Have you bought a pendulum saw and want to use it as soon as possible, as well as a professional? Invest a few minutes to learn some of the tricks inspired by experience that can help you avoid a series of mistakes usually made by beginners.
If you managed to buy the dream saw for your workshop, it means that you are ready to enthusiastically section the first materials. For the best results, however, we recommend you to have a little patience and try to find out as many rules and tricks as possible about using this device, which will guarantee safe and efficient use from the beginning. Here are some of them.
The sole of the saw can damage the work surface
One of the basic rules in using this type of saw says that, in order to obtain a safe and without hesitation cut, you must firmly press the sole of the device on the work surface. Even so, there will be vibrations. The combination of small movements caused by the operation of the engine and the penetration of the blade into the wood and the pressure of your hand often leads to damage to the work surface by small scratches.
A trick you can use to prevent this is to cover the sole of the device with a layer of masking tape or apply directly to the fabric. This intermediate layer also helps you move the device more easily and will take over the mechanical aggressions.
Do not forget to remove the tape after you have finished cutting, so that the adhesive does not print on the saw or on the material and you have to spend more time removing it.
The cutting cloth must be perfectly perpendicular to the sole
Vertical saw models are built to perform precision cutting on straight lines, curves, angles, etc. However, this precision is only available if the blade is not worn or slightly curved. So, before you start sectioning after a marking that requires attention and very safe movements, carefully analyze the blade. If you see that it is not perfectly perpendicular to the base of the device, change it with a new one, and you can still use the old one for slightly coarser projects.
Protects the good side of the material
Most pendular versions penetrate the material and section on the ascending segment of the movement because most blades have teeth oriented upwards, which results in the appearance of chips and bites in the material, on the side that is oriented towards the ceiling. For this reason, experienced craftsmen always mark, before starting work, the good face of wood or chipboard and place it on the floor.
However, there are also versions of inverted blades, in which the penetration of the teeth into the material and the actual cutting takes place on the return stage, when the blade moves from top to bottom. In this case, the material is positioned facing the ceiling.
Test the oscillation level before sectioning
The saw blade cuts by vertical movements, from top to bottom or vice versa, but also by moving horizontally, forward, the component called oscillation and which can, in most models, be activated or not, or set on May many speed levels.
In essence, the faster the edge oscillates, the faster you will move forward, because this action completes the pushing movement of the device made by your hand. At the same time, the shorter working period is accompanied by a lower cutting precision, justified otherwise, taking into account that only a part of the feed is controlled by you and the travel speed is higher.
It is therefore recommended to use high levels of oscillation only when working with coarse and simple cuts, which do not require very good accuracy, and to resort to a slower pace or even to stop the oscillation, if you have to follow a more complicated profile. .
Always test these settings on a piece of scrap of the same material you are going to work on, before starting sectioning on the product itself.
Use the drill for the first holes
Among the projects that you will be put in the situation to realize can be included the cutting of a segment from chipboard, MDF or wood, exactly from the center of the material. How do you get there with the saw blade? Simple. Use the drill and make two holes, slightly larger than the canvas, in the opposite corners of the profile and then start cutting.
Secure the metal sheets using the chipboard
If you are interested in pendulum saws or you already have one, you probably already know that these tools can also be used to cut thin sheets of metal. The problem with this type of material is that the hard and elastic structure and the reduced thickness make the metal sheet vibrate harder and tend to bend, being harder to fix on the workbench.
A trick proposed by specialists is to buy two thin chipboard plates (a thickness of 5-7mm is enough) between which to insert the metal sheet, obtaining a kind of sandwich. Then fix the whole workbench combination and start cutting quietly.
Choose the blade carefully for each project
As a basic rule, it is good to know that the bigger the teeth, the less clean and aggressive the cut will be. The width of the sectioning blade influences the ease with which it can be used to follow curved lines. The thinner it is, the tighter you will be able to follow, and the best options for cuts of this type are the options with teeth on both sides of the blade.
It is equally important to use the correct blades for each type of material. A wood version used on metal will grind quickly, without giving you too good results. Look in stores for the right options for each project you start.
Great attention to ceramics
Yes, you can also use the saw to precisely cut the tiles or tiles for the corners or to frame the foot of the sink or the toilet. But it is a sensitive material, which requires increased attention and special blades, so go through some well-documented tutorials before you start working.
