Category: Wing Ribs (Section 14)

Wing ribs complete

Riveted the forward flanges of all the ribs to the spar with the rivet gun. My riveting seems to be getting better… Didn’t have to drill any out. I set the pressure at the compressor to 75psi for the -4 rivets. This seemed to work really well. I had tried a lower pressure in the past and the manufactured head would get all beat up. At the lower pressure, I had to hit the rivet so many times that I think it was getting work hardened.

I also finished installing the AN3 hardware and torquing to spec. Kinda sorta starting to look like wings…img_2291

 

Picked all the parts (including the service bulletin kit) for the rear spar.img_2293

 

Today’s Time (hours): 2.0
Wing Time (hours): 54.5
Total Time (hours): 265.5

Primed everything and started assembly

 

Wiped everything down with acetone and then shot primer. I did the spars first, then the ribs in two batches, and finally all the other small parts.

 

 

Riveted the flap hinges and hinge ribs to the ribs. I started using the squeezer but it couldn’t reach most of the rivets so just switched to the gun and shot the rest of them.

 

 

Assembled and riveted the the torque tube brackets and riveted them to the inboard ribs.

 

 

Clecoed the ribs to the spars and reinstalled the AN3 hardware and torqued everything down. I also installed the snap bushing in the systems holes in all the ribs. Many of them were a bit loose. I’ll have to give some thought on how I want to resolve this.

Final drilled ribs to spars and drilled systems holes.

Spent a lot of time finishing the deburring of all the holes in the flanges and finishing dimpling the lower flanges of the ribs.

Clecoed the ribs to the spars and final drilled all the holes in the forward flanges.

Disassembled everything  and deburred the rest of the holes.

Measured, marked, and drilled the systems holes with the step drill.

Deburred all the the systems holes.

Ready to prime and assemble ribs.

More rib work

I set the spars on the work benches opposite one another and removed all the bolts.

It went a lot quicker when I remembered I had an impact driver in the tool box.

There are a whole bunch of bolts in the spars.

Work on the ribs continues

Netflix and scuff! Sophie deburred and scuffed all the ribs while I was traveling this week. Awesome job!

I fluted and straightened all the ribs.

I assembled and final drilled #30 the torque tube bracket assemblies.

I clecoed the torque tube bracket assemblies to the inboard-most ribs and final drilled them to the rib webs.

I clecoed the flap brackets and flap bracket ribs to the inboard and outboard wing ribs and natch drilled all the #30 holes.
