Western Revolver Replicas, Arc Trainers, Used-Oil Furnaces, Vegetable Peelers and Pizza Cutters

How It's Made – Season 14

Metal components are cast, machined and finished to create non-firing replicas of historic Western revolvers. The episode also reveals how elliptical arc trainers combine steel frames with resistance mechanisms, how furnaces convert used lubricating oil into heat, and how sharpened stainless-steel parts become vegetable peelers and rolling pizza cutters.
