A little drilling, a little dimpling, a little riveting.

Reassembled the nose skin and match drilled the remaining #40 holes form the skin into the the counterbalance tubes. Then upsized them to #30.

Dimpled the skins for the stiffeners and ribs.

img_2762

Started back riveting the stiffeners to the skins. After riveting the first one I realized that I neglected to trim them to the correct length. It was obvious that they would interfere with the trailing edge extrusion. I’m guessing that the stiffeners are another shared part with the RV-10 thus requiring shortening for the RV-14.

I was able to trim the one I riveted with a cutoff wheel on the Dremel by sliding a thin piece of scrap aluminum under the stiffener to protect the skin. I deburred it with sandpaper. No harm No foul. I trimmed the rest on the bandsaw and deburred on the ScotchBrite wheel.

Had to quit to go watch the Bruins in game 7 of the Stanley Cup Final.

Fitting the flaps together

Assembled the inboard and outboard rod end ribs. Clecoed the ribs and doubles together. Match drilled the #40 holes and final drilled the 1/4″ hole. Countersunk the #40 holes on the outboard doublers.

 

Clecoed the ribs to the flap hinges and final drilled all the #30 holes.

Modified all the main ribs by removing the top forward tab from each with the Dremel and a cutoff wheel. Finished with a bit of sanding to remove the burrs.

Assembled the flap substructures.

IMG_2684

 

Trimmed the inboard and outboard trailing edges to final size with the bandsaw and finished on the scotch brite wheel.

 

Clecoed the flaps together.

 

Match drilled the two top holes in each of the nose ribs. I also final drilled all of the holes in the trailing edges.

img_2693

 

Assembled the hardware in the hinge to hold everything in alignment and match drilled the four holes in the  trailing edge of the hinge.

img_2692

Disassembled everything.

img_2694

Next I need to machine countersink the holes in the trailing edge wedge and the holes I just drilled in the hinges. Then dimple and prime everything.

Work resumes on the tanks

I received the J-Channel that that I ordered from Van’s. I cut it to length with a cut-off wheel in the Dremel. Then cleaned up the edges on the Scotchbrite wheel. I measured and marked the centerline. Drilled the starter hole. Clecoed it in place and match drilled the rest of the holes, clecoing as I went.

 

I clecoed the baffle in place and machine countersunk the corresponding rivet holes in the tank skin.

 

I disassembled everything final drilled the #19 holes in the skin and then deburred them as well as the holes in the j-channel. I dimpled the J-channel with the pneumatic squeezer.

In other news… My propeller was delivered! It’ll be a while before I need it but ordered it at the same time as the engine to get a discount. The engine has a much longer lead time. Expecting it to show up mid October.

Installed landing lights and lenses

Cut the plexiglass lens to 3/4″ larger than the opening in the wing using the Dremel with a diamond dust blade. Cut like buttah.

img_2618

Covered the lens with tape to protect it. Put in in place within the wing and traced the opening onto the tape. I lined up the backing places and marked the tape with the finished cut lines. I cut to final size with the Dremel and sanded the edges smooth with a sanding drum in the drill press.

img_2619

Set the lens into place and used the tape “leash” i made on the front of the lens to pull it tight against the inside of the skin. Drilled and clecoed all th holes with a #30 plexi bit.

img_2620

Remove the lens from the wing and removed the tape. I countersunk the holes with 100 degree zero-flute countersink bit in the electric drill. I deburred the back side of the holes with a single turn of the same bit.

img_2621

I used VHB double stick tape to secure the backing plates to the lens.

img_2622

I installed the landing light onto the bracket that I had riveted into the wing in an earlier step.

img_2624

I secured the lens in place with #6 stainless screws.

img_2627

And then repeated the whole process for the right wing.

This completes section 17–Outboard leading edges!

Finished dimpling everything

Clecoed the left leading skin to the ribs.

img_2492

Slid the j channel into place and clecoed the starter hole. Then match drilled all the holes from the skin into the stiffener.

Match drilled the aft-most top and bottom holes in each of the ribs.

img_2497

Disassembled everything and repeated the whole process for the right wing. Deburred and dimpled all the holes.

Dressed the edges of the skin with a file and sand paper.  The cut-outs for the landing lights were pretty jagged. I cleaned them up with an abrasive drum on the Dremel and some sandpaper.

Dimpled the skins with the DRDT2 and scuffed the insides with a scotch brite pad.

img_2505

Dimpled the rest of the parts.

Everything is ready for priming and assembly.

Much progress on rear spar

Screen Shot 2019-05-27 at 10.16.11 AM

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.

img_2299

img_2304

 

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.

Started the wing build

Screen Shot 2019-05-27 at 10.10.58 AM

Cut the J channel to the specified lengths with the Dremel tool and a cutoff wheel.

img_2196

Clamped the J channel to flange leaving it 1/16″ proud of the flange.

img_2197

Drilled and clecoed the J channel.

img_2198img_2199

Flipped the lower J channel to the upper flange to finish the holes where the nut plates were on the lower flange. I marked the J channel and set aside for later when the skins go on.
