Mechanic’s Tools and Chainsaw

MECHANIC’S TOOLS: The key to winning a NASCAR race is a lightning-fast pit stop. And for that, hi-tech mechanic tools are crucial: the hydraulic jack, impact wrench, and a good set of socket wrenches. We’ll clock the evolution of these tools and more and reveal the secret weapons of racing, including 1,000-piece socket sets, sawzalls that can rip apart metal, and a special tape that can hold body parts on a racecar at 200 mph!
CHAINSAW: Invented specifically for the logging industry, the chainsaw began life as a half-ton behemoth in 1905, was refined to a portable 2-man tool in 1929, and finally became a single-user powerhouse in the 1950s. We visit a modern chainsaw factory, where today’s technologically advanced machines are manufactured on massive scale. And we look to the future of the chainsaw–the Timco 820, which can harvest seven acres of trees in a single day.
