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.
