Roll along easily with template enlargements
Enlarging templates by small increments—such as 1⁄4 " or 1⁄2 "—can be a pain, especially when you're trying to increase the dimensions of a curved or irregularly shaped object. Sometimes, you need to draw template offset lines that match a router guide bushing. Here's a solution utilizing parts on hand.
Use a flat metal washer as a spacer between the edge of the template and the point of your pencil as shown above. Washers come in many different sizes, giving you a wide choice in enlarging capabilities. Maintain steady pressure as you draw.
