I got another second floor gable wall put up today.

It was very heavy, especially with the 4×12 window header installed. I still don’t have any wall jacks, but I did order some by mail. UPS is supposed to deliver them on Monday so I should be able to use them for the long walls next weekend. I expect to build the north wall tomorrow and lift it next weekend. It should be simple to frame and sheathe; there are no openings. Just full sheets of plywood and precut studs.
