Fuselage Final Assembly

Howdy everyone. I have my -7 fuselage upside down as per the instructions while I finish up the last few pages prior to disassembly for the usual de-burring, edge finish, dimpling, etc. Has anyone reassembled and riveted the fuselage right side up? Any reason not to do so?

I don't know how a guy would get it all clecoed back together like that. Plus when it's upside down on some sawhorses it is easy for someone to buck from the inside. It would be much more difficult to do it right side up.

Upside down

When it is upside down, all the saw horses are at the same height since they sit on the longerons.
