I got the rest of the ribs on the left tank sealed up. I’m going to let it set up for a few days, then rivet it. I’d be able to use this time to seal the ribs to the other tank, but unfortunately, I don’t have enough clecos!
Anyways, here it what things look like at this point:

Will the wing tanks be pressure tested?
Yup. I’ll test for leaks twice on both tanks.
First, once the tank is complete except for the last rear baffle, I’m going to fill them with water and look for any leaks. It’s much better to catch leaks at this point, as you still have access to the inside of the tank to fix them.
Then after the tank is fully sealed, they get pressurized to a few PSI, and you spray soapy water and look for air bubbles that indicate air getting out.
We finally get a shot of your fancy garage shoes – what an oh so functional gift from your lovely wife!
I love my croc-knock-off internet-special garage shoes! When you’re dealing with aluminum shavings, proseal, and other stuff, and go in and out of the house, shoes that are easy to slip on and off are essential!
And thanks for my ugly shoes! You’re the best!
Those are heavy duty croc upgrades. Leave it to LandsEnd to make super ugly super functional shoes!
