A Sturdy Subfloor
Bill found a 1 1/8" thick tongue and groove plywood made by Georgia Pacific which will meet code to span the 35"on center gaps between Christian's old trunk/beams that support the dining room floor. These 1780's floor beams are oak tree trunks made flat on top and are in remarkably great shape. The old floor here wasn't, so I located these (rare here) sub-floor boards from a left-over lot in PA since we just need nine of them. Each 4' X 8' board made in Oregon weighs 99 lbs., and they ship free to a NJ branch and then here in four days.
The earlier image above shows the tree trunk beams best, which had bark still in some spots while all were inches away from solid clay ground.
