Here are the completed flaps. I finished the left one last night, and the right one today.
I have been building both flaps in parallel. After I do a step on one flap, I do the same step on the other. This saves a lot of plans reading and setup time.
The left aileron can be seen in the jig in the background. I will start riveting the skins to the skeleton the next work session.
The step ladder visible in the background is used to hang a plumb bob from to make sure that the ends of the aileron and flap jig are vertical. This makes sure that the surfaces are built without a twist in them.
I made good progress on the two weeks of vacation that I just finished. It looks like I am heading back on the road for two weeks, so the project stops again.

The normal construction sequence is to build the main wing structure, then the fuel tanks, and finally the ailerons and flaps. I decided to start with the ailerons and flaps so that I could delay any work on the main wing structure. The fatal accident of RV-8 N58RV was caused by an in-flight separation of one of the outboard wing sections, so I wanted to wait until the accident investigation was complete before doing any work on parts that might see a design change.
Here is the skeleton of the left aileron all clecoed together.
Now I have to do is deburr the parts, prime all the parts for both ailerons, and then I can rivet the ailerons together.
Unfortunately, I am heading back on the road again, so nothing more will happen for a week or so.
Note - The N58RV accident investigation eventually put my concerns to bed - an extensive engineering review and static testing by outside consultants showed that the wing structure as designed is adequate.
