What do we cut from?

If the goal of our work is to create an object with high aesthetic characteristics (and this is the case in most cases), then we need to start with the choice of material.

Plywood for cutting with a jigsaw must meet a number of requirements:

  • First, you should select the optimal sheet thickness. If we cut out a curly piece of furniture from plywood with our own hands, then we can use panels 12-15 mm thick, and even thicker ones. If our goal is more delicate work, then, accordingly, we need to purchase material of 5 mm or even less.

Different thicknesses for different applications

  • The color of the veneer from which the plywood is made plays a role only if we do not plan to carry out the finishing of the finished product with stain, varnish or paint. But most often they don’t pay attention to the color, it won’t be visible anyway!
  • The moisture content of the material is a critical parameter especially for jigsaw cutting. Plywood sheets must be thoroughly dried, otherwise our main occupation will be replacing the files.

As for the quality, only plywood of the first or second grade is suitable for artistic cutting:

  • There should be no knots or spots on the sheet.
  • There should be no resin pockets inside the slab.
  • Select only those panels for which the veneer is glued with sufficient quality.

Sawing with a jigsaw from plywood: technology, preparation, basic operations and safety

Sawing with a hand jigsaw from plywood is a technology that makes it possible to produce the most bizarre shapes. Over, it can be used both in the manufacture of designer furniture, making rather large elements, and in decor.

The basics of cutting are quite easy to master, and practically no equipment is required for them. Well, to do a really difficult thing, you have to work hard, however, this statement is true for almost any hobby.

So, we figured out the material. Now let’s focus on the inventory that will help us make furniture and plywood figurines.

Of course, the jigsaw itself will take a place at the head of our list.

The choice of a tool model depends primarily on the goals and objectives that you set for yourself:

  • Fine work, such as decorative sawing on plywood to decorate frames, boxes, etc., is done exclusively with a hand jigsaw. The frame of the tool can be either metal or wood; this does not have a special effect on the final result. (see also the article DIY plywood box for a detailed manufacturing guide)
  • When choosing a hand-held jigsaw for cutting out of plywood, pay attention to the quality of the saw attachment. Reliable screws will allow us not to waste time on correcting the position of the blade every five minutes of work.

Manual jigsaw with correctly positioned saw blade

  • A regular jigsaw is only used for fairly rough work, such as making furniture and large accessories. This is due to the fact that at a high speed of movement of the saw, chips are inevitably formed on the end part of the plywood, and therefore it is almost impossible to work with thin material.

Such a tool is only suitable for rough work.

  • When choosing a jigsaw for artistic cutting, remember that the price of the product is directly proportional to the quality of the cutting line. The thing is that in inexpensive models, literally after a couple of months of active use, the blade begins to walk in a horizontal plane, and the sawing accuracy drops. (see also the article Sawing out of plywood with a jigsaw: drawings and technology)
  • A separate category is electric jigsaws with bandsaw, which can also be used for artwork. These devices are small machines in which the workpiece is located on a special site.

Band saw machine

In addition to the jigsaw itself (and preferably two: electric and manual), we will need:

  • Plywood saws. The more stock, the better, since the file is literally a consumable.

Oversized jigsaw blade

  • A drill with a set of wood drills (below we will tell you how it can be useful for moms).
  • A set of files for smoothing edges. It is advisable to choose files of different shapes: at least straight, semicircular and triangular should be required.
  • Hand tools hammer, chisels, pliers, etc. Used to assemble sawn parts.
  • Awl and pencil for transferring drawings to plywood.

It is best to work on a special workbench equipped with a ledge for placing the workpiece for cutting. If there is no workbench, you can adapt a regular table for work by fixing a special sawing platform on it.

The platform is a wooden or plastic block with a specially shaped hole, which is attached to the table top with a clamp.

Safety engineering

Sawing out of plywood does not apply to traumatic activities, but nevertheless, safety rules must be observed:

  • For work, use only serviceable tools.
  • Do not cut using saw blade debris or band saw fragments.
  • Insulation should be checked when operating a power tool to avoid electric shock.

Eyes and hands must be protected

  • Sawing with a jigsaw or a band saw is carried out only on a special workbench, while the cutting part of the tool must be limited by special devices (frames, shields, etc.).
  • During the work, you need to use personal protective equipment: glasses, gloves, an anti-dust mask or respirator.

Material base

So, the preparation is complete, and you can proceed to the first attempts to cut something out of plywood with your own hands. Of course, if you’ve never picked up a jigsaw before, then practice on simple products before embarking on a large-scale project. Furniture work with a jigsaw

Work begins with sawing out the contour of the workpiece, after which the internal cuts are made. To make a through hole, first drill the plywood with a drill, and only then insert the jigsaw blade.

Below we describe the sequence of basic operations using a hand jigsaw. The use of an electric or band saw has its own nuances, but having mastered the basics, you will not experience difficulties when working with more advanced equipment. Straight cut

The simplest operation is to cut in a straight line.

The instructions for this operation are as follows:

  • Insert the jigsaw file into the drilled hole so that the teeth are directed towards the handle.
  • We stretch the canvas so that it does not vibrate during operation, and fix it with a screw.
  • We put the workpiece on the workbench, press it with the left hand against the sawing table and gradually start sawing.
  • When cutting a straight mowing line, move the jigsaw up and down, gradually feeding the workpiece under the saw.
  • Control of straightness of the cut can be ensured by placing a guide bar on the workbench.

Tool position when cutting

Curly sawing is more difficult, and you should start it only when you have fully mastered a straight cut:

  • We fix the jigsaw file in the same way as in the previous case.
  • We lay the workpiece with a clearly drawn line on the workbench.
  • We saw with movements from top to bottom, feeding the plywood with our left hand so that the blade does not go beyond the mowing line.
  • When the saw blade is displaced in relation to the mowing line of the template, stop moving with the left hand until the saw starts to move freely. After that, we correct the position of the plywood and continue working.

According to this principle, all elements are cut, including obtuse corners. But it is not worth cutting out an acute angle by turning the workpiece, since there is a high risk of breaking off the final fragment. In this case, two cuts should be made, connecting them at the top of the corner. We process the edge of the workpiece with a file

After cutting out all the elements, the workpiece must be filed, since even the most accurate work does not allow making a product with perfectly smooth edges. Using wood files, we carefully grind the outer and inner mowing lines of the cut, after which we process the entire workpiece with sandpaper and sandpaper.

The final stage is the finishing of the product. Plywood can be stained, painted or varnished.

Hand jigsaw sawing: a familiar tool from a new perspective

First of all, you should correctly organize the workspace. Despite the seeming formality, this is a very important condition. A properly equipped place provides not only comfort and convenience, which is important when working with a hand jigsaw for many hours, but also directly affects the quality of the project being implemented.

A special table-machine is used as a persistent structure, behind which the name dovetail is stuck. It is a small rectangular board with a wedge-shaped cut that turns into the working field for sawing. The dovetail is attached to the edge of a table or workbench with a clamp.

They work with a manual jigsaw while sitting or standing, placing the workpiece for cutting at a level of 30-40 cm from the eyes. The light source is placed at the front at an angle to the work plane. Compliance with these rules will allow you to control the cutting line as accurately as possible, thereby improving the quality of the project being cut.

What to do if chips are constantly appearing?

The number and sizes of chips depend on the type of plywood used, the quality of the blade and how correctly the master cuts. Sawing with a manual jigsaw without chips will help a few tips and professional tricks:

  • Using low-quality plywood that is prone to chips, saw more intensively, setting blades with a fine tooth;
  • Use a reverse (reverse) tooth file designed to minimize chipping.
  • Glue the mowing line of the cut on the back side with tape or masking tape;
  • Moisten the back of the workpiece.

What plywood is needed for jigsaw cutting?

Practice shows that the best material for working with a hand jigsaw is birch plywood with a thickness of 2 to 8 mm. It is affordable, easy to handle and highly durable.

To create small details or a dense openwork pattern, it is more appropriate to use three-layer plywood up to 3 mm thick. It is easy to cut and is quite durable. The likelihood that you ruin the cut curl with the next seizure of the canvas is significantly lower.

When choosing material for crafts, pay attention to the fact that the plywood is even and without a lot of knots. Examine the end face for the presence of air chambers, their presence indicates an uneven application of glue. It is better to refuse such low-grade plywood, otherwise you cannot avoid a large number of chips that will spoil the appearance of the product.

Let’s get to the point. How to cut with a jigsaw from plywood and wood?

To get an accurate and accurate cutting line, a number of basic rules should be followed:

  1. The hand with the jigsaw should only perform vertical movements.
  2. Movements up and down are performed without sudden jerks and with maximum amplitude in order to use the entire working length of the blade.
  3. The second hand in the process of sawing smoothly unfolds and moves the workpiece.
  4. There is no need to press on the workpiece with a file and exert lateral pressure on the blade.
  5. Sawing only occurs when the saw is moving from top to bottom, so the reverse movement should be carried out freely without pressure.

Working with a hand jigsaw, it is not led along the mowing line of the pattern, but along the inner side of the contour, since even the thinnest blade leaves a cut, the width of which should be taken into account. This is especially important when sawing products with precise fit, such as puzzles or intarsia.

When you are finished, remember to loosen one of the clamps so that the jigsaw frame does not lose its elasticity.

Which jigsaw to choose?

Despite the simplicity of their design, modern hand jigsaws differ in a number of features that should be paid attention to when choosing. It is better to refuse models with a sheet metal frame by choosing a jigsaw made of a metal tube. This option provides better blade tension and eliminates skewing, so that the file will not go away during operation.

The saw is fixed in the frame by tightening the upper and lower wing nuts. When choosing a jigsaw, pay attention that it is completed with lambs made of high-quality steel, which have wide ears. This will significantly increase the usability of the tool in the process.

Jigsaw sawing rules: diagrams and drawings

To start cutting with a jigsaw, diagrams and drawings are prepared in advance. When creating furniture, interior elements (shelves, doors) and finishing work, the skill of cutting with a jigsaw may be required. This process requires attentiveness, clarity of movement and accuracy.

Sawing with a jigsaw may be required for finishing work, but most often in the process of making furniture with your own hands, shelves and other things.

Preparatory work

Previously, the wizard transfers the drawing to a sheet of plywood. During cutting, it is necessary to hold the tool correctly, observing safety measures.

To cut out parts with a jigsaw, you will need:

Usually, with experience, the craftsmen immediately apply drawings to the surface, but for beginners, you will need special adhesive paper, tracing paper.

When assembling furniture and creating large parts, straight cuts are made without artistic wood cutting. In this case, experts recommend using an electric jigsaw. When cutting out small parts and curly elements, a hand tool is used.

Expert recommendations

When choosing a tool, attention must be paid to ensure that it is appropriate for the work being performed.

To cut a high-quality part with your own hands, use high-quality raw materials. The electric jigsaw must be held vertically, without tilting or loosening, making smooth up and down movements during operation.

The plywood moves towards the tool. The craftsman must ensure that the jigsaw does not vibrate. Otherwise, the wood will split. Improper use of the tool can cause it to get stuck in the wood or break the saw blade.

In the first case, the product will be damaged, and in the second, the master may be injured. Before cutting out the inner contours, it is necessary to make holes with an awl or drill. Then the tool is inserted into the holes and sawing begins. Experts recommend monitoring the position of the saw teeth and making turns without stopping the cut. The blade must be sharp, well taut, correctly positioned and firmly fixed to avoid injury.

A pattern carefully applied to the surface of plywood is half the battle when creating a quality piece.

A pattern carefully applied to the surface of plywood is half the battle when creating a quality piece. For this, pre-prepared sketches and tracing paper are used. The cost of tracing paper is not high, but the process of transferring the image onto plywood will require high concentration and precision of movements.

Transferring patterns to wood using tracing paper can be replaced by image projection. The required pattern is displayed on the plywood sheet using the projector. The working surface must be firmly fixed so that the pattern does not move. The disadvantages of the method are the need to purchase a projector, the cost of which is an order of magnitude higher than tracing paper. This technique is used for transferring small images. The third method of transferring the pattern to the work surface is self-adhesive paper. The sheet with the image is glued to the plywood. With this technique, you can get accurate mowing lines.

Carving simple shapes

Cutting simple shapes from plywood is quite simple, you just need to clearly adhere to the drawn lines.

To cut simple shapes from plywood, it is recommended to correctly transfer the drawing to the surface, observing the rules for working with a hand tool (taking into account the lines drawn on the wood).

Arcs and smooth mowing lines are cut without turning the tool, but directing the teeth strictly along the mowing line. You can make neat obtuse and sharp corners if you know a few nuances. Obtuse corners are cut using a turn-in-place technique (the foreman makes a straight cut and then unfolds the plywood sheet).

Loop formation is suitable for creating sharp corners. To do this, it is necessary to cut one side of the corner, and then a loop is cut along the outer contour, which allows you to immediately create the 2nd side of the acute outer corner. The sequence of actions helps to make neat internal cuts:

  • Make holes for sawing;
  • Cut the sheet along the pattern to the top of the corner;
  • Return the plywood to its original position;
  • Cut out the 2nd side of the corner.

To create decorative elements with a jigsaw, the master will need plywood, tools, good lighting, and an eye. The work is done slowly and accurately. Haste can lead to uneven corners and oblique cuts.

Beginners will be helped by step-by-step instructions, professional advice (to create artistic elements, you need to know special techniques for working with a jigsaw) and regular practice. Sawing with a jigsaw takes patience and dedication. Do-it-yourself decorative wooden products can be used to decorate the interior of your home and office.
