Separated the stiffeners.

Used snips to make all the cuts. Doh! Should have peeled the blue vinyl off before I cut them.

Then cleaned them up on the scotch bright wheel, scuffed the mating surfaces and dimpled.

I ordered plexi bits and a zero flute countersink so that I can fabricate the landing light lenses. While I’m waiting for those to show up, I started on the tanks.

Fluted and straightened the tank ribs yesterday. Final drilled all the #40 and #30 holes in all the ribs tonight.

Located and drilled the 3/4″ hole specified in the plans.

Match drilled the rivet holes from the finger strainer flange in the inboard ribs.

Finished riveting the outboard leading edge to the left wing

Finished riveting the outboard leading edge to the left wing with a little help from Remy.

I set the left wing into the cradle and used the pneumatic stapler to attach the carpet suspending the outboard edge.

And that completes cradle construction.

Fluted and straightened the flanges of the tank ribs.

Started riveting the outboard leading edge to left wing

Clecoed the outboard leading edge assembly to the left wing assembly.

Blind riveted the leading edge ribs to the main spar.

I set the the wing upright on the workbench and riveted the leading edge skin to the lower flange of the main spar.

I need a bucking partner to get the upper flange. Hopefully Remy will be available tomorrow evening.

Built wing cradle

Built wing cradles. Used (6) 10′ 2×4’s, (2) 4′ 2×2’s, glue, 3″ construction screws, and 2 strips of carpet 16″ wide by about 5 feet long.

Picked up those nice locking casters from Amazon… 4 Pack Caster Wheels Swivel Plate Stem Brake Casters On Red Polyurethane Wheels (4 inch with brake)  I bought two sets. Might try putting the other set on one of the work benches. Maybe get some more for the other benches if I like it.

Riveted outboard leading edge to right wing

Completed the right outboard leading edge by riveting the landing light bracket and J channel stiffener in place.

Clecoed the outboard leading edge to the right wing.

Blind riveted the leading edge ribs to the main spar. I couldn’t get the rivet puller square to the river so I fabricated a wedge to safely pull the rivets at an angle. Thanks to Jared for the reminder on this technique. I had originally read about it in section 5 but had forgotten. I ended up using a piece of left over trailing edge wedge. I cut of a small section about half an inch long and drilled a hole in it to accommodate the tail of the blind rivet.

Riveted the leading edge skin to the bottom flange of the main spar.

Riveted the leading edge skin to the top flange of the main spar. Remy bucked for me.

img_2567

I made a home depot run and picked up a bunch to 2×4’s to construct a wing cradle.

I messed up and stripped a couple of screws that I used to attach the inspection plate to the left leading edge. Need to order a screw extractor.

Riveted right outboard leading edge skins to ribs

Riveted right outboard leading edge skins to ribs with some help from Remy.

Placed the leading edge back into the cradle and clecoed the J channel stiffener and the landing light bracket in place. I’ll rivet those in place tomorrow. It was getting late.

Sophie deburred the edges of all the tank ribs for me while I was in Toronto this week.
