Arlington 2018 and ... more deburring

July means that its Arlington fly-in time.  I don't know what it is about this particular fly-in that I enjoy but I suppose its the flight and camping with friends.  The airshow this year was not as impressive as the past few years but it was still very good with some great pilots.  There was a new "act" this year in the form of a 60 drone "swarm" after dark.  I almost missed it (I fell asleep in the tent before dark) but Jeff woke Harry and me up and I'm glad he did.  The drones were amazing!  Highly recommended if you ever get a chance to see one of these performances.

I had somebody ask me the other day what I meant by "deburring".  Well since I just started working on the flaps I figured the timing was good to show you what I mean.  I always try to edge debur as the first step in any new assembly...it tends to save on bandages.

The weather this year was almost perfect.  The sunset in this picture was spectacular. 

Of course we had to send this selfie to a friend who "forgot" this was Arlington fly-in weekend.  The best part was he was still at work while we were here.  Sorry Martin! (not)

I thought the scene for the Friday airshow was very pretty so I took this picture.  Some ominous looking clouds in the background but they sure made for some great pictures.
Here is the pile of parts that need deburring for the flaps alone.  There are probably 50 different items here.  On this pile alone I probably spent 6-8 hours deburring.

This is what the edge of a rib looks like when it comes from Van's.  See all the rough edges and burr's?

Here is what it looks like after several minutes of filing and buffing.

Even the skins need to be deburred.  This one wasn't too bad.  Some of the skins are so sharp they cut fingers quite easily.

A little hard to get the focus right but you get the idea.
