The Stone Carver’s Apprentice: How CNC Technology Is Shaping the Future of Monument Craft

In Season 2, Episode 2 of Monument Matters, Ross Oglesby of Keystone Memorials and Dan Weeres of Coldspring discuss how CNC technology is reshaping the monument industry. They share real-world experiences—from early machine failures to five-axis sculpture work—and explain how digital modeling improves accuracy, safety and customer expectations. While CNC machines excel at stock removal and precision moldings, both emphasize that skilled craftsmen remain essential for finishing and artistic detail. The conversation highlights how technology serves as an “apprentice,” removing heavy lifting while allowing sculptors to focus on proportion, refinement and artistry.
