And the aileron actuation continues

I have lost some time on this chapter due to the instructions being less great than the other parts have made me expect.

For instance, yesterday I primed the inside of the collars before realizing that I need to grind and polish the parts to make them fit, so now I have to wait for the parts to dry to be able to grind and polish and then I need to re-prime the parts. Earlier parts of the manual have been good enough that you can just follow and perform the steps one by one, here you really need to read ahead and adjust the order of the tasks.
