Our contractor removed over 1000 board feet of 1940 vintage Southern Yellow Pine from the roof which was used as sheathing and the attic floor.
We made a decision to reuse the wood as the ceiling in the great room and the dining area.
Pat and I removed all of the nails and we planed it for the first time to about 1-inch in thickness. I am now in the process of planning to 7/8-inch and running the board through the table saw to size to 4-½, 5, 6, 7, 8 and 9-inch as appropriate.
