This week, we're talking machines! One of the most critical steps in building our duck calls begins in the machine shop. Every call we make passes through one of our four HAAS     machine—starting as a solid rod of acrylic and ending as a precision-cut duck call blank. Spence is joined by Daniel, Jay, and Russ—our three machinists who help keep the Rolling Thunder world turning. The guys dive into the machines they run, how they use them to craft our calls, and share their backgrounds and experiences working with large CNC equipment.
