In this episode of Bench Tested, Charlie Harsh talks with Sean Charlesworth about what really makes a Ghostbusters build work. From his early love of the films to building detailed, functional props like ghost traps, the RTV, the Keymaster helmet, and the ESP shock machine, Sean breaks down the difference between props that only look right and props that actually feel right.

The conversation gets into 3D printing, engineering around real-world limitations, balancing durability with accuracy, why “screen accurate” is often more complicated than fans think, and how iteration is what truly levels up a build. If you’ve ever struggled with overthinking, design compromises, internal layout, or just getting started, this episode is packed with practical insight from someone who lives in that space between fan obsession and real-world problem solving.
