How to Cut a 3-Foot Diameter Wood Circle
Cutting a 3-foot diameter circle in wood may be necessary to, for example, make a prop or a wheel to attach to a cart. One tool you may already have for this task is a jigsaw, which will allow you to easily cut the curves. To do this, you need to draw a pattern on a piece of wood such as plywood. Using a simple technique will enable you to draw a circle of almost any size.
