Boy O Boy. That’s some equipment.
Amazing stuff. I have nothing but time on my hands and can spend the time to watch some of the stuff. There is a video of the construction of the worlds tallest bridge that boggles my mind. Railroads installed by a half dozen men, or mining machines that replace all the hand dug coal operations. Then for a change of pace I watch Mr. Chickadee who does amazing carpentry with absolutely no power tools.
