After we finished the rest of the rivets (which by the way were NOT easy, we decided to order cherry rivets for the aft most river between the skins and the bulkhead that resides just beneath the ridge of the lower longeron. Basically impossible to set it with a bucking bar and not sure what else to do, so we calculated the length of the appropriate cherry rivet and ordered it. It was CR3212-4-4 and it connects the lower longeron to the wing box. Then I added the seat rest bar which included 3 rivets that I do not rivet until after the next step when I insert the intercostals. Congrats Van's you got me again! Luckily I am an expert at removing rivets so this was a non-event. 🤫 After that I am supposed to do some work on the vents but they did not send me all the parts. In fact, I do not even see it on the inventory list. In fact, when I search the store I have never seen this part before in my life. I'm going to have to contact Van's and see what I am missing here. The missing part is VENT-SV5. So it's on to section 30! A short section but the holiest of all—joining the fuselage with the empanage. To prepare for this I removed all the tail feathers and stored them in safe places Ed around my house.
