Perfect round cuts, sections made of metal, cuts made in straight lines – these are just some of the operations you can do with a pendular model, if you know how to use it correctly.
The vertical or pendular saw is one of the most useful electrical tools you can have in the workshop. Works well with a variety of materials and can be easily adapted to different types of cuts. However, it is much less used than would be expected. Here are some of the secrets that can help you use this device to its full potential.
Always choose the right blade
If for those who have years of experience working with such cutting devices, selecting the right blades for each project is an almost intuitive gesture, beginners can easily miss a cutout because they have not used the right accessory.
It is important first of all to choose the canvas depending on the type of material you will work with (metal, wood, chipboard, ceramics). A blade designed to cut wood will not handle the hardness of the metal very well, and if you try to use the wrong ceramic blade, you can easily break it.
Beyond this fairly simple criterion to follow, because the description of the blades usually includes the type of material for which they are made, the width of the blade and the type of teeth also matter.
The wider blades give you more stability, which is why they are better when you have to cut following straight lines or just slightly curved, which stretch over larger segments that require you to keep the direction for longer. Narrower variants mean less stability and greater mobility and will help you quickly and easily change the sectioning direction, following without difficulty lines that continue in tight curves or sharp angles.
The size of the teeth influences the fineness of the obtained edges and the speed of advance. A blade with large teeth will “bite” faster and lighter from the material, but will leave behind several traces of its passage, in the form of chips and streaks. On the other hand, choosing a cloth with smaller and thicker teeth will work slower, but the edges will be much cleaner and better defined.
The metal is more pretentious, looking for a suitable canvas
As you well know, you can also use a vertical saw to go through medium-hard metal sheets, copper pipes or wooden boards in which a few nails remained stuck (but pay attention to the difference in structure). In most cases, the metal blades are provided with small, although, hard and sharp teeth, which can cut the sheet. However, the efficiency of the blade also depends on the thickness of the material. As a guide, experts say that when you hold the canvas near the sheet, at least three consecutive teeth should be covered by the thickness of the material.
You can also cut in a straight line with a pendulum
In general, for straight and long cuts it is recommended to use the circular model, which has a better stability and is designed for such operations. But you can get a clean section of this type with a pendular model. For this you still need a guide element.
Attach to the work table a metal bar, a piece of wood or chipboard or MDF parallel to the line you need to cut. Then place the material so that you can support one side of the saw by the guide element, while the blade cuts on the drawn path. For everything to go well, it is important that both the wood or the metal you cut and the one you use to move straight are well fixed.
For perfect circles, use an adapter
When it comes to cutting circles, it is best to use a pendulum saw . It is best able to cut curved lines without hesitation and imperfections. However, the quality of the result depends on how safe your hand is on the device, so for perfect circles, we recommend that you do not rely only on your ability to concentrate.
Use a specially designed adapter to allow the blade to move around a point at a precisely measured radius. The adapter attaches to the material at one end and attaches to the saw at the other, allowing controlled rotation around the point of origin.
Cut with fine edges
The standard blades made for vertical saws have teeth oriented upwards, which means that the cutting and dislocation of the material takes place from the bottom up, and the upper part of it will mean edges surrounded by small splinters and unevenness. It is therefore important to place the wood or chipboard face down in order to benefit from the fine edges of the blade exit points.
In cases where the work material is fixed and you have no way to turn it, you can solve the problem using a blade with teeth facing down, ideal for situations where you need, for example, to create space in the top of a cabinet to install sink or built-in hob. These options are not expensive at all and you can buy them from any store that sells saw accessories.
It is as important as using a cloth with inverted teeth to protect the work surface, with paper or masking tape, so as not to scratch it when working, due to the friction of the metal base of the device on the material.
Very good visibility
Pendulum saw is a tool designed for detailed work. You can’t cut accurately, following complex patterns or strange angles, if you can’t see the marks you made for sectioning. So make sure that the work surface is always clean while cutting, and this means using a vacuum cleaner to remove the sawdust from your path as soon as it forms. Many saw models are sold with this accessory, but not all, so you may need to purchase it separately.
