(Above: It was a trial to make the utility hole larger for this beast’s hoses, but from the small test I ran, it was well worth the effort.)
Building Summary: Morning activities entailed my beginning to put up the pocket door frame and moving Madre’s future container office onto the second set of pylons with Padre (and straightening the edifice as well)*. This was followed by my transporting the portable A/C down to the farm, dropping it off, and then going to Sparr with Padre to procure some supplies (water hoses for the shower fittings, mildew resistant caulking, and rivets for putting up the soffit).
Afternoon activities consisted solely of setting up the portable A/C. This included: cutting the utility hole even larger to accommodate both the intake and exhaust hoses, unboxing the appliance, attaching the hoses and hose fittings, and then extending those hoses through the utility hole to outside.
Commentary: This afternoon, the inside of Jacobhouse was upward of 90 degrees Fahrenheit. I wanted to finish the pocket door frame, but I just couldn’t do it. Not with the air-conditioner – or rather, its box – just staring at me! So, I tended to that instead. Little did I know the following process would include cutting the utility hole larger.
True, I could have merely set up the window adapter, but I knew that was not the permanent answer to my problem. (And since when has delaying the inevitable been a positive course of action?) No. I deigned that I wanted to set up that new Air Condition this afternoon, and I wanted to set it up right. So, despite the tight quarters of where I was cutting, the sweat pouring from my brow, the >¼” thick metal, and the sawzall blade slipping out of the machine no less than four times, I cut that hole and set up the A/C unit in all of its dual-hosed glory.
Never, has a blast of frigid air felt so pleasant as it did after all that shenaniganry.
Before: The pencil marks indicate where the hole needed to extend. 
After: The top hose is the intake, and the bottom hose is the exhaust.
Final Note: Tomorrow I will finish putting up the pocket door frame, and then I will either work on the behind-shower piping or the ‘plywooding’ of the bathroom’s interior.
*As can be seen by the GIF in my Twitter feed, there were some comical points, but the container lifting process went quite smoothly and took no more than half an hour.
