Roll Bar Attachment and Rear Bulkheads

 
Today I took Tim, Cameron and Kaleb to the shop and we worked on the airplane.  The boys pulled the rivets on the roll bar assembly.  While they worked on the roll bar I removed the vertical stabilizer from the tailcone.  The vertical stab needs to be removed before I attach the tailcone to the fuselage so this is a good time to get that out of the way.
 
After the roll bar was riveted we temporarily bolted the roll bar bases to the fuselage at the attachment plates.
We then slipped the roll bar over the attachment bases and clecoed it in place along with the roll bar brace supports.
 
We matched drilled the bases to the holes in the sides of the roll bar.  We then tipped the fuselage on its side and drilled the holes on the inside of the roll bar to the bases.
 
After match drilling the bases we removed all of the clecoes and removed the roll bar, braces and attachment plates and deburred the parts.  They are now ready to be primed and painted the final interior color, which I am planning to be a light tan.  We then prepared the rear bulkheads to be clecoed into the tailcone so the small attachment brackets can be match drilled to the rear bulkheads.  
 
We match drilled the holes in the brackets and now the tailcone is ready to be installed on the rear of the fuselage when I arrive at that step.
