Sanded and attached horizontal stabilizer tips

Sanded and fit the HS tip to fit. Before I paint the airplane, these will need to be filled and finish sanded.

Final drilled #30, dimpled the skins, and machine countersunk the tip.

I picked up a pneumatic rivet puller at Harbor Freight yesterday. I used it to set the rivets and attach the tips.  So much nicer the the manual puller!

This completes the work on the horizontal stabilizer and elevators. So I’ve moved them to a safe place until I’m ready to final attach them at the end of the build.

Attached left elevator tip

I final drilled #30 the elevator skin to the tip. Then I removed the tip and countersunk the holes.

img_2068

I dimpled the holes in the elevator.

img_2069

I had to remove the counterweight to dimple the forward two holes. Then reinstalled and re-torqued the nuts.

img_2070

Installed the tip with CS4 pop rivets. I’m thinking I might replace my pop rivet tool. I’m getting a burr on the top of all of the rivets and I’ve had several break off in the tool. I’m careful to keep the tool perpendicular to the work but this keeps happening. A while back, a mandrel got jammed in the tool. I disassembled it to remove the mandrel and reassembled it. But I think the jaws are not grabbing properly now.

In other news, you can see that after trimming and sanding the left HS tip, it fits nicely. The right tip is another story. I think I neglected to final fit it after I sanded the foam or perhaps I seated the foam too deeply. In any event, it spread the tip about an eighth too far and now the tip wont fit between the top and bottom skins at the spar. I’ll noodle on how I might salvage the part for a while and If I can’t I’ll order a new one. My best thought at this point is to take a 1/8″ wedge out of the middle of the foam/fiberglass with a saw and then put  another layer of glass over it.

Riveted aft deck

The nut plates and new static line that I ordered from Van’s showed up today. I installed the static line.

IMG_2013

Riveted the nut plates in place.

IMG_2004

Riveted the aft stiffeners.

IMG_2006

Countersunk the upper cover plate attach holes.

IMG_2007

Installed the left cover plate. The other one is on it’s way from Van’s. I bought some stainless screws to install the cover plates.

IMG_2008

I riveted the aft deck in place.

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.

Top skin assembly

Broke the edges of the top skin with the edge roller. Peeled the vinyl from the rivet lines and dimpled the top skin on the DRDT-2.

IMG_1990

Dimpled the top rib with the squeezer.

IMG_1991

Dimpled the top skin doubler with the squeezer.

IMG_1992

Dimpled the stiffener and back riveted it to the skin. Back riveted the doubler and riveted the rib with the gun and bucking bar.

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

Scuffed and primed the side skins.

IMG_1956

 

Machine countersunk all the holes in the longerons.

IMG_1958

 

Dimpled the remaining stiffeners.

IMG_1960

 

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!
