Today on the ProtoPod, we’re joined by Jim York from @ElliottMachinery for a deep dive into the world of metrology, GD&T (geometric dimensioning & tolerancing), and why so many engineering drawings break down in the real world.

Jim is a product manager specializing in CMMs (coordinate measuring machines) and has spent years helping manufacturers across Canada improve how they inspect, validate, and build precision parts.

In this episode, we get into:
⚙️ Why GD&T is often misunderstood in engineering education
📏 How metrology impacts real-world manufacturing performance
🛠️ Common mistakes engineers make in drawings and tolerancing
🚀 Why tighter tolerances matter in aerospace and advanced manufacturing
🧠 How CAD, AI, and model-based definition are changing inspection workflows
🎣 Plus: rapid fire questions, fishing stories, and why Lego teaches better assembly principles than you’d think

Whether you’re an engineer, machinist, student, designer, or manufacturing nerd — this episode is packed with practical insight.
