Completed riviting left spar ribs - 2.5 hours

I riveted the new rib onto the right spar as well as the few remaining ribs. I then cleco'd the rear spar on and managed to set a few rivets.

Prepped new W-711-L rib - 2 hours

The new W-711-L inboard rib for the right wing (Rib #3) arrived. I deburred the rib, drilled the wiring holes, straighten and flute. Then I washed and prepped, and primed. 

Completed riveting Left Wing Skeleton - 2.5 Hours

I riveted the rear spar to the left wing skeleton. Everything went pretty uneventful. I used the flush rivets in the end outboard rib. The rivets are set well, but the rib has a very slight distortion. It's perfectly fine as the material is tight around the rivet, but the outside edge of the rib flange wants to site just proud of the rear spar.


 I primed the flush rivets as the aileron hinge will eventually sit tight against it.

I can see why the instructions tell you to place the manufactured head on the thin material specifically for riveting the ribs to the spars. Of course I made sure that all manufactured heads where placed on the thinnest material. The end outboard rib is the only instance where you cannot do that.
It is important to double check the rivet callouts. I find that the Vans callout's tend to be off by 1/2 size. I'm sure that they are just fine for use, but I chose to set all according to the rivet gauge.

Every rivet was set extremely well, just had to drill out and replace one rivet. Sweet!

Fine tuning the wing-walk ribs (Left side) - 3 hours

Well I performed some surgery with some files on the offending rib #3. I cleaned up the edges with scotchbrite and spot primed the needed areas. I let it dry a few hours then I riveted the rib to the spar.
 
On rib #2 I quickly noticed that the rivet also interfered with the rib. 
 
 I also checked rib #1...yup. Slight trimming needed.   

More riveting wing ribs to wing spars - 5 hours

I hung up the right wing as it is on hold till I order a new W-711-L inboard rib. I decided to start the left side. I back riveted ribs #13 thru #10. Back riveting the ribs #9 thru #1 becomes tricky as you have to be very careful not to damage the top and bottom doublers. It was an incredible pain to try to avoid this on the Right wing that I decided to try something different. I set up blocks to help ensure I don't push the assembly off the table. I then set up a block with a clamp as a bucking bar rest.

I have a second person hold the bucking bar as I shoot the rivet. The rest work extremely well for someone that has no experience bucking rivets. It's very easy to ensure the bar is perpendicular to the work. The result is extremely well set shop heads.

I have to do this kind of setup more often!!  

Seems that I have a small interference on rib #3 left wing with one of the spar rivets. I have double checked that I have the correct rib and correct orientation. Might have to do some trimming. Thought I would post it on Vans Airforce and make sure I am correct before I start cutting.
