It wasn’t painful, it was just a matter of putting in the remaining 20 2×6 boards that make up the second floor. Last April, I had started it, but ran out of time to finish it.

Now 3/4 of the floor is covered. The remaining 1/4 will stay open and allow a stairway. Now access is ladder only.

This pano also shows the work I will start on tomorrow;
stick framing the gable ends (where you see trees).
Much easier to do with a floor. My tent (you can see the blue top) will have to be moved, so I can place the scaffolding on the inside, to reach the right end of the gable end, although I might try set it up on the western deck, as after stick framing, OSB boards will need to go up and then siding boards.
I will start with the eastern gable end; the floor goes across the entire width there.
