Riveted the top side skins

Clecoed and bolted the vertical stabilizer to the aft fuselage and match drilled the upper attachment holes.

Rolled the aft fuselage on its side to rivet the top side skins.

Finished riveting both top side skins to the aft fuselage.

Clecoed the top skin in place.

Tomorrow I’ll rivet the top skin and that will complete the aft fuselage.

Dimpled top side skins and aft deck

Dimpled the top side skins. I used the squeezer for most of the holes and the DRDT-2 for the ones the squeezer couldn’t reach.

IMG_1998-1

I clecoed the side skin on. And I actually remembered to peel the rivet lines this time.

IMG_1995-1

I dimpled the F-01409 frame.

IMG_1996-1

And the aft deck.

IMG_1997-1

I clecoed the aft deck, F-01409 frame in place along with the Horizontal Stab Attach Bar Support Angle and deck angle. I clamped the attach bar to the support angle and match drilled. I also match drilled the deck angle to the aft bulkhead.

IMG_1999

I dimpled the cover plates for #6 screws as well. Then I realized for the first time that the cover plates are not symmetrical. <moan> And of course one is now dimpled the wrong way and primed on the wrong side. I went to order a new one from Van’s web site only to find that F-14112 does not exist in their parts inventory and it’s an hour after closing time. Oh well. I’ll call the tomorrow. No big rush given that I’m almost out of parts and my wing kit isn’t scheduled to ship for more than a month.

More work on bulkheads

Modified the bottom of the 1408 bulkhead.

IMG_1893

Deburred and dimpled all the 1407 and 1408 bulkhead parts.

IMG_1895

Separated, deburred, and dimpled the bell crank ribs.

IMG_1896

I realized when I went to drill the battery angles that I somehow modified the wrong one. I could swear that I marked these parts carefully before I separated them but it appears I switched the A and B markings. I don’t think this will be a problem though. I just needed to modify the correct one. The modification to the wrong one is not consequential.

IMG_1897

Once I fixed that, I drilled and countersunk all the nut plate holes and match drilled the angles to the bell crank ribs. I deburred and dimpled the 1406 bulkhead as well.

IMG_1898

I think next weekend I’m going to have two solid days of scuffing and priming all these parts.

Finished Elevators and Worked on Aft Three Bulkhead Assemblies

Yay! Rivets came in the mail and I was able to finally complete the elevators.

IMG_1877

Cleaned up the edges and deburred the longerons and J stiffeners.

IMG_1875

Matched drilled the aft bulkheads to the VS aft spar.

IMG_1876

Countersunk the tie down support.

IMG_1882

Dimpled the bulkheads. I think I found a problem with the plans. They called for dimpling the #30 holes in the web of the bulkhead. Note the two dimples along the edge of the tiedown bracket. they are keeping it from sitting flush against the bulkhead. I’ll likely need to undimple these holes somehow.

IMG_1883

Match drilled the next bulkhead to the HS attach bars and dimpled the flanges.

IMG_1885-1

Likewise with the next bulkhead…

IMG_1887.jpg

Ready for deburring, scuffing, and priming.

Began Work on the Aft Fuselage

IMG_1855

The aft fuselage build begins with cutting and trimming parts. Separated the rudder cable guides.

IMG_1853

Separated the various j-stiffeners, longerons, and battery angles. Modified several of the parts according to the plans. Dimpled a couple. And straightened the HS attach bars.

IMG_1854

This was the first nice flying day we’ve had in the Atlanta Area in a week or so. So Sophie and I took advantage and did a little sightseeing in the Skyhawk around north Georgia. Absolutely beautiful flying day.

We also paid John and Bernie a visit in the McCollum control tower after we got back and things had slowed down a bit at the airport.  They really had their hands full today. It was very busy with the nice weather. On the way out we were one of six flights waiting for departure and they had three in the pattern, several arrivals inbound and a transitioning aircraft all at the same time. These guys are awesome at what they do.

Disassembly and Deburring

Clecoed and final drilled the elevator horns to the inboard ribs and spars.

IMG_1766

Cut the trim tab pushrod parts and the trim tab horn parts.

IMG_1767

IMG_1768

Deburred everything and got about half the parts scuffed and ready for primer. Next I’ll scuff the rest of the parts, peel and scuff the skins and prime everything.

IMG_1771

My pint of fuel tank sealant arrived from Sky Geek today. I’ll use this to glue the foam ribs in place.

More Work on Elevators

Jared Solomon and Wes Greer stopped by today and helped move the elevators along. I really appreciate having experienced builders helping me out.  Things went really fast and their advice is incredibly valuable. Had lot’s of fun building together, too. Thanks guys!

Today we final drilled the tip ribs to one another and to the counterweight skins. We cut the foam trailing edge and trim tab ribs. We trimmed and deburred the trim tab skins. We trimmed the right elevator aft spar. We bent the closeout tabs on the left elevator skin. We fit and drilled the trim tab hinge. We clecoed everything together and fit/trimmed the elevator trailing edges.

IMG_1759

Jared and Wes went home and I continued building. Not even ten minutes unsupervised and I screwed up! I misunderstood the interface between the trailing edge extrusion and the elevator wing tip. I removed way too much material from the trailing edge. I didn’t realize that the wing tip would be trimmed and butt up against the trailing edge. Had I read forward to the “Empennage Fairings” section, I would have understood how this went together. Oh well… Ordered a new trailing edge from Van’s.
