Alex, your father and uncle taught you well!
My dad started me out at that age or earlier, but I couldn't make a straight cut to save my life. He had no power tools, we did EVERYTHING with muscle power, sawing, drilling, even cutting up trees with a two-man crosscut saw. I have two cordless drills and a good hand power saw. I still can't make a straight cut!
Electrical is a different story, I worked 43 years in electrical/electronics.
Your photographs confirmed my idea for the around the wall benchwork is sound! Thank you!!!
