In this episode of the Maker's Quest Podcast, hosts Brian Benham from Benham Design Concepts and Greg Porter from Skyscraper Guitars delved into the often-overlooked reality of failure in the creative process—especially when turning ideas into marketable products. Both seasoned makers shared candid stories of their struggles, lessons learned, and how embracing failure is a non-negotiable step toward innovation and profitability.

The CNC Learning Curve: Speed Isn’t Always King
Brian Benham, a furniture maker and CNC enthusiast, kicked off the discussion with his early trials on his new Avid CNC machine. His goal? To efficiently produce a yin-yang wine bottle holder. But his initial excitement was tempered by a harsh lesson:
"I watched YouTube videos where people said, ‘Why are you running so slow? Crank it up!’ So I did," Brian recalled. The result? Broken tabs, a mangled workpiece, and a smoking spindle. The high feed rate and aggressive depth of cut destroyed the part mid-operation.
Greg Porter, a guitar maker and CNC veteran, nodded in agreement. "Dust is bad—you want chips," he explained, emphasizing that proper chip ejection prevents heat buildup and tool wear. Both makers stressed the importance of balancing speed with precision, especially when working with different materials like cherry (softer) versus walnut (denser).
Workholding Woes and the "Maker’s Dozen"Brian also shared a mishap where inadequate hold-downs led to a shifting workpiece, ruining a cut. His solution? Nesting parts efficiently and pre-drilling problematic areas to avoid tab failures. But the bigger takeaway was his "Maker’s Dozen" philosophy:
"Make 12 units at a time. Price for 10, because two might fail. By the next dozen, you’ve optimized the process," Brian said. This approach minimizes waste and allows incremental improvements without massive sunk costs.
Greg added that for high-value materials (like exotic guitar woods), salvaging is worth the effort. But for sheet goods, sometimes tossing a botched piece saves more time than fixing it.
3D Printing: Prototyping’s Best FriendThe duo pivoted to 3D printing, where Greg showcased a gear assembly that took a dozen iterations just to fit a timing belt correctly. "Fail fast," he advised. "Get the mistakes out early."
Brian echoed this, describing how he prints small test sections (like threaded parts) before committing to long prints. *"A 30-minute test beats a 3-hour disaster,"* he said. Both praised modern printers for reliability but acknowledged that vibration and material quirks still demand patience.
Scaling Up: Robots and RevenueLooking ahead, Brian envisions his CNC as a cash-flow generator. Inspired by a photographer who sold everything from keychains to $5,000 prints, he plans to offer small, accessible products (like $25 cribbage boards) alongside high-end furniture. "The $25 items keep the lights on; the big commissions are the dream," he said.
Greg, who runs multiple machines simultaneously, laughed: "When all three robots—CNC, laser, mill—are humming, I feel like a factory." But he cautioned that optimization is key. His "RTM" (Ready to Manufacture) files undergo dozens of tweaks to shave seconds off cycle times.
The Bottom Line: Failure = ProgressBoth makers agreed: Failure isn’t just inevitable—it’s necessary. Whether it’s dialing in feeds/speeds, salvaging scraps into new products (like Brian’s failed cutting boards becoming trivets), or accepting that some ATMs (products) will stay unplugged, the path to success is paved with missteps.

The Burden
The Burden is a documentary series that takes listeners into the hidden places where justice is done (and undone). It dives deep into the lives of heroes and villains. And it focuses a spotlight on those who triumph even when the odds are against them. Season 5 - The Burden: Death & Deceit in Alliance On April Fools Day 1999, 26-year-old Yvonne Layne was found murdered in her Alliance, Ohio home. David Thorne, her ex-boyfriend and father of one of her children, was instantly a suspect. Another young man admitted to the murder, and David breathed a sigh of relief, until the confessed murderer fingered David; “He paid me to do it.” David was sentenced to life without parole. Two decades later, Pulitzer winner and podcast host, Maggie Freleng (Bone Valley Season 3: Graves County, Wrongful Conviction, Suave) launched a “live” investigation into David's conviction alongside Jason Baldwin (himself wrongfully convicted as a member of the West Memphis Three). Maggie had come to believe that the entire investigation of David was botched by the tiny local police department, or worse, covered up the real killer. Was Maggie correct? Was David’s claim of innocence credible? In Death and Deceit in Alliance, Maggie recounts the case that launched her career, and ultimately, “broke” her.” The results will shock the listener and reduce Maggie to tears and self-doubt. This is not your typical wrongful conviction story. In fact, it turns the genre on its head. It asks the question: What if our champions are foolish? Season 4 - The Burden: Get the Money and Run “Trying to murder my father, this was the thing that put me on the path.” That’s Joe Loya and that path was bank robbery. Bank, bank, bank, bank, bank. In season 4 of The Burden: Get the Money and Run, we hear from Joe who was once the most prolific bank robber in Southern California, and beyond. He used disguises, body doubles, proxies. He leaped over counters, grabbed the money and ran. Even as the FBI was closing in. It was a showdown between a daring bank robber, and a patient FBI agent. Joe was no ordinary bank robber. He was bright, articulate, charismatic, and driven by a dark rage that he summoned up at will. In seven episodes, Joe tells all: the what, the how… and the why. Including why he tried to murder his father. Season 3 - The Burden: Avenger Miriam Lewin is one of Argentina’s leading journalists today. At 19 years old, she was kidnapped off the streets of Buenos Aires for her political activism and thrown into a concentration camp. Thousands of her fellow inmates were executed, tossed alive from a cargo plane into the ocean. Miriam, along with a handful of others, will survive the camp. Then as a journalist, she will wage a decades long campaign to bring her tormentors to justice. Avenger is about one woman’s triumphant battle against unbelievable odds to survive torture, claim justice for the crimes done against her and others like her, and change the future of her country. Season 2 - The Burden: Empire on Blood Empire on Blood is set in the Bronx, NY, in the early 90s, when two young drug dealers ruled an intersection known as “The Corner on Blood.” The boss, Calvin Buari, lived large. He and a protege swore they would build an empire on blood. Then the relationship frayed and the protege accused Calvin of a double homicide which he claimed he didn’t do. But did he? Award-winning journalist Steve Fishman spent seven years to answer that question. This is the story of one man’s last chance to overturn his life sentence. He may prevail, but someone’s gotta pay. The Burden: Empire on Blood is the director’s cut of the true crime classic which reached #1 on the charts when it was first released half a dozen years ago. Season 1 - The Burden In the 1990s, Detective Louis N. Scarcella was legendary. In a city overrun by violent crime, he cracked the toughest cases and put away the worst criminals. “The Hulk” was his nickname. Then the story changed. Scarcella ran into a group of convicted murderers who all say they are innocent. They turned themselves into jailhouse-lawyers and in prison founded a lway firm. When they realized Scarcella helped put many of them away, they set their sights on taking him down. And with the help of a NY Times reporter they have a chance. For years, Scarcella insisted he did nothing wrong. But that’s all he’d say. Until we tracked Scarcella to a sauna in a Russian bathhouse, where he started to talk..and talk and talk. “The guilty have gone free,” he whispered. And then agreed to take us into the belly of the beast. Welcome to The Burden.
