Lean Built: Manufacturing Freedom

Andrew shares a recent experiment in his shop: installing a full Sonos sound system and changing the structure of morning meetings and 3S time to give employees more room to pursue real improvements. Meanwhile, Jay discusses several new internal tools he has built, including an AI-powered quoting system and digital production boards designed to replace traditional analog shop boards. The conversation also includes the difference between Two Second Lean and traditional TPS-style lean, how AI is changing the speed of experimentation inside businesses, the hidden problems with too many meetings in manufacturing organizations, and what shop tours can teach you (and why you should never show up as a tourist.

A tornado tears through Bloomington, leading Andrew and Jay to discuss practical leadership during real-world emergencies. From there, the conversation shifts back to the shop floor: chip conveyors on Brother machines, production layout tradeoffs, palletized workholding vs. one-piece flow, and the realities of automation. They explore the pros and cons of high-density fixturing, robot-fed cells, and Okuma’s compact MU-600V five-axis machine with part handoff capability. The second half moves into the accelerating world of AI in manufacturing. Jay shares how he’s using Claude to rapidly build internal software tools, while Andrew talks through vibe-coded machine monitoring dashboards and real-time shop visibility systems. They wrestle with simplicity vs. data overload, operator-focused visual management, and what the next wave of AI-powered shop tools might look like.

In this special guest episode, Andrew sits down with Russell Watkins, co-founder of Sempai. Andrew first met Russell at the Gemba Summit in Belfast, where Russell delivered a keynote titled “10 Lightbulb Moments from Working with Toyota Japan and UK.” After cornering him at lunch with a notebook full of questions, Andrew knew this had to become a podcast conversation. They explore: This conversation bridges the gap between the Two Second Lean community and traditional Toyota Production System thinking, offering practical insight for small and mid-sized manufacturers who want to move beyond local optimization and align improvement with long-term business survival.

Jay and Andrew unpack a provocative quote from Shigeo Shingo: “If you don’t know why defects are occurring, make some defects.” It sounds like lean heresy at first. But they explore why some defects are treasures and others are just carelessness. The real question: are you reacting to problems under pressure or deliberately creating space to uncover them before they cost you? Along the way, they talk about a cantaloupe-sized rat’s nest choking a dust collector, moving machines and uncovering years of accumulated waste, the power (and danger) of acronyms in lean culture, and practical Fusion CAM workflows for maintaining standards across machines.

The way you treat people in business often matters more than the deal itself. Andrew and Jay talk about what happens when something breaks, an emergency hits, or you need a favor...and why companies that build goodwill get help while others get ignored. Drawing on real shop experience, customer behavior, game theory, and a Godfather analogy, they challenge the idea that business is a zero-sum game and argue that collaboration, trust, and shared wins quietly determine who survives and who doesn’t. Before that they catch up on what’s happening in their shops, covering recent machine work, air and power challenges, and small automation ideas to reduce wasted effort. They talk through using AI for internal software, quoting, and understanding business data; they also talk through websites, first-mover advantage, practical 3D printing workflows, and more.

What does a good lean elevator pitch sound like? Why do small, well-intentioned improvements end up causing problems later (hint: it helps to document things)? And how do owners listen closely to customers without losing sight of the long-term direction they’re trying to steer the business toward? In this episode of Lean Built, Jay and Andrew talk through those questions. Along the way, they discuss why intermittent problems are usually the result of stacked variables, not single root causes, why experience and judgment still matter even as systems and data improve, and much more.

Andrew and Jay walk through a situation a lot of shop owners have faced: a brutally tight print that can be machined but can’t be verified with confidence. At least not without the right metrology, systems, and alignment with the customer. Instead of rushing a quote or ghosting the RFQ, this is the kind of situation you have to handle like an owner. In other words, slow down, ask uncomfortable questions, protect the relationship, refuse to roll the dice on quality. Andrew and Jay dig into that and a lot more, from CMM alignment war stories to probing macros, SMED, automation vs. operator error, and why a shop full of green lights doesn’t always mean things are healthy. The thread running through all of it is simple: speed, precision, and profit are decided long before the spindle starts turning.

Jay and Andrew talk through everyday shop systems that seem simple until they aren’t: HVAC, shutdown routines, checklists, timers, and light automation. They compare notes on where “smart” solutions help and where they quietly create new problems, especially when reliability, safety, and human behavior matter more than elegance.

Andrew and Jay talk about why relationships matter a lot in business. Sometime more than products, systems, or raw talent. They dig into the practical value of local relationshipsfor staying informed and connected as decisions get made around you. From there, the conversation ranges across manufacturing, housing, leadership, parenting, and team dynamics. They also discuss when a product is finished enough to release, why over-tinkering stalls progress, and the role of people who know when to stop refining and move things forward. The episode closes with a clear-eyed look at AI in business: where it’s useful, where it falls short, and why responsibility still sits with the owner.

As 2026 begins, Andrew and Jay take a look at one of the most dangerous traps for founders and small shop owners: becoming the hero who always steps in to save the day. Andrew introduces a personal document he titled “Andrew Is Fired,” a deliberate decision to remove himself from roles that feel productive but quietly limit growth. The conversation explores why constantly “going above and beyond” can actually be a form of selfishness, how undocumented processes turn leaders into bottlenecks, why clarity around ownership matters more than raw effort, and more.

In this end-of-year episode, Jay and Andrew unpack all kinds of things: need

What happens when a rush job collides with holiday shipping chaos and failure isn’t an option? In this episode, Andrew walks us through a real-world manufacturing crisis involving last-minute customer demands, specialty tooling delays, weather-related shipping failures, and nonstop overtime. Along the way, Jay and Andrew cover: the true cost of rush orders (beyond the invoice), why duplication and redundancy matter in high-stakes work, when it makes sense to say yes and when it’s wiser to walk away, managing time and expectations, customer communication under stress, and more.

Jay and Andrew discuss real-world shop challenges like air quality, ventilation, coolant selection, and bandsaw blade performance. The conversation expands into capacity planning, why running at 100% utilization is a hidden liability, and how maintaining margin and flexibility allows shops to respond quickly when customers need help. Along the way, they touch on safety systems that fail when alerts are too distant from the problem, lessons from catastrophic industrial accidents, and why local, thoughtful gestures like good donuts or quality coffee build stronger vendor and customer relationships than generic (or just plain bad) corporate gifts.

Tiny improvements won’t move the company forward unless leaders also make the big decisions. Lean is life-changing, but you can’t lean your way into a clear vision. You have to choose it. That means looking honestly at customers, pricing, equipment, automation, space, and your team, and fixing what really bugs you at the highest level. That lesson is at the crux of this jam-packed episode which also covers: visual controls that save mental energy, smarter checklists that stop cultural drift, and a simple light-curtain jig that turns a tedious sewing task into an effortless one.

It's Cyber Monday, and Andrew and Jay dive into year-end strategy, the real cost of Black Friday sales, and why deep discounts often hurt more than they help. They also discuss how lean manufacturing practices literally saved an entire 60,000 sq ft facility after a major fire. Elsewhere, Andrew shares the importance of using LinkedIn with intention, how handwritten notes beat (or should be combined with) AI transcription for capturing insights, and why business owners must prioritize end-of-year tasks before the December panic hits. Jay breaks down inventory strategy, shop-floor safety improvements, and the hard truth about tax planning, CPAs, and executing (not just dreaming) your business vision.

Andrew opens with a simple shop-floor idea that changed how their teams celebrate progress: a six-inch clear tube filled with colored marbles. That playful visual turns into a deeper conversation between Jay and Andrew about the power of collective improvement, the limits of mental capacity as organizations grow, and the art of estimating through Fermi numbers. They move from marbles to antennas, from CNC stencils to parabolic reflectors, and from daily shop habits to long-term business planning. The episode also takes a serious turn as they take a blunt look at succession planning, wills, and preparing your company and family for emergencies. Jay adds insights from Pico La, including the lessons of shared leadership, clear org charts, and building resilient systems that survive beyond any one person.

When Jay asks what machine someone should buy to start a small job shop, Andrew gives a direct answer: without committed, repeatable work, he wouldn’t buy anything. But both Jay and Andrew do offer their recommendations, and that opens a broader conversation about the unstable economics of prototypes, customers who send sketches instead of CAD, and why certain jobs are better routed to services like Xometry or Upwork. From there, Jay and Andrew compare Haas and Brother machines—control systems, tool changers, rigidity, multi-axis capability, and real reliability differences. Andrew explains why he favors the Brother S700 for multi-sided work and describes the problems he’s seen with chain-style ATCs, including misloads that can send tools straight into the table. Around that, Andrew talks about his experience at Boombastic, the new generation of talent showing up there, and who else might benefit from attending.

In this episode, Andrew and Jay take a walk down memory lane. What starts as Andrew revisiting old shop photos turns into a conversation about the hidden value of reflection in a culture obsessed with constant improvement. The two discuss how looking back fuels gratitude, strengthens company culture, and reminds teams that today’s “normal” was once hard-won progress. They also share practical ideas for visualizing improvement over time, from “Lean scoreboards” to posting employee innovations without turning healthy pride into toxic competition. Later, Jay tells the story of an unexpected visit from a high-profile YouTuber and how Lean principles can impact any business from machining to media production. The episode wraps with a fun tangent into dive watches, trust (or mistrust) in AI tools, and Amazon’s not-so-Prime delivery promises.

Fresh off the Gemba Summit in Belfast, Andrew shares lessons from across the pond with Jay. What starts as a deep dive into lean culture at the Titanic Belfast turns into a candid conversation about scaling small businesses, visiting your vendors, and rethinking what it means to “fix what bugs you.” Andrew and Jay unpack how lean principles evolve when your company outgrows the two-second mindset. Andrews tells about conversations with Toyota UK’s Alan Weir, British Rototherm’s Oliver Conger, and Tom Hughes of GembaDocs. They also discuss the practical takeaways from Greg Crabtree’s Simple Numbers and Jerry Wright’s The Insanity Trap.

How do you lead your company through the chaos and cadence of a production year without burning out your team or yourself? In this episode, Jay and Andrew unpack Andrew’s “Four Quarter Business Rhythm” document, his framework for understanding seasonal production cycles, planning proactively, and preparing his team to thrive when it's go-time. From practical PTO policies to government fiscal-year quirks, from proactive inventory planning to Lean Day Trello boards, from baseball stats to busted CNC foot pedals, this episode is packed with leadership lessons, hard-earned shop wisdom, and actionable strategy.
