Driled out brass bushings for aileron bellcranks. (Used drill bit instead of proposed straight reamer, which worked fine.) Got bellcranks to operate very smoothly -- took lots of time to get bushings to fit just right by chucking them in the drill press and holding strips of 600-grit sandpaper against them.
Cut W-816 (large) aileron pushrod tubes to length, drilled end caps, deburred, cleaned, primed everything, assembled and riveted end caps. Test-fit L wing pushrod to bellcrank.
Will reorder two end caps for R wing W-816 pushrod, because edge distance is not sufficient. Will use existing pushrod as a drill guide, since its edge distances are fine. (The reason I messed up these holes is that I wrongly took an artist's view of the "look" of these pushrod assemblies, assuming that the beveled surface of the end caps would make a flush intersection with the pushrod. In reality, the end caps should be pushed into the rods further than you'd think by looking at them.)
