Aft Fuselage

RV 14 Build September 13 & 17

Aft Fuselage

My replacement horizontal stab attach bar support angle showed up and I was able to get it cut, prepped and primed on the first day of work.

This is the plans for the rework.

I have a better understanding of what the angle does and where it sits, it definitely helped in the fabrication knowing how it will be used.

Overall Im happier with this version of the support angle than the first, I did have to go back and hit it with a little more primer after it was done drying I noticed my coverage on part wasnt great.

Time to work the install!

Getting ready to match drill the hole that I messed up the first time around.

Match drilling successful this time!

Pretending to rivet for the Camera lol

Done! And this completes Section 10: Aft Fuselage

RV 14 Build August 10 & 27

Aft Fuselage

Been moving slow this August getting the airplane built. Seems like I keep making little mistakes that require parts or tools. Oh well, finally a little progress. Matt came to the shop and helped me put the aft fuselage back together to the point that I had it before I decided to drill everything apart and re-do my work.

Getting the shims between the tail spring mount and the bulkhead. You can see in this picture though the clekos in the horizontal stab mounting bars...I ran out of those larger rivets. Decided to press forward and install the bulkhead and put those rivets in later.

The bottom aft skin came together much nicer this time around.

Finally moved beyond where I had it 2 months ago, note to self, slow down and go home if you dont have the tools, parts, or energy. A day or 2 is shorter and cheaper than 2 months or rework!

Another view of the side with almost all of the rivets in!

The larger rivets came in, I used the squeezer where I could and drove the remaining ones, glad this worked out.

Optional dimpled access panels need these different nut plates that don't come with the kit, ordered them from aircraft spruce, the install went mostly smooth. Had to drill out 1 and redo it.

Finally the entire aft sides are done!

Work on the aft deck!

Cruising along!

And my mistake for the day... Drilling this bracket I didn't have the double plate under it so I drilled the holes slightly to low...New part ordered.

You can see with the double plate riveted to the deck how the hole in the bracket is higher than the hole in the stabilizer mounting bar. I probably could "fix" this but i've learned it usually faster and easier and causes less damage to get a new part and do it again.

 Moving forward anyway! Drilling the mounting holes for the vertical stabalizer!

Oh man looks like and airplane!

The holes start as #30 and need to be perpendicular to the bulkhead and 1/4". I step drilled them with 3 drill bits and finished with the 1/4" reamer.

Boom airplane tail!

Aft Fuselage mistake repairs

RV14 Build August 2

Aft Fuselage

All the replacement parts for the aft fuselage lower aft skin came in so i prepped them for primer, primed, and started the repairs. 

I forgot to order rivets to build this bulkhead so Im stopped dead in my tracks again!!

Or am I! When I was as Oshkosh I was talking with one of the vans engineers about my poor drilling out of the j stiffener rivets when I was drilling out the aft lower skin. He urged me to replace the whole stiffener rather than splice in a new one or build a doubler. I was apprehensive since drilling rivets is what caused most of the damage Im now repairing, but i decided I needed to learn to do that better and took his advice. It worked perfectly. Removed the old one with almost no issues and installed the new one once the paint dried, with Matts help on the rivet gun again!

My "snowman" drill holes that need to be fixed

View of the old one.

View of the New one, looking O so good!

Front end of the new one, runs the whole length of this section.

Getting ready to rivet. No pictures of that, but we got it installed.

RV14 Build July 20

Aft Fuselage

It was well over 100 degrees today in the shop but I have some amazing friends who came over and helped me rivet on the upper side and top skins on the Aft Fuselage! Im so glad I had there help to get this done, now I "Should" be able to finish this kit on my own as far as reaching all the parts goes!

Just A lot of awkward movements to get the bucking bar on the rivet heads but nothing too crazy!

I put a bunch of old boxes down to lay on so I wouldn't stab my back or hit the airframe.

Just need to get my parts in to remove the aft bottom skin and bulkhead rivet that all together and this sections will be all but done!

Aft Fuselage and Elevator Mistake fixing July 15

RV14 Build July 15

Aft Fuselage

I received the new tools that I was waiting on to try and fix my mistakes on the elevator and the aft fuselage. The title mistake fixing is a bit of a misnomer, attempted mistake fixing might be better.

I started right in with the middle tool the 1/8 close quarter dimple die from Cleveland tools. They didn't work for what i was trying to do. This Aft Fuselage skin in thick and the pul rivet style of the dimple broke the shaft before setting the dimple. Then I thought why don't I drill it to size and place the dies around the hole and shoot and buck them like a rivet. This worked really well to make dimples!! The problem was I didn't clean up the holes well enough and upon inspection they were cracked in the dimple. I decide to drill out the whole bottom aft skin and reorder it as well as the bulkhead because those dimples cracked too. Lesson here...DEBURR better.

Cracks in the bulkhead dimple

I thought about reusing the Horizontal Stab attaching bars, but they were only $11 so I ordered new ones to match drill and assemble the bulkhead together.  Ill save these as spare metal/Parts.

On the left side lower stiffener my rivet drilling, which caused this can of worms in the first place, bit me again. So I ordered that as well. I think Im going to trim the stiffener and make a double and rivet it onto of the other instead of risking more damage by drilling out the stiffener the rest of the length.

The end result....Moving backwards today.

Elevators

The dimple die for the holes in the elevator trim motor access panel worked great! Finally a victory today. All i need to do is put the pins on the wires and into the molex connector and the elevators will be done!

Just kidding, I didn't know how to use the crimper and messed up the pins, new ones on order.

All in today cost my 4.5 hours and $120 in new parts. So much learning, this is what Im calling mistakes now....I need a beer.

RV14 Build July 12 &13

Aft Fuselage

Spent maybe 30 mins riveting together the Elevator Trim tab motor bracket, but the rest was all on the aft Fuselage. Mostly installing the rest of the systems and cables and riveting on the side skins. Im still waiting on the tools to do close quarter dimpling to fix the elevator trim motor mounting #27 holes I forgot to dimple and the #30 holes that Im going to match drill to enlarge in the second to last bulkhead since my sloppy drilling of rivets oblonged the holes.

 Trim motor bracket mounting plate.

Aft Fuselage systems installed!

 Static Lines

Rudder cables and cable guides

Cleaning, etching, and priming the last parts of this kit!!

Last wipe down with rubbing alcohol before spraying!

Time to install some of these skins! I jumped ahead in the plans a little. I can't install the aft deck until i fix the holes for the second to last bulkhead and reinstall that. My buddy Matt has been coming over to work with me while he sits on call, I can't tall you how nice it is to have a helping hand!!! Thank you Matt!

1 top side skin riveted on 1 to go!

Side skins are coming on nicely, just have to rivet the second top side skin, top skin, and finish the Aft deck area!

This thing is really looking like an airplane!
