In this video I’m showing you how to change the depth gauge settings on my TruBind TB S20A automatic coiling machine, because this is one of those little adjustments that can save you from big binding mistakes. If you’ve ever punched a whole stack and then realized your holes are sitting too close to the edge (or too far in), you already know how frustrating that is—especially when you’re binding homeschool curriculum, planners, or anything you want to hold up to real daily use. I walk through how I choose a depth gauge setting and what I’m looking for before I commit to punching a full book. I also share my real-life experience using basically one setting most of the time and how those books have held up for us. My goal is to help you get clean, consistent results so your coils turn smoothly, your pages don’t tear out, and the finished book actually feels sturdy. If you’re binding at home for homeschooling (or just trying to make your home office setup work better), this quick adjustment is one you’ll want to understand.
