8th:
Taking a look at the Jabiru 3300, which will reside in its
crate until there is a fuselage on which to hang it. Finished
dimpling the upper side of the ribs, dimpled the upper skin,
and clecoed. This is the start of the third year of
construction, with rather sporadic build schedule. But, with
the engine on hand, there is incentive to complete the
airframe more quickly.

9th:
Turned the wing over to dimple the bottom of the forward ribs
and skin. Umm, not good planning. This is a very awkward
position, standing on a chair. Long session today, completed
dimpling all 12 ribs and the skin, and, with the help of five
hold-down straps, pulled the skin into place and clecoed. The
pitot-static nutplates on the rib side are slightly canted
from tangent to the hole, so they overlap the rib flange by a
hair. Tolerances are very tight in this plane; measure,
measure, and measure again. Will need to ease the edge of the
flange before final assembly.
