Large-scale Center Finder

By Woodcraft Magazine Updated on: May 7, 2025 Published on: May 7, 2025

Plastic center finders are great for spindle turnings and smaller bowl blanks, but won’t work for larger blanks such as those for platters. For those, I make a bigger version by clamping a combination square to a framing square with the combo-square’s blade aligned with the vertex of the framing square as shown. Draw two intersecting lines along the combo-square’s blade to mark the center.

A Practical Alternative to Commercial Jigs

Many woodworkers rely on a store-bought center finder for woodworking, but when turning oversized blanks, those tools can fall short. Richard's large-scale solution doubles as a DIY center finder jig that costs nothing to make and works with tools most shops already have. The intersecting-line method gives a fast and accurate result and doesn’t depend on plastic guides or fixed radii. This simple alignment trick solves a common workshop challenge with ingenuity and precision.

Why Centering Matters

An accurate center is essential when mounting any blank on a lathe, especially for balanced turning and safety. A homemade center finding jig like this one ensures your platter blank spins evenly, reducing vibration and the risk of tool catches. In lathe work, a small error in marking can throw off your project from the start. This wood lathe center finder trick helps you lock in your layout before the first cut.
