24 - Center-Finding Ruler (Dual-Scale)!

Finding true center shouldn’t require math, and that’s why I like a center-finding ruler. The dual-scale design measures outward from the center, so you align the edges and mark center lines instantly. It speeds up layout for hardware, mortises, dowel holes, and anything symmetrical.

Pros

+Finds true center quickly with no calculations
+Reduces layout errors on repetitive work
+Great for symmetrical marking tasks

Cons

-Specialized—doesn’t replace a standard rule for all measuring
-Works best on straight, consistent edges
