This clear acrylic center finder is a woodturner's and crafter's best friend! Need to find the exact center of a log, board, or any round object? Or draw perfect circles up to 300mm (11.8 inches) in diameter? This tool makes it a breeze. It's 5mm thick, so it's sturdy and won't flex, and the laser-etched measurement markings (in 1mm increments) are super precise and won't wear off. You simply place it on your workpiece, adjust until the circles line up with the edges, and mark the center point. It helps you find the largest possible circle from a piece of wood, minimizing waste – perfect for bowl or plate blanks. It's not just for wood; use it on plastic, metal, glass, poster board, and more for all sorts of arts, crafts, and school projects. Seeing through the clear acrylic lets you position it perfectly. Simple, durable, and incredibly useful for anyone who works with circles.
