Finally,
I'm down to the last wall! It's a simple 8' section running from
the screen wall to the support pole on the left. Since I carefully
planned the location of the support pole to blend in with the
end of the wall (and snapped the chalk line) that part was done.
However since the wall runs between the two main ducts and next
to the main support beam, I wasn't sure if I'd be able to build
it and tip it into place (using method 1 of framing
a wall).
Previously,
I had test-fitted a short one-foot section I had built for the
office closet (see framing the
office). It seemed there was enough space at the time, so
I built the wall first and then slid it between the ducts to stand
it up straight. It fit perfectly! I secured the top and bottom
plates, and that was that! (Well, almost!).
Because of the location of the three walls (office, screen, and
wall to the support pole), I was left with an awkward corner.
Rather than leaving three short (3-6 inch) sections that I'd have
to fit with drywall, I figured it would be better to close it
off and make a nice even corner. It took about ½ hour to cut and
fit the pieces, but FINALLY the FRAMING IS COMPLETE!
