This may be hard to explain, but here goes. I want to install a ledger board on a flat interior house wall (in a 2-story room), from which I plan to hang 2x10 joists (that will run 12' over to another wall). Installing the ledger would be no problem, except that there's a tall window at the end of my run. And, I want the ledger board to end in the middle of where the window is currently located. I will, at some point, be removing this window and replacing it with vertical studs, but I want to put this off until later, mainly because I plan to do the interior work during the winter. So, what I'm thinking is that I will let the ledger board extend beyond the window (i.e. span it), and then cut the protruding section (maybe 18") of the ledger board off later after I have installed studs where the window is now. OK...so my question is, how would I attach the ledger board to the vertical studs at the point in time where I have access only to the outside (the side facing the studs) of the ledger board? I understand that I could nail or screw from the outside into the ledger board, but then I'm relying on the shaft of the nail or screw to hold up the weight of the floor. I also though of installing something (a bracket?, a bolt?) on the ledger board while I have access to the other side, which will attach to the studs when they're in place. Any ideas, suggestions? Thanks!
