Step 1
Think about straight cuts when learning to use a jig saw. The jig saw blades run on a true path. When the blade is in place in a jig saw, it runs up and down on the roller in a straight action. In the straight-cut position, the saw blade actually cuts slower and creates a smoother cut.

Step 2
Make a straight line cut with a jig saw by measuring an equal distance on each end of the board you need to cut. Now, measure the shoe of the jig saw to the center of your jig saw blade. This tells you where you need to put a stop down the board. This allows you to run your jig saw with its shoe up against the stop, thus making a straight cut down the board.

Step 3
Use your jig saw to make orbital cuts. Orbital cuts on a jig saw means that the blade makes a small rotating circle when it moves up and down. There's a dial on the side of the jig saw that gives you different settings for this orbital cut. The dial can be set for a range of circle sizes, from small to large. This makes the jig saw blade cut through most woods with ease and speed.

Step 4
Cut an orbital pattern using a jig saw. For example, the easiest way to cut a circle with a jig saw is to take a scrap piece of wood. Put a nail in your scrap wood in one end. This acts as a compass on the other end of the board, which will move. Measure the foot distance from one edge to the center of the blade. Drill a pilot hole in the board you're cutting a circle in. Slide your jig saw blade in the pilot hole, keeping the foot of your jig saw against the scrap wood. Cut your circle.
