Clearly I need to be more realistic about just how much I can accomplish in one day. I work all day, but I guess I'm a methodical (plodding) worker. I didn't get to the subflooring today, but I'm happy with the progress I made this week.
I started the day with the boards cut for the east end (bedroom) bumpout.
I cut notches in the boards so they cantilever out over the east end sill.
Then, I chiseled the inner end of each joist to flush fit a joist hanger.
I connected the joist hangers, more braces, and some toe-screws to hold everything in place.
I attached a board across the ends of the cantilevered boards. Not sure what that board is called.
Finally, I installed blocks between the cantilevered boards along the east end. Done! Isn't it beauteous? It seems a shame to cover all this work with subflooring so that no one can ever see it. Dale suggests a plexiglas floor, but that's not exactly what I had in mind. :-)
