Installed the back baffle and zee brackets for right tank. Countersunk the holes in the skin and the zee brackets.
Trying to think about what I will prime prior to assembly. Probably prime the zee brackets, the outside of the back baffle, and the inboard attach bracket that is outside the limits of the tank. Once tank is all assembled, I will spray everything with a topcoat of EcoPoxy. I don't trust that EcoPrime is going to hold up well to fuel. I will probably hold off the EcoPoxy until I have the fuselage kit - I was planning to use it in the tunnel and below the floor pans too.
6/3: after some contemplation and looking at some other peoples logs, I decided to prime the zee brackets and the inboard portion of the attach bracket. I masked off the face of the zee brackets that contacts the rear baffle where there should be some proseal bond.
Went ahead and fabricated the zee brackets for the left tank and then prepped and primed the parts for both the left and right tank.
6/4: Installed nut plates on the zee brackets and then installled nut plates with spacers and installed bearings on the inboard attach brackets. It was really hard to keep the thin shims from distorting quite a bit during dimple and riveting. Hope it doesn't affect the fit of the fairing.
Countersunk holes in fuel caps. Need to research some fuel cap options before I commit to these. Fellow on Facebook is making flanges for the nicer aluminum caps. Might go that route.
I see that the fuel vent clip gets a snap bushings in future steps but I don't see where I'm supposed to drill the hole. Obviously it needs to be done so just did it now. Was difficult to hold while drilling with unibit but figured a way to clamp it to bench with a popsicle stick. Worked out great.
Can of proseal from ACS arrived today so that will let me start on some ribs.
6/5: Drilled the hole for the fuel return line using the VA-140 bing as a template.
Disassembled right tank and scuffed the rivet lines on the skins. I've seen folks tape off the limits, but that seems like overkill. I traced the areas in sharpie prior to disassembly and then just scuffed to erase the marks. I deliberately went well outside the mark to get good bond in the fillet areas. Scuffed then wiped with acetone until clean. Took a lot of wiping to get a white cloth to come out clean.
Then started dimpling the skin. Was almost done with the skin and had the. Skin in a fairly precarious position. I went to adjust the skin while the DRDT2 was still engaged in the previous hole. I'd done this before without problem, but this time the DRDT2 sprung up out of the hole rebounded and came back down on the skin. It made a little pimple, but didn't pierce the akin. It's going to be ok, but whew.
