Riviting the front and mid skins together presents some very challenging bucking situations. I made another custom bucking bar to get under the seat rail mounts. Its a good thing I have a lot of steel chunks in my scrap box.
After the join was complete the next steps installing the seat rail supports, control stick mounts and mid fuselage side plates. In fact until the side plates are on there is still a lot of flex in the assembly. I was tempted to turn the whole thing up on it's side for riveting and left of due to concerns of bending the bottom skins. I;ll come back later to finish the rivets in between the front center ribs. Too hard to reach without climbing right up on the fuselage.
