Fixed the right aileron hinge and riveted to rear spar

Did some flying with Jared today in his RV-14A. Awesome day dancing around some scattered clouds and some fun aerobatics. Thanks for the great flight today, Jared! The aerobatic training is definitely paying off. Sorry no pics. I was having too much fun!

Meanwhile back at the airplane factory…

Received the replacement parts from vans and did the little bit of fabrication necessary to prepare the doublers and attach brackets.

Deburred and primed the new parts with SEM rattle can primer. Riveted the attach brackets to the hinge.

Riveted the hinge and doublers to the right rear spar.

The mistake cost me $45 in parts and an hour and a half of build time.

Got my new 3/8″ reamer from McMaster Carr. Used it in the drill press to precisely size the rear spar attach holes. The twisted flutes cut like butter.

Clecoed the rear spars to the wing ribs. Ready to rivet tomorrow.

Much progress on rear spar

Peeled the vinyl from all the parts. Did the minor cutting and fabrication called out in the plans. Cleaned up and deburred all the edges with file, deburring tool, scotch brite wheel, and sandpaper. Scuffed everything with a scotch brite pad.

Assembled and final drilled the aileron hinges. The inboard hinges are from the service bulletin. I’m surprised they haven’t updated the plans yet. Had to follow the SB instructions.

Clamped the spar doublers to the spars and match drilled them.

 

Drilled out the aileron pushrod hole in the inboard doublers and cleaned them up with the Dremel.

 

Clecoed the right rear spar together with the wing assembly.

Fabricated the HS Attach Support and Rudder Stops

I cut the horizontal stabilizer attach bar support angle from the provided aluminum angle. I measured it out with the calipers, marked it. Drilled stop holes in the inside corners and used the bandsaw to remove most of the material. I finished removing material with a vixen file and cleaned it up on the scotch brite wheel.

Made the rudder stops from the provided aluminum angle. I measured with calipers, marked up the angle and cut it on the band saw. I cleaned it up with a file and the scotch brite wheel.

IMG_1870

I machine countersunk the top two holes in each rudder stop. I was totally stumped on how to countersink the other two holes on the inside of the angle. The countersink cage won’t fit. After some head-scratching I gave Jared a call to see what he did.

IMG_1872

Apparently theres a thing called a “paint cutter arbor” that has the same threading as the countersink cage and one can mount the countersink cutter into it and mount it in the drill press. So I ordered one from Aircraft Spruce.

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.

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.

So F’ing Close!

I thought for sure I would finish the elevators today. But no! Came up short by five AD-41-ABS pop rivets.

IMG_1847

Started the day by riveting the trailing edges. I lightly set all the rivets with the pneumatic squeezer first. Then propped everything up so that the trailing edge rested flush to the back rivet place and very carefully used a mushroom set on the bottom to finish the double flush rivets. With he “backward” trailing edge of the elevators, I almost needed to use just the edge of the rivet set. It was tricky but I’m happy with the result.

Remy helped me roll and rivet the leading edges.

IMG_1844IMG_1845

I cut and installed the lead counterweights. Is it me or does installing lead in an airplane just seem wrong? 🙂

IMG_1846

And here they are. My almost completed elevators!

TODO:

  1. Finish riveting the leading edge (ordering rivets today)
  2. Terminate the wires from the (waiting for crimper to arrive)
  3. safety wire trim tab hinge pin (waiting for safety wire to arrive)

New Trailing Edge and Skin Prep

I got home from a grocery run with the family and my replacement trailing edge was waiting in the driveway. Thank you, Van’s. Their shipping team is not taking any chances. The trailing edge was wrapped in paper, and sealed in a length of PVC pipe with PVC end caps. The end caps were sealed with that tape they use for packing everything. This is the stickiest tape ever. I’m thinking I might build a plane from it after the RV is done.

I was just going to bring it down to the shop. But once I saw the packing job, I just had to open it.  …and since I was down there and the drill press was still set up for countersinking trailing edge, I clecoed it to the skin, marked it, trimmed it, and finished the outboard end correctly this time. And then I countersunk it.

…and while I’m down here, I might as well prep the skins for bonding, too. Same drill as the trim tab… Measure, tape, strip primer with isopropyl, sand, and wipe with acetone.

Ready to start assembling the elevators!

Happy New Year!
