"This grinder was operational in the shop as long as I can remember as a little kid, and the sound of the flat belt slapping when it was running is very distinctive. It still works, [although it] turns fairly slow. The sound of it really moves me back in time. [It's] almost eerie the way that sound also conjures up sights and smells from back then. Shut your eyes with it running and it's like a kind of time machine, really."
