Oscar Lindberg spent forty years as a dental technician in Minneapolis, working under magnification on objects most people could barely see. When he retired, he wanted a hobby that used those same skills-and Z scale turned out to be the perfect fit. His detailed layouts prove that the smallest scale doesn't mean compromising on realism; his current Great Northern project fits in a space smaller than most people's desks but includes handlaid track and scratch-built structures. Oscar writes for modelers intrigued by Z scale but intimidated by its demands, sharing techniques for working at 1:220 without losing your eyesight or your patience. He admits the scale isn't for everyone, but for those with steady hands and good lighting, the possibilities are remarkable.
