Drilled out holes for screw attachments to #19. Used jig to drill attachment holes for nutplates—really like this tool. Also dimpled F804N bulkhead cap to use CS4-4 blind rivets later in the build. Deburred, cleaned all parts, washed with Dawn & MEK—then shot primer. After primer dry, I used the pneumatic squeezer to set the NAS rivets securing the nutplates. Squeezed the AN470 rivets attaching the angle to the mid cabin cover.
