Brief Description:  Deburring rear fuse

I have been working the past three days taking one side apart
at a time and deburring every hole in the skins, bulk heads and longerons.
This is a time consuming process but using my little electric screw driver
with a deburring bit from Avery tools makes the job much easier than using
the twirly deburring tool.
After the plastic was removed from the side skins and all of the holes deburred,
it was time to bend the front edge 7 degrees inward. This makes a better fit
with the forward fuselage cage skins. Look closely at the third picture and
you can see the bend in the right side skin.
I bought the bench brake shown in the second picture back in 1999 when
I built my first Sonex. I have used it a lot since then. Kinda pricey but
makes nice crisp bends in aluminum up to .040 gauge. You can see
my set up using a folding chair and a couple of 1" X 4" boards to hold
the long skin level during the bending process. If you look closely you can
see the small c-clamps I use to hold the skin and bar in place.

The third picture is the right side ready for riveting. I will wait until I get
the entire aft fueslage clecoed in place before doing that.
