Why I've Spent 25 Years Walking Factory Floors Around the World
From a CNC lathe in Ontario to 500+ factories across 40 countries — the origin story of how a kid who needed a job became obsessed with manufacturing.
Key Takeaway
From a CNC lathe in Ontario to 500+ factories across 40 countries — the origin story of how a kid who needed a job became obsessed with manufacturing.
I didn’t plan on a career in manufacturing. Nobody does. You don’t sit in a career counselor’s office at seventeen and say, “I want to spend my life smelling coolant and listening to spindles.” It just happens. A door opens, you walk through it, and twenty-five years later you realize it was the best door you ever found.
Mine opened in Ontario. I was young, broke, and looking for anything that paid. Somebody at a shop needed a body to load parts. I showed up. The foreman — a guy named Ron who’d been running lathes since before I was born — took one look at me and said, “You’re going to learn how to program this thing.” He pointed at a CNC lathe that was older than both of us. I didn’t argue.
The First Cut
Within six months, I was hooked. There’s something about manufacturing that grabs you and doesn’t let go. Maybe it’s the immediacy of it — you write a program, hit cycle start, and within minutes you either have a perfect part or a very expensive mistake. There’s no hiding. No “let’s circle back on this.” The part is right or it isn’t.
Ron taught me the fundamentals, but the shop floor taught me everything else. I learned that the best machinists don’t just know G-code — they know metal. They can hear when a tool is going dull before the surface finish shows it. They can look at a chip and tell you if your feed rate is off. That kind of knowledge doesn’t come from a textbook. It comes from years of standing next to a machine, paying attention, and occasionally screwing up badly enough that you never forget the lesson.
Going Beyond the Shop
After a few years of running machines, I started wondering what things looked like in other shops. Were they doing things the same way we were? Better? Worse? I started visiting other facilities — first locally, then across Canada, then the U.S. Each shop I walked into showed me something I hadn’t seen before.
A five-person job shop in rural Ontario taught me more about lean manufacturing than any consultant ever did. They had to be lean — they couldn’t afford not to be. A Tier 1 aerospace shop in Montreal showed me what happens when quality isn’t just a department but a culture. A tooling company in Michigan showed me that the best salespeople in manufacturing aren’t salespeople at all — they’re machinists who happen to understand their customers’ problems.
That’s when the visits stopped being casual and started being intentional. I wanted to see how the best shops in the world operated. Not from a conference stage or a case study — from the floor.
The World Opens Up
The first time I visited a factory outside North America was in Germany. A precision grinding shop in the Black Forest that had been family-owned for four generations. The tolerances they were holding, the condition of their equipment, the pride in their work — it reset my expectations for what manufacturing could look like.
From there, it snowballed. Switzerland, where I watched a watchmaker assemble a movement with tools I couldn’t even name. Mexico, where shops in Querétaro are producing aerospace parts that compete with anything coming out of the American Midwest. Japan, where the concept of continuous improvement isn’t a buzzword on a poster — it’s the air they breathe.
Forty countries later, I’ve walked through more than 500 factories. CNC job shops, die-casting plants, Swiss-type screw machine operations, injection molding facilities, sheet metal fabrication houses, and everything in between. Each one taught me something.
What You Learn After 500 Factories
Here’s what 25 years on shop floors around the world has taught me:
The best shops are obsessed with process, not equipment. I’ve seen $50K machines outperform $500K machines because the operator understood the process and the shop had systems in place. A new machine doesn’t fix a broken process — it just makes the broken process faster.
Culture beats strategy every time. You can tell within five minutes of walking a factory floor whether the company is healthy. Look at the floors. Look at the tooling organization. Listen to how the foreman talks to the operators. Watch whether people look up when a visitor walks by. A shop with a good culture will outperform a shop with better equipment and worse culture, every single time.
Small shops are the backbone of manufacturing. The world runs on shops with 10-50 employees. They’re the ones making the parts that the big OEMs can’t or won’t make. They’re the ones innovating at the process level, figuring out how to hold a tolerance that the textbook says is impossible. I’ve met more genius in small shops than in any corporate R&D lab.
Manufacturing is a global community, not a competition. A machinist in Querétaro has more in common with a machinist in Stuttgart than either of them has with someone in their own city who works in a different industry. We share the same problems, the same pride, and the same frustration when a tool breaks at 4:47 PM on a Friday.
Why I Keep Going
People ask me why I still do this. I’m not twenty-two anymore. I don’t need to be on a plane every week. The honest answer? I’m still learning.
Last month I walked a factory in Switzerland where they’re using AI-driven tool path optimization that cut cycle times by 30%. The month before that, I was in a shop in Texas where a 28-year-old is running a business his grandfather started, and he’s doing things the old man never dreamed of. Next month I’ll be at a trade show where I’ll meet someone who’s solving a problem I didn’t even know existed.
That’s why manufacturing keeps pulling me back. It’s never finished. There’s always another shop floor to walk, another process to understand, another person to learn from.
The Mission
Everything I do now — the podcast, the videos, the factory tours, this blog — exists because I believe the stories of manufacturing deserve to be told. The people who make things don’t get enough airtime. The machinist who figured out how to hold a micron on a part that everyone said couldn’t be made. The shop owner who mortgaged her house to buy a machine and turned it into a $10 million business. The apprentice who decided that making things with their hands was more rewarding than sitting behind a desk.
These are the stories I tell. Twenty-five years in, and I’m just getting started.
