How to Use Pegboard to Enlarge Project Plans
Try this little trick next time you need to enlarge project plans; you probably already have everything you need right in your home workshop.
Scale plans are often drawn on a grid so you can readily enlarge the original drawing. But enlarging means redrawing the grid to a larger scale—a tedious and time-consuming job. I’ve found a quick way to recreate 1 in. grid with 1/8 in. thick pegboard. Just place the pegboard on your workpiece and center a dot in each hole with a pencil. — Dean St. Clair
