Tonight was a night of tiny projects. I was able to get all of the AN fittings installed into the left fuel tank. I was also able to get the landing and taxi light wired up and mounted into the right wing. Little project projects big progress!

Wing session

I pulled the left tank off the wing and ran another bead of proseal around all the edges making sure to hit the corners heavily. That seems to be a problem area. I’ll let that all set up and install the internal plumbing… the fuel pickup, vent, and return lines. After that, I’ll rivet the back channel in. I’m hoping to have the tanks done by the time I leave for OSH. It’s unlikely though I’ll get to pressure testing the left tank as I want that to dry for a week or more. Fingers crossed I know what I’m doing now and there’s no leaks in tank two! #fueltank #wing

Continue to chase down the leak on the right wing tank. Also did some riveting on the top skin of the left wing. I decided to switch out the stock fuel senders for a set of CiES senders. https://ciescorp.net/ The are way easier to install and the company claims fuel accuracy to 1/10 of a gallon. They seem way more robust than the kit supplied units. #fueltank

Today was a pretty substantial day. I got the Pio system all wired up and all the electrical wiring laid into the left wing. I was also able to build standoffs so the wires don't interfere with Peter tubes and vice versa. I should be ready to start closing up the left wing and installing the top wing skin this weekend. I'll also be able to retest the right fuel tank to see if I sealed up all the leaks. #wingskin

So with the right fuel tank completely sealed and drying, I need to wait about a week before I can test it. Now it's on the left flap. After that the only thing remaining for the wings is gonna be the left wing.

I pretty much wrapped up the tank today. It was a continued gooey awful stinky nasty mess but it's done! The only thing I have to do with the tank is to attach some of the brackets on the rear side which involves a little bit more prose but not a lot. It's almost there! #fueltank

Starting on the left aileron while the tank pro seal dries.

I cycled between sealing the tank and building the left aileron. Getting the tank together and sealed properly has been time consuming, tedious and messy but it needs to be done right. I have no desire to revisit a leaky tank!!

22:00Doing the tank in small stages seems like the right approach. I bought both the tube and quart can version of the pro seal. This allowed me to mix small batches and the. To take advantage of the tube variant for the larger projects, like riveting the skins on. Not as bad as I had feared.
