Mark and cut out the holes for
the aileron pushrods. You can use a Unibit to remove the major portions
of the area, and then use a round file or a rotary cutter in a die
grinder to remove the remaining portion.
I bought these from Avery as I
have seen their use referenced throughout the building of other parts,
and figured I will need them along the way.

The bit will drill a ever
increasingly larger hole with the cutter, there is a large open
face on the bit to evacuate the metal as it comes out. It is very
sharp and takes the metal out very nicely. If you look closely
inside the hollow part you can see the hole diameter sizes in
fractions of inches when it reaches different heights up the
cutter.

The hole is increased in size up
to the largest part of the drill, there is a diameter scale up the
middle of the hollow part for reference if you need it.

I am becoming a tool junkie,
Avery and Cleveland will love me. Both companies are great to deal
with and really know their stuff about tools RV builders
need, and both have great websites for online ordering.
This is a nibbler and really
wasn't that expensive and I am sure will come in very handy many
more times. It allows you to go up through the center hole and
take little "nibbles" out of the metal, See next picture

Arrived just in the nick of time
to finish off the aileron push tune hole before priming the Sioux
die grinders with a great assortment of wheels and cutters. They
are really neat little units and look like a very good quality.
Ordered from Avery, I was just going to order the one but they
said they were on sale and who can pass up a sale, just like
Christmas around here with all these new toys, more just like hell
week when wife sees credit card statement.

Avery)

Parts are primed and ready to
rivet rear spar. The plans have switched from rivet callouts to a
legend type symbol on the plans. Wow they are like those shapes of
different road signs you have to identify by shape on your drivers
license written test, I could never remember them. I decided to implement
a color coding and use different highlighters to mark the plans
for the different rivets and accompanying foot notes which there
seem to be a lot of , rivet this with that and so on, so it will
also force me to read all the footnotes and maybe get most of the rivets
in the proper sequence.

I started
squeezing the rivets for the reinforcement plates to the spar and
learned a couple of things. I forgot to dimple the skin holes and
I remember somewhere it says they will be hard to do because the
plate gets in the road, so dimple them before you start to rivet.
I started
squeezing the rivets with the machine head under the flange where
you can't see if you are on it properly and the shop heads were
bent over. Drilled the few rivets out I had tried put the machine
head on the side where I could see it. It helped me to get
the yoke vertical and a good look at the rivet set on squarely and
then they squeezed OK. Point is when squeezing rivets you need a
good look-see at how the rivet set is on the machine head and the
shop head will take care of itself
