Wing Ribs Primed, Riveting begins

Since the last post, I have completed the priming of the ribs and flap brackets.  I used Sherwin Williams P60G2 which I really like once you get the hang of it.

I chose to use a small Harbor Freight gun which is really a touch up gun and only holds 4 OZ of mixture.  It has a .8 mil tip and seems to work well.  You do end up having to reload quite a bit but I have found so far that the overspray is minimal and it not that inconvenient to mix again. I may invest in a larger gun but for now this will do.  Initially I had too thin a coat of primer on there.  I could feel it but there was no real noticeable green color.  I resprayed and am happier with the coverage.

For the flap brackets I first started with the Pneumatic Squeezer which I found to be difficult for this in terms of reach and my ability to align everything straight.  I went back to a method which I really like a lot which is to backrivet using a c-frame.  It keeps everything aligned and gives me more control.  I did notice that there seems to be a small gap between the thick flap material and the rib on at least one rib so far, so I am going to again check that the flap brackets are flat/straight.

Pictures will be up when I have some more time.
