How To Use A Jigsaw For Beginners, Easy Guide of 2021

For craft projects and other woodworking tasks, a jigsaw is a versatile power tool that allows DIYers and professionals alike to make straight and intricate cuts. If you learn how to use a jigsaw and choose the right type of blade, it will be easy for you to cut wood, metal, laminate, and tile like an expert.

How to use a jigsaw safely and effectively is described in this guide. 

Before Using A Jigsaw Required Safety Tools

    • Make sure you’re familiar with the user’s manual. If you are unable to locate the manual, contact the maker and request a copy.
    • Put on the necessary personal protective equipment (PPE). Impact-resistant eyeglasses, steel-toed boots, and a dust mask are examples. Keep in mind that it is the responsibility of the company to provide PPE to its employees.
    • Do not try to push the jigsaw through rugged or resistant materials. If the blade won’t cut, turn it around and try again.
    • Keep your jigsaw’s blade and surrounding components greased.
    • Other employees are advised not to approach the jigsaw while it is in operation.
  • Make sure you don’t trip over any extension cables attached to your jigsaw.

Uses of jigsaw Components

Even if you’re new to woodworking, the jigsaw is an immensely versatile tool that’s also simple to operate. However, a jigsaw is still a powerful instrument, and getting the most out of it requires learning about its components.

A jigsaw’s many components and functions allow you to cut materials other than wood, such as metal, plastic, and even ceramic. You can also make bevel and plunge cuts, in addition to straight and scrolling cuts, depending on the type of jigsaw and blade you have.

Finally, you may choose between a cordless or corded jigsaw, which means you can use a cord or a more portable power pack to run it.

  1. The metal foundation of a jigsaw is called the shoe. It’s also known as a baseplate or a sole. The shoe sits on the material to cut, ensuring that the blade remains at a constant angle to the workpiece. 
  2. Most jigsaw shoes may adjust at an angle to enable the instrument to create a bevel cut.

The angle of the shoe can change by removing the screw holding it in place or releasing the shoe adjustment lever if your tool features tool-less shoe adjustment.

  1. To stand with the vibrations created by the blade during operation, the shoe must be extremely robust. Pressed or cast aluminium, magnesium, or steel are the most common materials used.
  2. The jigsaw blade protrudes from the shoe and is square to it, performing the tool’s cutting operation. Most blades have teeth that are oriented upwards to cut on the upstroke. To achieve different finishes, blades with varied numbers of teeth are available. The blade determines the materials that a jigsaw can cut it has fitted.
  3. The blade clamp of a jigsaw keeps the blade in place. Some jigsaw blade clamps are made out of one or two screws released and tightened with an Allen key to hold and lock the blade in place. Blade changing on a jigsaw without the need for a key. On the other hand, keyless blade clamping methods are becoming increasingly prevalent, making jigsaw blade changes considerably faster and easier.
  4. Instead of screws, the blade is kept in place by a spring-loaded lever that may be engaged or disengaged to hold or release it.
  5. The blade roller guide supports the blade during cutting and is located above the shoe of a jigsaw. It is slotted between the guides to keep the blade at the workpiece and prevent it from bending
  6. The user can grasp a jigsaw’s handle, which may then guide the tool through the cut. One of the most noticeable aspects of a jigsaw is the sort of handle it has. There are two kinds of them: top handle and barrel grip.
  7. A jigsaw’s on-off trigger is generally placed beneath the handle and is used to operate the instrument when you press down on the trigger, the tool’s cutting speed increases until it reaches the maximum setting on the variable speed dial.
  8. Instead of continually holding the on-off trigger, a lock-on button allows you to lock the jigsaw at a specified speed. This feature makes the tool considerably more pleasant to use when cutting for lengthy periods, lowering user fatigue.
  9. When a jigsaw’s orbital action is turn on, the blade moves forward and backwards and up and down, resulting in a more forceful cut. The orbital action dial is used to determine the amount of forwarding movement the blade makes during each stroke. It may generally be adjusted to four or five different positions.
  10. The jigsaw’s top cutting speed may be adjusted using the variable speed dial. The dial is regulated, giving the user more control over their tool because the jigsaw’s speed should change to match the task and material at hand.
  11. The cable of a mains-powered jigsaw supplies electricity to the instrument and can be anywhere from 2m (612) to 5m (16′) long. The length of the cable is crucial when choosing a jigsaw since it influences the tool’s mobility and manoeuvrability. When not in use, certain jigsaw cables can be removed from the instrument. Jigsaws with detachable power cords are more convenient to travel and store.

Jigsaw Working

  • A jigsaw is a motorized saw that uses a motor to move a thin blade down and up in a fast motion.
  • The blade’s reciprocating action is remarkably similar to that of a sewing machine needle.
  • A pair of eccentric gears connect the motor to the blade within the jigsaw’s housing (gears that have axes that are off-center).
  • These gears translate the motor’s rotational action into the blade holder’s reciprocating vertical movement, allowing the blade to move swiftly up and down.
  • Because the teeth of a jigsaw blade point upwards, it generally cuts on the upstroke. If a clean cut is critical, flip your work piece over and cut from the rear of the material to avoid splintering on the front.
  • During usage, the tool’s shoe (base) is pressed on the work-piece. As the blade cuts up and through the cloth, the work is pulled against the shoe.
  • A variable speed dial may be used to change the speed of most machines.
  • In combination with the orbital action function, this feature allows the user to fine-tune the cut and work with a variety of materials. Wood is cut at high rates, whereas plastic and metal are cut at lesser speeds.

Jigsaw Care And Maintenance

It’s critical to properly care for and maintain your jigsaw so that it performs as effectively and precisely as possible. 

Before using the jigsaw

Jigsaw power cord, make sure you have a power lead. Check the quality of the power cable if your jigsaw is powered by mains electricity before using it. The machine is hazardous to use if the cable is damaged or frayed.

If you fall your jigsaw, the alignment of its shoe may be thrown off. In addition, a saw that has a twisted or broken baseplate will not be able to make precise cuts.

If you drop your tool by mistake, you may be able to repair minor damage by flattening the shoe with mole grips. However, if the shoe is significantly deformed, you may need to replace it or the entire jigsaw.

Greasing

Apply a bit of grease to the blade roller guide of your tool now and then to keep it from clogging throughout use.

Cleaning Process

Keep the ventilation holes clear of dust and debris to prevent your jigsaw from overheating while in use. Before and after use, make sure the handle is clean, dry, and free of oil or grease. Remove any filth from the body of your instrument with a wet cloth and mild soap. 

Above all, the blade guide should be kept clean and free of dust accumulation. Remove any unnecessary dirt with an old toothbrush that might damage the saw’s precision.

Storage Capacity

Some jigsaws, generally the higher-end ones, come with a secure storage box to keep them in when not in use. If your tool does not come with a protective case, ensure it is stored safely and away from moisture. 

Replacement of Brushes

Two carbon brushes deliver power to the motor in the majority of jigsaws. However, these brushes will wear out over time due to friction and will need to be replaced. The operating handbook will specify whether or not the carbon brushes in your jigsaw’s motor may replaced by hand.

Because the tools are often only used for a short time, a set of brushes will usually survive the tool’s lifetime and will not need to be changed.

Recharging Process

Like with other cordless equipment, keep a check on the charge in your battery to see whether your jigsaw has enough power to finish the work at hand.

The frequency with which you must charge your tool’s battery are determined by its capacity and the applications for which you have used your jigsaw.

How To Use A Jigsaw For A Straight Line Long Cut?

When using a jigsaw to make a straight cut, all you need is a good exact line and a jigsaw with a sharp blade to cut through it. Even while a jigsaw is ideal for curved cuts, it also cuts straight lines with precision, thus it may be used to do both curved and straight cuts.

A jigsaw can cut a wide variety of materials while cutting a straight line. The methods for cutting straight lines with a jigsaw vary depending on the straight line that has to be cut.

Blades

Different types of blades are clearly available for a jigsaw, based on the various materials and cut angles, and so on. When it comes to selecting a blade for cutting a straight line, there are two factors to keep in mind.

Between the rip cut and crosscut blades, there are times when you need to pick the right blade for the job. With the right mix of blades, it’s possible to get away Scot-free, but they’re picky about the materials they use.

Drawing A Straight Line

Because a jigsaw may make rip cuts and crosscuts, one might opt to use a measuring tape instead of a ruler. In contrast to using a ruler to measure the length and breadth of a larger piece of wood, this method allows you to quickly measure the width and length at the same time.

Drawing a straight line with grain may be challenging as well. If there is a lot of resistance on a wood surface, try using a tape measure and a fence to support it.

Along with the tape measure, a square can be handy in line sketching. The square can also be used as a guide while pressing the jigsaw down the line.

Makeshift Fence

It’s critical to place a guide on top of the material to be cut. It may also be used as a Makeshift fence since it fulfils the same function as a table saw fence. There are various methods for installing this, but only one one works correctly.

The fence is attached to the piece of wood using clamps. This allows a person to apply enough pressure to keep the guide in place without damaging the piece of wood. It’s possible that some timber from below the fence may need to be chopped.

In this scenario, the use of various attachment devices such as nails may not only harm the wood, but may also cause the fence to slope, causing an individual to get disorganized up a perpendicular straight line.

Keep in mind that the wood you choose to use as a guide must be exactly straight on the other side of the saw. A level and a sander are both useful tools for guaranteeing order and correcting any mistakes.

Wood Cutting

Then again, those have been completed and the necessary equipment has been installed. The only thing left to perfect in using a jigsaw to cut a straight line is manipulating the saw in the proper proportions of pressure exerted while moving the saw forward and downward.

The thickness of a material is a significant factor in influencing the force delivered to the wood by the jigsaw. To avoid harming the wood, use less power while cutting tiny pieces of wood. Applying too much power to thin softwood pieces might cause them to flex and splinter, resulting in a messed-up cut. Even with the guide attached to the wood, pushing the saw too hard may cause the saw to slide away from the fence, thus the operation requires delicate force.

How To Use A Jigsaw For Shortest And Cross Cut?

Simply put down a cutting line, start the jigsaw, and follow it to the finish to make a quick straight cut. A cross cut is a cut that runs counter to the grain of the wood.

Because most wooden boards and timber are constructed with the grain running lengthwise, the majority of cross and miter cuts you’ll make will be short straight cuts.

  1. To begin, use a measuring tape and a pencil to outline the cut’s dimensions. Then, using a square, draw out the cutting line on the workpiece, remembering to note the waste side of the cut.
  2. Then, to get a straight line, sketch a line with a speed square (if using smaller timber) or a framing square.
  3. Before making a cut, it’s a good idea to inspect the jigsaw blade for straightness and alignment. Make a quick check with a square to ensure that the blade is exactly perpendicular to the shoe.
  4. If a blade is bent or out of alignment, it can damage a cut if it snaps in the middle of a cut. – It’s best to be safe and get a new blade.
  5. With the shoe lying on the material, place the jigsaw near the cut. Turn the tool on and let it warm up before bringing it slowly into the work piece to begin the cut.
  6. You could also find that placing the blade on the material before commencing your cut helps it grip and prevents bouncing.
  7. All through the cut, make sure the work piece is kept firmly or clamped down, and concentrate on following the cutting line until you reach the finish.

Conclusion 

A jigsaw, to show it as a tiny saw designed to cut curves in light wood, is a far more flexible instrument. It’s small, light, and powerful enough to cut through most materials, especially if you use blades designed for that purpose.
