I wanted to make this quick video for YouTube to show how I navigate thimble chimneys using a simple, reliable setup. I use a lightweight corrugated tube—about four inches in diameter—like the ones used for dust collection. I cut a small piece to help guide my modified camera, which I’ve trimmed down for easier movement in tight spaces. I slide the camera into the tube, use a half-inch rod for flexibility, and it moves smoothly around turns. Pulling it back is just as easy, with the cable staying tangle-free. This method, paired with prefabricated parts like a standard damper, keeps my camera safe and inspections effortless.
