I decided to redo my fuel tanks. See here for why. The entries specific to the redone tanks are here.
Work on the tanks continue. With the leading edges 95% done, I have more space to work on the tanks. Here are the cap flanges after countersinking them to fit the skin dimples. I plan to get locking caps.
Tank skins after matching drilling the J-stiffener and now ready for countersinking along the baffle holes. About 336 holes in fact. Match drilled, deburred, straightened, dimpled and fluted tank ribs visible, as are my in-progress capacitive probe plates.
And, the original crates are starting to look empty.
Okay, so the flap and aileron ribs and other smaller associated parts are elsewhere, but seems a far cry from the first day with the full crates and all the hardware.
Today marks the 250 hour mark. I will take a guess that I'm looking at 200 hours to go. We'll see how this prediction holds up. Update 10-May-18: Bad prediction. The wings required 611 hours.
Also, I liked the idea of a redundant low fuel level warning light. Aircraft Extras has a nice setup, however I could make my own, with the features I want for less, using the same liquid level sensor. After some digging around, I determined that the Honeywell LLE102000 is similar to sensor used with Gopher Electronics having it for the lowest price. I picked up two and will also grab two anti-rotation plates for the install. The sensor is just a simple TTL-type. Just need to ensure a regulated supply which is easy enough. I'll be able to integrate the input into a simple microcontroller setup that I plan to have doing various things.
The bottom of the 26-Jul-13 post shows the install of the sensor.
