Started riveting the bottom skins

The rest of my avionics order showed up this morning. I also received the GMU 22 mounting kit from Van’s. Apparently they don’t make one for the GMU 11 (which is what I bought). So I took a chance and ordered the one for the GMU 22 thinking I could cannibalize it and create something for the GMU 11. As it turns out, all I needed to do was to match drill four holes to the base of the GMU 11. So I drilled the holes, cut the top half of the mount per the plans, deburred and primed everything, riveted it together, and screwed on the GMU 11. Bayum!

Remy helped me rivet the inboard bottom skin to the right wing. It was challenging to reach the rivets along the aft spar. Remy and I took turns bucking and shooting. Nonetheless, tomorrow will definitely be an Advil day.  I clecoed the outboard skin in place. That can be tomorrow’s challenge.

Fitted the aileron trim and inboard bottom skins

I finished inventorying and stowing parts from the fuselage kit and avionics.

Crimped the pins onto the aileron trim wires, added a heat shrink tube, and inserted them into the molex connector.

I centered the set the aileron trim using a 9-volt battery to drive the servo. I set the  assembly in place on the wing and set the aileron to the neutral position. Then I marked the point where the aileron trim arm rested over the  push tube. I remove the push tube and located the tabs 6 inches either side of the center mark. I match drilled and blind riveted them to the push tube. I attached the springs to the tabs.

 

I clecoed the inboard bottom skins in place on the wings. Ready to rivet.

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.

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.

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

Disassembled everything.

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.

Riveted right outboard leading edge skins to ribs

Riveted right outboard leading edge skins to ribs with some help from Remy.

Placed the leading edge back into the cradle and clecoed the J channel stiffener and the landing light bracket in place. I’ll rivet those in place tomorrow. It was getting late.

Sophie deburred the edges of all the tank ribs for me while I was in Toronto this week.

Finished dimpling everything

Clecoed the left leading skin to the ribs.

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.

Dimpled the rest of the parts.

Everything is ready for priming and assembly.
