I haven’t posted anything since January 3rd (Post # 4), but I’ve definitely been making small strides on the plane. I’m currently in the stage of preparing a lot of smaller parts/pieces and NOT showing any real physical progress! Lots of fitting, grinding, fitting, sanding, fitting, and sanding some more, etc. I haven’t posted those work session because there really wasn’t anything to see. However, with the work yesterday and today, I thought it was worth catching the site up.
Each of the Inboard Aileron Hinge Bracket Assemblies have seven pieces (14), each of the Outboard Aileron Hinge Brackets have 4 pieces (8), and three Rear Spar Doublers (3).....25 pieces total. Each piece needed some degree of drilling, sanding and edge work. So, I worked on these parts a little bit each of the last couple days.
These are the seven pieces that make up the Inboard Aileron Hinge Bracket Assembly. These parts were supplied as part of SB 16-03-28 for the reason discussed in a previous post.
These are the four pieces that make up the Outboard Aileron Hinge Bracket Assembly. These parts were supplied as regular Wing kit parts and are NOT associated with the SB.
I’ve shown the three Rear Spar Doublers in my previous post, but since I mentioned them again here.....here they are.
Here are the completed Left and Right Inboard Aileron Hinge Brackets. In the areas circled, both Angle Brackets had to be trimmed, filed and sanded to match the angle of the adjacent Side Brackets (Doublers). Here you can see the final product after I matched the two angles. Both of these Assemblies also needed the #30 holes to be final-drilled. The “fin” sticking up will serve as the Aileron stops once they are installed on the Rear Spar.
Additionally, the three holes in the Inboard Aileron Side Brackets were countersunk to accept the head of an AN426AD4-7 flush rivet (on the outboard side of the Bracket). In the picture below, the holes are marked 1, 2, and 3 on each piece. The remaining holes will receive AN470AD4-7 universal rivets.
As with the Inboard, the Outboard Aileron Hinge Brackets also had holes that were countersunk. You can see these holes marked below with 1, 2, 3, 4, 5, and 6. AN426AD4-7 flush rivets will also be installed these countersunk holes. AN470AD4-7 universal rivets will be installed in the remaining holes.
As I mentioned, this post encompasses work sessions over the last few days. Yesterday, I treated a few of the parts with Alumiprep and Alodine. Tomorrow, I will treat the remaining parts/pieces and they all will be ready for Akzo priming.
