Wing Assembly Log, page 3
2/27/98; 6.75 hrs; riveted left ribs to rear spar; dimpled left bottom skins and clecoed to skeleton; rigged right leading edge ribs; trial fitting of right leading edge skin.
A threaded rod is rigged through the tooling holes of the leading edge ribs to serve as a jig. Nuts are run onto the rod to hold the ribs in position. Chucking the threaded rod into a drill makes a tedious job slightly less tedious.
Little scraps of stock combined with clecos to clamp the leading edge flush with main skins.
First fitting of right leading edge. Everything lines up!!
2/28/98; 5.0 hrs; drilled, dimpled, riveted right leading edge; right leading edge complete.
3/1/98; 2.75 hrs; jigged left leading edge ribs; drilled left leading edge skin to ribs; dimpled leading edge ribs.
3/2/98; 6.5 hrs; dimpled and riveted left leading edge skin; installed Duckworks landing light mounts in right leading edge; bolted right leading edge to spar, ready to rivet.
The Duckworks kit includes templates for cutting a hole (!!?!) in the leading edge.
A cut-off wheel in a Dremel tool makes a neat cut if you have a steady hand....make several passes and take your time in the corners. The 2" Scotchbrite wheel will polish the edges nicely.
Another template was transferred to lite ply and the holes drilled for plate-nuts in the ribs. This would be VERY interesting on a completed wing!
The Duckworks kit uses the reflector and bulb from an after-market automotive driving light. The reflector will mount in this plate. The mounting holes are over-sized to give an adequate adjustment range.
Here is the plate installed (looking at the bottom of the wing). The instructions assured us that the lens will fit through the opening! Overall, I would give the Duckworks kit an A- for fit, completeness, value, and hopefully, effectiveness.
3/3/98; 4.5 hrs; installed landing light mount in left leading edge; riveted both leading edges to spars.
