21-Day Machining of 3-Ton Industrial Gear Using 100-Year-Old Tech – A Must-Watch for Kiwi Engineers

Experience the jaw-dropping precision of old-school engineering as a massive 3-ton industrial gear is machined over 21 days using 100-year-old technology. This is more than just metalworking—it's a tribute to mechanical mastery that continues to inspire engineers and makers around the world, including right here in New Zealand.

In a country where innovation meets tradition, this video is a perfect watch for Kiwi engineers, machinists, apprentices, and industrial historians. Whether you're working in Taranaki’s heavy industry, a Canterbury workshop, or studying engineering in Wellington, you’ll appreciate the balance of endurance, precision, and timeless design on display.

This project also speaks to the values of sustainability and resourcefulness, as heritage machines prove their worth in the modern world—something many New Zealand manufacturers are revisiting in the era of circular economies and low-waste production.
