11 March 06 - Baggage Floor, Wiring the Clock


A few projects, today: a big goal is to get the other baggage floor in, which is fairly straightforward, however, there are some odds and ends that need to be finished before that gets put in place - making sure everything is deburred, making sure the PVC conduit is attached well in the front, etc. Nothing major. After you're actually pulling rivets, it's all downhill. This ends up being my job as it involves being crammed into somewhat uncomfortable positions inside the plane.

In other news, dad's still working on the electrical system. Today he's working on the clock - this is a Falcon product, but we bought it from Van's - that has sort of weird milspec connector for the wires. This connector has been driving him bananas since he started playing with it, but it's all together now, though, and seems to work, although not quite as advertised. Installation error, maybe? We'll see.

Pop rivets for the baggage floors have been pulled. The next project with this is to get all the nutplates in the center and the back. There are some additional rivets in the back part that can be squeezed. Then we'll get the side panels in.

Here's the clock, all powered up. It can do flight time, elapsed time, and has bright and dim settings for day and night. Unfortunately, flight time and elapsed time do not both run at the same time, which is sort of a problem.

There's the aforementioned connector for the clock, soldered, heat-shrunk, and tie-wrapped.

What's with this clock? Well, it's pretty cool, despite not doing what we thought it was going to do. The idea here is that the switch right next to it momentarily contacts one of the wires to ground, which resets flight time - the total time - sort of like what you would expect when you turn the airplane off. However, flight time only elapses when that switch is held down, which is not good. It's just supposed to be a reset, so it's a momentary switch that you have to hold in that position.

Reseting the elapsed time (use it as a fuel tank timer, or something) is easy - just click on the zero switch on the clock. In any case, this will have to be rethought. When this clock came, there were two wiring diagrams that were presented as options, and we just picked the one that we thought would make the most sense. Maybe we guessed wrong. We'll try this again tomorrow, and I'll remember to snap a few pictures of the wiring diagram so this will all make more sense to you guys out there.
