How to Use a Jig Saw

Use a jig saw when you need to cut out intricate and complex patterns. Most saws are best at cutting straight lines, but a jig saw will cut any pattern that you can draw. You can cut most materials with a jig saw--including wood, metal, plaster and dry wall--as long as you have the right blade. Most jig saws come with blades when you purchase them, but you can buy other blades to make your saw more versatile.

Things You'll Need

• Jig saw blades
• 2 saw horses
• Pencil
• Protective eye gear
• Gloves
• Wood file or other finishing tool (depending on your material)

Instructions

1. 

   Most jig saws can be used with many types of blades.

   Purchase a jig saw blade that is appropriate to the material you are cutting. Different blades are available for everything from wood to metal. Don't be afraid to spend a little money; as with everything, you are likely to get better quality if you pay more.

2. Install the blade into your jig saw according to the instructions. Often, installation is done by a twisting or locking mechanism directly above the blade housing.

3. 

   Using saw horses allows you to cut your material without impediments below.

   Place the material to be cut across two saw horses. Be sure that the area you are cutting is not sitting directly on top of a saw horse, to prevent your blade from hitting it. You may have to rotate your material on the saw horses while you are cutting if your pattern is large.

4. Outline your cutting template on the material with a pencil.

5. 

   Jig saws can cut curvy and straight lines.

   Begin cutting. Be sure the surface plate is flat to your material and begin on the outer edge. Move the blade slowly along your outline. If you are cutting into a fixed flat surface such as a wall, you will first need to drill a pilot hole large enough to accommodate the jig saw blade. Never start the jig saw unless the surface plate is flat on your cutting surface.

6. 

   Filing the edge of your cut material can prevent it from splintering.

   Use a rasp or other finishing tool (depending on your material) to smooth the edges of your cut.

Tips & Warnings

• It is best to buy the same brand of blade as your jig saw.

• Wear protective gear such as eyewear and gloves to protect yourself from flying material during cutting.

• As with any power tool, you are at risk of hurting yourself during use, so be sure to follow the safety instructions that come with your jig saw.
