CH801
Slow, ugly, and rather slow.
Starboard Wing
05 Sept 2008 ~


See the edge distance on the hole at the far right? That's what I got by following the directions. Decided to try my own method instead.

Here's the part I made (after three trys). I think I have much better edge distance than the part where I followed directions.

Jig used to bend stiffners and drill to nose ribs.


Drilling stiffner to nose rib. The stiffner is under the rib.



Fabricating a nose rib skin stiffner. Here I used a center punch to locate releif holes that I drilled out.


Cutting out slots in the nose rib skin stiffner. Here's where the releif holes come in.

Deburring.

Here I have the nose ribs and wing ribs from both wings - but just the ribs that have flap or slat brackets. Each has been located at the factory. I'm drilling out everything to size (#20).



Rear spars from both wings. Each spar consists of two pieces joined with a splice plate. Note the cafecito in the foreground.

Ben getting the spar lined up on the table.

My lightening holes are facing forward, not backward like the manual shows (or like what I saw on other builders' sites). So I had to be a little creative on how the spar was clamped to the 90 degree jigs.

90 degree jigs.



Got the nose ribs located. The wing is upside down (top is on the table).

Working on the wing ribs.

Used a short extrusion to line up the bottom of the rib to the bottom of the spar.

Wing ribs located.

Drilled everything to size (#20). I did the final drilling with both nose and wing ribs clecoed.


Rear spar clamped in place.


This is the trailing edge of the root rib. I cut off the flange I'm pointing at and replaced it with a Std L so that I could modify the length of this rib.

Bottom I/B skin located flush with the front edgr of the spar.



Drilling the O/B bottom skin.

Overlap between the I/B (right) and O/B skins. The final wing will have the OB skin on top of the IB (opposite of what is shown).

The overhang will get trimmed later on. Remember the wing is upside down so the skin you see is the bottom skin.

Root rib rivet line.

Trailing edge of the root rib modified with the Std L.

Located the nose skin.

Bottom nose skin is on too.

Making a cut out for the main strut attach bracket.

Doubler for the main strut brace. This doubler goes through rib station 4.

Doubler.


Little creative rivet locating.


Getting ready to clean / prime.

HVLP gun from Harbor Freight.

After priming, the wing gets re-assembled on the table upside down like it was before.

Here the skeleton is all riveted and I'm putting the bottom skins in place.

Riveting. This goes pretty fast once eveything is in place.


Carmen and I took the wing out of the garage to flip it over so we can work on the top side.

Here's the wing with the bottom side on the table.

Here, I'm getting ready to locate the top I/B skin. Havine already done the bottom, this felt pretty easy.
