What a great Monday! We made excellent progress.
Brian designed the metal drip-caps for the north windows, purchased the supplies and began cutting them down to size. I arrived on the scene, congratulated him on his success, helped install one half of one drip-cap and then insisted that we get back to the inside of the house. He can work on the windows as a solo project so it makes sense to forge ahead with the wall work that requires both of us.
We unrolled a roll of insulation to determine how long it was (see featured image above). It looked as if we’d have a whole foot of excess which we felt was awesome. That means we will be able to create a great seal where the endcap wall meets the arched wall insulation. We held it up so that the bottom slid nicely between the underlayment edge and the metal base of the arched rib structure.
It took a few rounds of taping and sliding right and left, but we eventually got it nicely centered. Once on the wall, it turns out we only have about 2 inches of excess, so there is approximately an inch that will extend into the endcap walls.
We took our first 16′ 2×4, and using our Auto-Perforante screws (spanish for ‘self drilling’), installed it against the beams. The screws flew through the wood like butter and then required a little effort to get through the metal. It was especially difficult on the first 2×4 because it was near the ground, requiring a hunched posture and creating a disadvantageous leverage position.
Once the 16 footer was in place, we set up a work surface outside, in the pitch dark, and cut the next 2×4 down to 7′. We installed the 7′ piece and stood back to admire our work. Next up was the same thing, this time 4′ above the ground.
We plan to use 4×4 sheets of plywood as our wall coverings, so we spaced our 2×4 furring strips as 4′ on center (44.5″ apart). In order to get the next 16′ board against the wall and have it at the correct height, we decided to cut two pieces of wood that were 48″ minus 3.5″ (3.5″ is the width of a 2×4) long and use them as our spacers for each run. With a spacer atop of the bottom piece and holding up the next 2×4, I stood in the middle and pressed the 2×4 against the wall, doing my best to defy gravity until Brian got two Mega screws in. Now that we weren’t working close to the ground, we found the metal ribs to be slightly concave and had to graduate to auto-perforante screws that were bigger/longer to make it through. However, despite that mega screw being more difficult to shove through metal, the whole process was much easier because Brian could stand.
Wash, rinse, repeat. With the second board in place, we went back out to the darkness and cut another 7′ piece to finish that row. Considering it was 8:30pm by that point and that we were quite hungry, we called it a night. The progress is now tangible and exciting!
