Time: 7.0 Task: Got a lot done today! I finished all
the drilling and fabricating on both flaps. I then completed
duburing the left flap, dimpling the parts, and started deburing/dimpling
the right flap.
started on the right flap today. Clecod the skeleton onto
the bottom skin and match drilled holes to #30.
I then clecod the FL-701 top skin on and match drilled all
skin to rib holes #40.
Next came the FL-706A/B mounting brackets. I used the same
method as I did on the left side. Worked just as well and
was twice as fast!
Enlarging the nutplate hole to 1/4" for the rod-end bearing
that will control flap movement.
came the hinges. I marked up 1/4" from the bottom and
used the other hindge as a straight edge to draw a
Then I used two cleco clamps to hold the hinge in position.
I started by drilling holes above each rib and putting a cleco
in place. I then split the distance and match drilled those
holes and put clecos. I did this until there were no more
than 2 undrilled holes in a row. It went pretty quick with
the air drill to drill the rest of the holes.
Right flap hinge in place below. I then removed the flap and
skin, and countersunk the FL-703 spar so the dimples in the
skin would set in the spar.
I finished up the day by deburring all the holes in the left
flap and dimpling. I then moved onto the right flap and was
able to debur/dimple both skins before calling it a night.
Dimpling the FL-702 bottom skin.
On the left side of the table are all the deburred and dimpled
parts for the left flap. On the right side are the right flap
skins, also finished.
