For the attic space to be usable it needed flooring, so this was my next project in the old house, initially started in the winter of 1985.  What you see in the picture is an old beat-up oriental rug over new plywood I had put down in the main center area. When pulling up the old rotten flooring in the center area of the attic, the old original 1920s "tube and knob" electrical wiring that still remained in most of the rooms was found in several main floor ceiling areas to be bare wire that turned red hot when lights were turned on.  I found charred sections of attic flooring and first floor ceiling joists below them burnt. This spurred a year long project to rip out all the old wiring and replace it with new.  While doing some of wiring work in the basement, I decided to replace all the old corroded steel plumbing with copper pipe as well adding another 3 months to the project.  I took several months off work in the spring of 1986 after certifying the Flight Management System on the Boeing 737-300 aircraft.  This was time I used to get the majority of all this work completed.  I didn't take any pictures of all the electrical wiring and plumbing work. I pulling wiring and plumbing to the attic area in anticipation of one day finishing the attic.
