Center Rules are great for layout when working from center lines and for laying out detailed joinery. Made from .029” stainless steel, these Center Rules are flexible enough to work on round logs and uneven surfaces. Decimal inch rulings on the top and bottom start from opposite zero points so you can work from either side without flipping them over and reading upside down.
Includes a fraction to decimal conversion chart and trigonometric ratio equations etched on the front side. The backside is a center rule with edge rulings to allow both center work and zero point work on the same rule.
