Prepped and painted aileron hinge brackets
May 25, 2011 – Over the last week or so I’ve worked on the aileron hinge bracket assemblies.
I assembled them all using clecoes and I test-fitted them on the aft spar.
Here’s the outboard and how it fits:
And the inboard. I discovered that I’ll have to slightly modify the brackets to clear a fastener through the skin at that point:
When I clean up and deburr pieces that layer together like these do, I usually clean the edges as a unit. So while they wre clecoed together, I polished the edges using my usual Scotch-Brite pad in a die grinder. This aligns all the edges together. I just sanded the corner to clear the rivet and rounded that lower edge so the bracket fits nicely in the radius.
I took all the pieces apart, keeping them in groups. I cleaned and alodined them all, then primed.
I’ve read that primer in the counterbored hole for the bearing interferes with that bearing, so I found a socket that fit the hole, and rolled it in tape to fit. I placed the socket in each hole as a mask, and painted. The holes came out nice and clean.
