Riveting rudder ribs

3.0 hours

I didn't plan ahead and size the holes inside the rudder brace for the -4 blind rivets, so I needed to figure out how to get a bucking bar inside. I decided to make one out of some 1/4" steel bar I had. This worked out ok, though it's mass was kind of low

After getting the 8 rivets inside of the horn brace, did the rest of the rivets on the lower rib with the squeezer. The last 4 I will need another special bucking bar, as the squeezer won't fit

To get ready for riveting the trailing edge, I needed to glue the aex wedge and the skins together with fuel tank sealant. This is hel together with cleco's and an aluminum angle to hold the trailing edge straight.
