Within Tolerance is a machining podcast with dirt under its fingernails and CAD/CAM in its bloodstream. Dylan Jackson hosts conversations from the world of Protean Machining, where machine tools, customers, software, and shop logistics all collide in real time. The show is aimed squarely at machinists, and it talks like it. Episodes do not separate technical work from business stress. A discussion of five-axis limits can sit beside a story about moving a machine, chasing payment, rebuilding a website, or trying to make space in a shop that filled up faster than expected. That mix gives the show its shape. The technical side is specific: turning spindles, volumetric accuracy, Hermle maintenance, CAM automation, robots, pallets, tooling, quick disconnects, and complicated tolerance work. The business side is just as present. Guests talk about one-person shops, production pivots, ERP tools for job shops, customer communication, late invoices, and the constant tradeoff between growth and sanity. Zap’s recurring check-ins bring a serialized feel, with travel, partnerships, California work, Boise packing, Toolpath plans, and the day-to-day pressure of keeping momentum. Other guests widen the lens. Devin Bodony talks Lichen Precision and machine growth. Curt Van Filipowski brings garage-built titanium pens and EDC craftsmanship. Jamie Peacock explains JSpec Engineering and the one-man-shop rhythm behind The Lone Machinist. Juan March and Blake Nazario discuss InFab, software for job-shop workflows, and the value of talking to people who actually run machines. The result is technical without becoming sterile, casual without losing substance, and blunt about the parts of manufacturing that rarely make it into clean case studies. Within Tolerance works best for listeners who care about both the cut and the context around it.
