Theoretically, a pendulum saw is not difficult to use, but in practice, there are quite a few technical details that can make the difference between a precise and clean cut and a piece of broken material. Before you start working, find out some of the most important things to keep in mind in order to work easily and efficiently.
Do you like to do all kinds of repairs around the house, which involve cutting wood and metal? Surely you have thought at least once to buy a pendulum saw for operations that involve careful sectioning and details difficult to follow. If you have managed to complete your tool collection with such a device, we provide you with a short tutorial that marks the most important aspects that you must take into account when using it.
Pendular or circular
Most craftsmen have both versions and it is important to know clearly when each one is used. The vertical model has a smaller contact surface with the material it works on, a thinner blade and, consequently, more mobility. This property makes it perfect for cuts that involve curved or broken lines, tight angles, complex patterns, but over short distances. If you try to cut a longer line you will find that it is difficult, your hand runs a little to the side and it is difficult to maintain direction.
By comparison, the circular saw is designed for very good stability to long cuts, the design making it difficult to deviate to the left or right.
Type of material
The vertical saw works best with materials of medium hardness such as wood, chipboard, MDF, PDF, OSB or HDF, or plexiglass. It can also be used to cut metal, but the results are not great, more suitable for this type of material being the flex. On the other hand, you can also use it to cut ceramics, but you need a special canvas.
In order to be able to work easily and to make clean and precise cuts, it is important to use the right canvas for each material, taking into account its thickness, otherwise you will have difficulties in following the guides.
Familiarize yourself with the device
Read the technical manual, get acquainted with the operating system, how to fix the blade, the conditions of use and maintenance, etc. Find some scraps of material you don’t need and draw routes to test the accuracy of the device and your skill.
Make sure you know exactly how to control the device before starting a serious project. Try several types of blades so you can easily choose the right one.
Start cutting only when the blade is at full speed
If you enter the material with the canvas immediately after starting the device, without giving it the respite to reach the maximum speed, you will have to deal with vibrations large enough to turn a clear line into a kind of zigzag. zag nehotarat. Every time you start cutting, let the saw run for a few seconds and only then start working with it.
Sometimes it can happen that you stop cutting in the middle of the route. Before moving on, give the canvas about an inch back, turn on the appliance and let it reach its maximum speed and only then continue cutting.
Secures the material well for precise cutting
It is not enough to be in control of the movement of the saw and ensure a precise direction, you also need a very stable material on the work surface. So make sure you have at hand clamps or vise or other fastening systems that can hold the wood or metal fixed, despite the cutting movement and vibrations produced by the device. If the material moves, even a few millimeters, the cut will be crooked.
The importance of the cutting angle
If you want to cut straight, it is important that the canvas has a perfectly perpendicular position on the cut material, and this means that the sole or base of the saw is always in contact with the work surface, completely, so not bent towards the front or back.
If the base deviates from the horizontal, the canvas will enter the material obliquely and its length may not be enough to pierce the wood, chipboard, MDF, etc. diagonally. Also, because you work with a good face down, there is a risk that the cut will look completely different on that side than what you did on the side facing you.
You work better on a clean surface
The best pendulum saws are equipped with a blower or vacuum cleaner, and most models have a plug on the back that allows you to connect such accessories that you can buy separately. These devices allow the removal of sawdust generated after cutting, from the surface of the material, and help you better see the route you need to follow.
The material needs protection
When the sole of the saw moves on the material, under your pressure, it can damage it. If it is important for that face to look good, then cover the base of the device with some masking tape to prevent scratching. You can also apply the masking tape directly on the material, taking care to leave the cut marks visible or to make them over the tape.
Another aspect that is good to keep in mind is that with a standard pendulum saw, the face facing you will not look as good as the one facing down, because the blade cuts from the bottom up. will leave the edges on this side slightly fringed. The cuts will be less clean in the exit area of the blade, so choose carefully how to place it depending on which side should come out flawlessly.
Adapt the canvas to the complexity of the route
For cases where you work with cuts in straight lines, without tight angles and maybe, over slightly longer distances, a wider canvas will be helpful, which has greater stability. But if you have to cut curved profiles, with sudden turns, you will manage much easier with a narrow blade, and possibly with teeth on both sides.
