No skydiving today (again; I'm getting a little bit fed up with the weekend weather these days...). Jackie has had to work today, so no riveting on the wing until she comes home. So what to do? Since I had already previously assembled the left aileron skin/stiffeners, I decided I may as well carry on with that. So 3ΒΌ hrs later, I have a fully matched drilled and assembled left aileron. I'll see about getting all the bits deburred and dimpled, etc for when I primer the aileron attach brackets for the right wing: do the whole lot in one go.
