The tail cone fuselage frames are constructed from left and right sections.
After finishing up with the deburring of all the
left and right fuselage frames, work began on fluting the frames which
basically, from what I’ve read online, less is more in this instance. I just
lightly fluted the one edge on each frame that has the long line of holes on the solid flange to get those holes all in alignment. Once the two halves are
riveted together, they may need some additional tweaking.
Once the frames were lightly fluted, work began
on the dimpling process for the flush rivets being used on the RV-12 project. All of the flanges on all the tail cone’s fuselage
frames were dimpled. There are four rivet holes on the top of the rear bulkhead
and four rivet holes on the top of the aft most fuselage frame that technically
don’t need to be dimpled because those locations will be hidden when the
vertical stabilizer is in place … I chose to dimple for consistency.

but did get some of the blue plastic film removed from them along the rivet
lines in preparation for lots of dimpling tomorrow.
