Carpentry is a profession I love and very good at not only because of my training but also because of it is a family skill. What amazes me is how much technology has changed over the years.
Today, I can design and construct whatever I conceive because of the convenience of machines like a jigsaw. What is jig saw? How can you use a jigsaw?

What Is Jig Saw?
A jigsaw is a powerful tool designed to use a reciprocating blade (a blade that moves up and down rapidly) and a motor to make irregular cuts and create the format for detailed, decorative work.
Many people prefer jigsaws for their versatility. Personally, I love them because they replace other table power saws such as band saw and scroll saw.
In fact, a jigsaw is capable of handling almost all curved cuts perfectly. Even better is that it is affordable and takes very little space. Some people may call it sabre saw or bayonet’ saw. A jigsaw can make stenciled designs not only on wood but also on metal, plastic and other material.
How to Use Jigsaw?
Jigsaws create very nice precision cuts but only if you can use it correctly.
First, you have to ensure you buy high quality saw with a high-quality blade. Here is how to use a jigsaw for cutting intricate shapes and for making bevel and compound cuts on wooden boards and other materials.
Step 1: Select the Correct Blade To Use
You can use a jigsaw to cut almost any material from plywood to stainless steel sheet as long as you can use the right blade for the material you are cutting. Among the things to consider in choosing the reciprocating blade are blade composition, blade teeth per inch (TPI) and blade width.
Step 2: Prepare the Work Piece For Your Cut
After picking the right blade, you should now think of making the workpiece you are cutting for the actual cut.
Remember the material you are preparing must be the right one for the blade you are using. It would be disastrous to use a blade made for wood to cut into a stainless steel sheet.
Step 3: Identify the Cut Lines
You need cut lines on the work piece above to make accurate cuts. Identify the cut lines by measuring and marking it with a pencil or other marker. If you intend to make shapes like sink cutouts in countertop, the best option is to use the actual sink as your cut line.
For special projects or other shapes, you will do well by creating a template for your cut out of cardboard on paper. This will make the cutting process easier and more precise.
Step 4: Stabilize the Material You Are Cutting
Using your jigsaw will be much easier if you place the material you are cutting on a workbench or saw horses, or clamp it in a vice depending on what works best for you. This will leave both of your hands-frees to guide the saw to allow for more accurate and creative work.
Step 5: Place the Saw Close to the Edge of the Material to Cut
In order to begin the cutting, you need to position your jigsaw close to the edge of the material you are supposed to work on.
Begin cutting by slowly and progressively squeezing the trigger of the saw. When the saw is running at the desired speed, push it forwards into the material you are cutting.
Step 6: Guide the Saw Correctly, As You Cut
For smooth and accurate cut, make sure you guide your saw along its path by twisting its back in the opposing direction you wish your blade to travel. Try your best to keep the blade aligned with the cut line.
Be keen when sewing with a jigsaw. If the saw starts to load up or tends to sound like it is straining, slow down the forwards speed. Cutting too fast may overheat the blade, and the saw motor resulting in splintering in the material you are trying to cut.
Step 7: Clear Sawdust or Debris
During the cutting process, sawdust or debris tend to accumulate on the workpiece thereby blocking your view of the cut line. The waste material may also interfere with the travel of your jigsaw.
If this happens, stop the saw and blow the debris. Restart the saw once you remove the line. Do this by backing it slightly. In all you do, please do not turn on the saw while its blade is engaged in the material you are cutting. Doing so might destroy the loose blade.
Step 8: Complete the Process
You can complete the cutting process once you have cut through the entire cut line as you measured and amerced them.
Ensure you support any piece that may drop when you finish the cut until the saw blade is free from the piece. You can repeat the process for all your cuts.
1. What are the essential parts of a jigsaw?
The basic jigsaw parts to know include blade, shoe, blade clamp, handle, power cord (for corded- electric), on/off switch, speed control dial, orbital action dial, and lock on button.
2. What are the different types of jigsaw handle?
You can choose from three different types of jigsaws. These include corded-electric, cordless/battery powered and pneumatic jigsaws.
3. What is the power of a jigsaw?
Most jigsaws have reciprocating blades that powered by an electric motor. The corded versions are powered by mains electricity while the cordless versions use rechargeable batteries. Pneumatic version uses compressed air.
4. How does a jigsaw work?
Jigsaws usually cuts on the upstroke because of its teeth that point upwards. The blade is reciprocating means the motor moves it up and down to cut.
5. Can I cut sheet metal with a jigsaw?
Yes, jigsaws can cut into a variety of materials including metal sheets as long as you use the right blade meant specifically for that purpose.
I believe you cannot go wrong if you follow the above steps in case you have been looking for information on how to use a jigsaw. This power tool is one of the easiest to use. If you employ the right techniques, this versatile tool can be useful for cutting all manner of curved cuts.
