From Microns to Megastructures: Machining at the Extreme Ends of the Spectrum, 472

What do a luxury wristwatch and a 50-foot-long aerospace weldment have in common? They're both precision-machined, but that's where the similarities end.  In this episode of MakingChips, we're exploring the extremes of manufacturing—from parts that fit on the tip of your finger to parts so massive they require cranes and riggers just to load onto a machine. Paul Van Metre and Mike Payne are joined by two guests who represent the far ends of the machining scale. Josh Hacko, a fourth-generation watchmaker from Sydney, Australia, crafts ultra-small and ultra-precise components for timepieces and high-tech applications like quantum computing and medical implants.  On the other end, Jerry from Baker Industries in Michigan oversees the fabrication and machining of massive weldments and structural components for aerospace, defense, and nuclear energy—some measuring over 50 feet and weighing tens of tons. This episode dives deep into the radically different strategies each shop uses for tooling, fixturing, inspection, quoting, and problem-solving. From tea strainers used to sort microscopic parts to massive additive weld builds handled by 30-ton cranes, it's a fascinating look at how scale transforms every aspect of the job. If you've ever wondered how much machining can vary across the industry, this conversation will expand your view. Whether you're cutting parts measured in microns or managing five-ton setups, one thing remains constant: it's all about having the right people who love the craft.
