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.

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.

Hey–this thing’s starting to look like an airplane.

Scuffed and primed the side skins.

Machine countersunk all the holes in the longerons.

Dimpled the remaining stiffeners.

Dimpled the skins.

IMG_1961

 

Clecoed everything together.

IMG_1965

IMG_1964

In my excitement over putting all this together I neglected to peel the the blur vinyl from the rivet lines. I’ll have to remove some clecos and do that before I rivet.

I also riveted the aft bulkhead to the aft bottom skin.

Bulkheads Riveted

Clecoed and riveted the F-01412 aft bulkhead and tie down bracket.

IMG_1927

Clecoed and riveted the F-01411 bulkhead and aft horizontal stabilizer attach bars.

IMG_1928

Clecoed and riveted the F-01410 bulkhead and forward horizontal stabilizer attach bars.

IMG_1929

Clecoed and riveted the F-01407 bulkhead.

IMG_1930

Clecoed and riveted the F-01408 bulkhead and rudder cable bracket. Also added the stiffener clips to the bottom of the bulkhead. I believe that these were added to revs of the kit that came out after service bulletin 18-09-17 was issued to address cracking in the forward bottom skin.

IMG_1932

Riveted nut plates to the battery angles. So why are these called battery angles when they have absolutely nothing to do with the battery? In fact the battery isn’t even located in the tail. My guess is that these parts were originally part of the RV-10 kit. The RV-14 borrows parts from other RV’s. So while in the RV-14 they are part of the aft bell crank assembly, in the RV-10 I’ll bet they formed part of the battery box and simply retained their part number and name when they were introduced to the RV-14. If anyone knows for sure, please comment.

The forward nut plate holes do not get nut plates as they are not applicable to the RV-14.

IMG_1933

Riveted the battery angles to the bell crack ribs.

IMG_1934

Riveted nut plates to the F-01406B bulkhead.  Note the discolorations at the bottom of the bulkhead. I managed to scratch the primer moving the part before it was fully cured. So I touched it up. Apparently re-shooting P60G2 creates this discoloration. It seems to have dried properly and doesn’t seem to be problematic; just unsightly.

IMG_1935

Riveted bell crank ribs to the F-01406B bulkhead.

IMG_1936

Clecoed and riveted the F-01407 bulkhead to the bell crank ribs.

IMG_1937

Dimpled the forward bottom skin with the DRDT-2

IMG_1939

Lots of dimples!

IMG_1940

Dimpled the stiffeners.

IMG_1942

Clecoed the bell crank ribs, bulkheads, and stiffeners to the bottom skin.

IMG_1943

Ready to Rivet!

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.

Riveted the Forward Spar Assemblies

Riveted the gusset to the left root rib and riveted the inboard and outboard halves of the tip ribs together. Spent a bit of time with a square and hand seamers tweaking to ensure everything is straight.

IMG_1803

Riveted the tip ribs to the spars. Riveted the hinge reinforcement plates and nut plates to the spars.

 

IMG_1805

Clecoed and riveted the counterweight skins to the tip ribs.

IMG_1807

Riveted the elevator horns to the spars.

Assembled Trim Tab

Bought a 3/4″ MDF panel at Home Depot. Leveled it out on the bench and shimmed the dead spaces with sheets of paper to create a flat surface.

IMG_1794

Prepped the skins, spar, and trailing edge with isopropyl.  Mixed up a small batch of fuel tank sealant and put a thin layer on each side of the trim tab ribs and set them in place. I used the 3M VHB tape on both sides of the trailing edge. Used clecos to align it with the bottom skin and set it in place. Then I clecoed the top skin in place along the spar and trailing edge. I peeled the paper from the VHB tape between the top of the trailing edge and the top skin removing clecos as I went to avoid tearing the paper. I replace the clecos to clamp the whole sandwich together while the tape sets up.

IMG_1795

The sealant is ridiculously sticky and smells like ass.

IMG_1796

I riveted the top skin and hinge to the spar.

IMG_1797

All done!

IMG_1798

Weighted down the skin with a board and some 2×4’s to ensure contact between the skins and the ribs until the sealant sets up. The spec sheet says there is a 6 hour cure time for the B 1/2 sealant I used.
