Part 2/10:
The speaker begins by describing a recent activity—playing with a metal-shaping machine, specifically a seven-and-a-half-inch stroke model. They detail cleaning techniques involving cosmoline, a preservative used during shipping to prevent rust, which they mention comes off easily with some effort. The heavy grease and oil covering the machines require careful cleaning; the speaker emphasizes that old cosmoline, oil, and grease tend to turn dark and brittle over the years, but with patience, they can be removed to reveal the machine’s condition.
