak, which in the enclosed cabin I would smell immediately, and a chaffed positive cable rubbing against part of the airframe in order to cause a problem. As long as the cables are secured so they cant move you pretty much eliminate any chance of a short. And welding cables are made for abuse.
