Longerons, Doubler Plates Ready to Prime
Today I went out and experimented with some scrap pieces of aluminum and made some test pieces to get the countersink depths of the longerons just right (just look at the last couple days entries and you'll see where I was concerened about this). So once I was satistfied, I recountersunk the longerons only at the side skins forward. I need to take off just a hair more to get the countersinks just right.
Ok, both longerons and all underlying pieces are countersunk (again). Then I scrubbed the longerons and doubler plates down with Scotch-Brite pads to get them ready to prime.
I also masked off the joint where the center skins overlap the aft fuse...there was some very light corrosion going on there so I wanted to take care of it and make sure it doesn't come back. I'll probaby throw a little alumiprep on there also.
I'm also experimenting with paints for the interior. I had primed this piece the other day with my self-etching primer and today I painted with an acrylic enamel I'm considering using. After about 30 minutes it was fairly durable but would still scratch the top surface of paint (not down to the primer). The can says it can take 5 days to fully harden so I'll check it this weekend to see how durable it is. As far as the look goes, this is pretty good. I can live with it since most of the interior is probably going to be upholstered anyway.
