Well Folks, the weather and my job (considered as "essential personnel" and "mission critical" during this Covid issue) has put this on the back burner the past couple of days. The time at work has given me a few ideas to do the shaping. I will get back to it when I get off of work tonight. I did have to move this project into the house and on the dining room table......at some point, I need to build a garage. Driveways + rain, snow, bugs at night with a bright light get old after awhile doing stuff like this.
I had looked into building one out of aluminum, but without some sort of access to an English Wheel, I wasn't sure how to make the corners smooth out like being able to do with the foam.......and I wanted something that is all one piece and not have seams with rivets sitting that high up.
One other thing I have noticed with the Armstrong A/C. On the top of the compressor is the overload relay. If that gets too, hot as if the compressor has overheated, it shuts of the compressor. On mine, if it has been sitting in direct sunlight (still has the galvanized cover on it) and is already hot, it cuts off the compressor. I am guessing the fiberglass wont absorb as much heat and transfer it down to the overload switch as aluminum sitting on top of metal. I'm not an engineer and don't know the specifics of metallurgy and heat transfer, but this is just something I have noticed.
I will post more on the progress soon!
