After having carried a 10x10 Fotar up a good flight of stairs and installing it all by myself, I'll offer my views...
Take the weights out of the column or it will be too unwieldy to handle.
Do not assemble the whole unit before the colum is mounted to the wall as it says in the instructions. It may be simpler to slide the modules onto the column but it will take two or three people to do that. Mounting the colum first and then assembling the head, stage and table can be a one person job.
If you mount the column first, you can easily remove the bearing plate holders for the table, etc, then tilt it into place on the rails. Support it with something strong underneath while you re-attach the bearing plates. If you do the table first, eveything else can be rested on the table on up while reassembling. Place the weights back inside the column and put something under them to hold them up a foot or two from the floor so the cabling can be re-attached.
You'll only need a few large allen keys and a set of wrenches to assemble. Disassembly may depend on how it's mounted now?
The concise assembly instructions and diagrams are available at
http://www.southbristolviews.com under Graflex Manuals. It also shows the all important cabling and suggested mounting techniques.
The whole thing is really pretty simple, but heavy. The column was the most difficult as it's long and cumbersome. Everything else was just heavy. Putting it all together takes time but it's not difficult... Oh, and I mounted mine about nine inches from the wall specifically so I had access to the weights and cables for my re-assembly style...
