Almost every table saw is delivered with a single pusher. But that's not enough. You need at least a push stick and a push block to provide the correct pressure contacts. Otherwise, your cuts are not straight and you risk a serious injury.
The use of a table saw always carries a certain risk. They move the material towards and through a sharp spinning blade. Depending on how strong your table saw is, the blade rotates between 3,000 and 5,000 revolutions per minute (RPM). Your eyes can not keep up so fast.
When it comes down to it, anything that can cut wood can cut through your soft, fleshy body. Regardless of the risk of injury, there is a risk of you getting a setback, and your cut is not straight. This leads to disappointing results.
Backlash is incredibly dangerous
Warning : The following section explains the dangers of table saws and may make some readers squeamish or restless; We recommend that you proceed to the next section if this describes you.
If you are unfamiliar with the concept of woodworking recoil, you are lucky. A kickback occurs when the rotating saw blade of your table saw grips a piece of material to be cut, lifts it and throws it at high speed. As the blade turns in your direction, the wood is thrown in your direction and can hit you hard enough to hurt you or even kill you.
This is not the only danger from a setback. As the blade pulls the wood onto it, the process also pulls your hands towards the blade. If you are lucky, you have smaller cuts. But it is also possible that you lose your fingers on the spinning blade.
A form of kickback occurs during a longitudinal cut when part of the wood passes the back of the blade. If the material deviates from the rip fence, a corner of the wood may catch the rising teeth of the blade, pulling the wood onto the blade and producing a thrown piece of wood.
The following video shows this type of kickback. Fair warning, the person in the video comes out unharmed (just yet), but it's still scary to see how close she gets to a serious injury.
As the video shows, this setback occurs when your piece of wood drifts away from the rip fence and into the blade path. You can prevent these and other forms of kickback by using suitable safety equipment and technology. The first device is a splitting knife.
If you have recently purchased your table saw, a small piece of metal was installed just behind the blade. In general, you should not remove Dado blades unless they have a specific cause (for example, installing blades). The splitting knife provides a physical barrier to prevent your piece of wood from drifting onto the back teeth of your rotating saw blade.
The second device is a printing block or a printing block in combination with a technique in which three points are applied by pressure. This technique not only protects you but also achieves better cutting results.
Use three pressure points for better, safer cuts.
In a longitudinal section, a board is slid over the table saw while the longitudinal fence is touched to guide the knife. If your board deviates from the rip fence, your cut will be crooked (and a setback may occur).
So, when you pass the wood through the table saw, you want to apply three pressure points, as shown in the picture above. (Note: I raised the blade after the cut to make the image clearer.) The first pressure moves forward. Of course, to cut wood on a table saw, you must move the material towards the blade.
The second is the pressure down. That means the pressure comes from the top of the table saw. Pushing down against the board will prevent the table saw blade from raising your board and throwing at you.
The third is the pressure inside. To avoid kickback and maintain straight cuts, you must apply pressure to the board in the direction of the longitudinal cut. This pressure must be exercised before and not after the table saw blade. If you try to push inwards towards the fence after the saw blade, the freshly cut wood will be trapped, which may result in a kickback.
Maintaining these three points of contact not only gives you a straight cut (because you're driving straight from your rip fence), but also minimizes the risk of kickback. The general idea is that your material moves smoothly across the cutting path without it drifting onto the blade.
You can achieve these three pressure points by using a pusher and a pusher block. Your table saw was probably delivered with a printing block. As long as you use the right technique, it works flawlessly. You should use the push stick for your inward point of contact with the fence.
Next, place your push pad on the board you want to cut and apply even pressure down and forward to move the board through the blade. Keep an eye on the fence to make sure your board does not drift off.
Although theoretically you could use two push rods, you may not get enough pressure down to prevent a setback. With a push stick, focus the back corner of the board down, not over the surface.
Alternatively, you can use a GRR-RIPPER push block instead of a push stick and a push block. It is able to safely provide all three pressure points in a single tool.
No matter what you use, the important thing is to keep your fingers away from the spinning blade. Destroying a push block is much better than the alternative.
The Push Blocks That You Should Buy
Now that you know why you need a push block, it's time to buy one. There are many choices and everything is better than nothing. But here are a few good tips:
A good sliding block: Big Horn 10230 Push Stick
Sometimes you can see how the items are pressed Blocks and push sticks are used interchangeably, and that's the case with the Big Horn 10230 push stick. The critical part is the security features it provides. This includes a spring-loaded tip on the back that sticks out at the end of your board for maximum grip. And a rubberized texture along the bottom increases grip when pushing and moving forward. The closed construction that surrounds your hand should mean that in the event of a defect, the wand is likely to hit your blade against your hands and give you an extra layer of protection.
pack: Safety Woodworking Package
If you want many options, you have coverage with this security package. It not only has table saw friendly push sticks and push blocks, but also push blocks that work with your router table and jointer. Some of the thrust blocks are equipped with a fat gum for a particularly grippy texture. The bright orange color is also very helpful when trying to figure out where in the business the safety equipment has landed. A Grr Ripper 3D sliding block with green knobs.
