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.
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.
Also drilled the holes for the fuel return line in the inboard rib using the VA-140 bung as a template.
Then started dimpling the skin. Handling everything with gloves after initial cleaning. 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 skin. It's going to be ok, but whew.
6/6 am: scuffed faying surfaces of all the ribs and cleaned with acetone. starting to dimple. Countersunk the holes in the T-1005 attach bracket. Not specifically called out, but it is 0.063" so it wasn't going to dimple. Starting to seem more instances of Van's assuming you'll figure it out by now.
6/7 am: finished all the dimpling before work. I think we are ready to start assembly.
