The last of the push tubes are now complete except for painting the outside. I did prime the insides as before by pouring in some Akzo epoxy primer and taping off the ends. This works well as long as you use enough paint and move the tube in all directions for a few minutes, then pour out the excess. Also today I added 2 nutplates for the center flap bearing block. It sounds simple, but it was very difficult to get them drilled, mounterd and riveted.
