Table Saws: What are they Used For?
A table saw is a tool used to cut wood. They have been around since ancient times. Most of them were made from stone or metal, but nowadays most of them are manufactured with modern technology. Table saws come in various sizes and shapes, some are designed for general purpose while others are specifically designed for cutting specific materials such as lumber, veneer, etc.. Table saws are useful tools that can be used for many different purposes. Some of the common uses include:
Cutting small pieces of wood into smaller pieces (sawing) Cutting large pieces of wood into smaller pieces (cutting) Trimming boards so that they fit together perfectly (trimming) Sanding and polishing rough surfaces Cut out shapes and details in woodwork Cut out patterns in woodwork
How to Safely Use a Table Saw?
Safety is very important when using any type of power tool. If you do not take proper precautions, then your life could be at risk. When it comes to using a table saw, there are certain things that need to be taken care of before starting to work with one. These steps will ensure that you will not get hurt doing these tasks:
Always wear eye protection when working with a table saw! Do not touch the blade directly!
You can seriously hurt yourself. The table saw blade rotates at a very high speed and cutting your fingers is very easy to do. You could lose some fingers or even worse, lose your entire hand. Always use a “push-stick”. A push-stick is a small piece of wood that prevents you from contacting the table saw blade. Always use a push-stick when cross-cutting. Do not reach over the table saw blade! You can seriously hurt yourself if the wood stock moves while the saw blade is spinning. Always use a fence when cross-cutting to ensure that your boards remain in place. Never attempt resawing on a table saw. It is dangerous and can cause serious injury. Do not place your hands under a board while cutting. The table saw blade could grab the board and kickback causing it to catapult back at you. This can result in serious injury or even death.
How to Cut Wood With a Table Saw?
To be able to cut wood with a table saw correctly, you must first understand how the tool works. When a board is placed on the table and the saw blade is turned on, it will not cut immediately. The teeth of the saw blade will first grab the wood and hold it in place while the blade spins. After a few seconds, when the table reaches a certain speed then the blade will start to cut through the stock.
You can determine if the board is going to be cut by gently pushing on it with your hands. Do not force it or apply too much pressure, just a slight amount will do.
If you feel that the teeth of the blade are grabbing the wood then you know that you can start cutting.
Once you get the feel of the saw, then it will be much easier for you to cut wood correctly. You just need to remember these few simple steps and you should be able to do it:
Attach the blade that you intend to use. Make sure it is the correct type and size for the job that you intend to do.
Each blade is designed for a specific purpose so make sure that you select the correct one.
Make sure the table is parallel to the ground. You can do this by placing a carpenter’s square against it.
It should be exactly 90 degrees to the ground. If not, you can adjust the legs at the bottom to equalize the gaps on each side of the table.
Make sure that any removable extensions are secure on the sides of the saw table. If they are wobbly then they will not provide support for your work piece.
Turn on your table saw and allow it to reach its maximum speed. This is usually around 5000 RPM.
Do not place your hand near the blade to feel if it is spinning. Even if it isn’t moving, there can be a “wind” that can cause cuts and abrasions.
Place your work piece into position on the table. Make sure that it is pushed all the way forward towards the blade.
Bring the fence over your piece and lock it into position.
