A Safety Quiz On The Table Saw Jointer!

Explanation
Removing or locking the safety guard of a jointer in an open position is not safe. The safety guard is designed to protect the user from the rotating cutterhead and other moving parts of the jointer. By removing or locking the safety guard, the user is exposing themselves to potential hazards and increasing the risk of accidents or injuries. It is important to always keep the safety guard in place and properly functioning while operating the jointer to ensure a safe working environment.

Explanation
The statement is true because a jointer is a woodworking tool used to straighten and smooth the edges of lumber. In order for the jointer to effectively work, the lumber must have a minimum thickness of 1/4 inch. Anything thinner than that may not be properly supported and could result in uneven or unsafe results.

Explanation
The statement is true because loose knots or other defects in lumber can weaken its structural integrity. When joining lumber, it is important to ensure that the wood is free from any defects that could compromise its strength and stability. Loose knots can cause the wood to split or break under pressure, posing a safety risk. Therefore, it is not safe to joint lumber with loose knots or other defects.

Explanation
Applying pressure directly over the knives of the jointer is not safe because it can cause the stock to vibrate. Vibrations can lead to instability and potentially dangerous situations. It is important to apply pressure on the infeed and outfeed tables of the jointer instead, ensuring a stable and secure operation.

Explanation
It is not safe to joint the end of a board on a jointer. Jointers are designed to flatten and straighten the faces of boards, not the ends. Attempting to joint the end of a board on a jointer can result in kickback or other safety hazards. It is recommended to use alternative tools such as a miter saw or a table saw with a sled to safely cut and square the ends of boards.

Explanation
The out feed table of the jointer should be level with or slightly higher than the in feed table. This is because the out feed table supports the wood as it exits the jointer, ensuring a smooth and even cut. If the out feed table is lower than the in feed table, it can cause the wood to dip and result in an uneven cut. Therefore, the statement that the out feed table should be 1/16 inch lower than the in feed table is false.

Explanation
The statement says that the edge of a 3/4 x 4" piece of plywood can be pushed through the jointer. However, this is not true because a jointer is a woodworking tool used for flattening and straightening the edges of a board. It is not designed to handle the thickness of a 3/4 inch plywood. Therefore, the correct answer is False.

Explanation
The correct answer is 1/16. The jointer is a woodworking tool used to flatten and smooth the surface of a wooden board. In one pass, the jointer can remove a maximum amount of 1/16 of an inch of wood. This means that with each pass, the jointer will shave off a thin layer of wood measuring 1/16 of an inch in thickness, resulting in a smoother and more even surface.

Explanation
The stock must be at least 10 inches long when using the jointer because this is the minimum length required to safely and effectively pass it through the jointer and achieve the desired results. Using shorter stock may not provide enough surface area for the jointer to properly flatten or square the wood.

Explanation
The correct answer is 3. When using a jointer, it is important to maintain at least a 3-inch margin of safety. This means that you should keep your hands, fingers, and other body parts at least 3 inches away from the spinning blades to avoid any potential accidents or injuries. By maintaining this margin of safety, you can ensure a safer and more efficient operation of the jointer.

Explanation
When using a jointer, it is important to use a push stick when the part being worked on is less than 3 inches. This is because a push stick provides a safe and controlled way to guide the material through the jointer while keeping hands at a safe distance from the spinning blades. It helps to prevent accidents and ensures that the user maintains a firm grip on the material without risking their hands getting too close to the cutting area. Using a push stick is a standard safety practice when operating a jointer.

Explanation
"Kick back" is the correct answer because it accurately describes the action of a board being thrown back out of a machine. The term "kick back" implies a forceful and sudden movement, which aligns with the action of the board being forcefully thrown back. "Kick out" and "throw back" do not convey the same level of force and suddenness as "kick back," making them incorrect options.

Explanation
The safety guard must be used on the table saw at all times for most standard operations. The safety guard helps to protect the user from potential accidents by covering the blade and preventing any contact with it. It acts as a barrier between the user and the spinning blade, reducing the risk of injuries. By using the safety guard, the chances of accidental contact with the blade are significantly reduced, ensuring a safer working environment.

Explanation
Cutting a board free hand on a table saw is dangerous because it requires holding the board without any support or guide, increasing the risk of the board moving or twisting during the cut. This can result in uneven or inaccurate cuts, potential kickback, and the possibility of injury to the person operating the saw. It is always recommended to use a miter or fence as guides to ensure stability and precision when cutting boards on a table saw.

Explanation
A push stick must be used when ripping boards under 6 inches in width on the table saw. This is because when ripping narrow boards, there is a higher risk of the user's hand being too close to the blade, which can result in accidents and injuries. The push stick allows the user to maintain a safe distance from the blade while still exerting control and pressure on the board being cut.

Explanation
When using a table saw, it is important to never stand directly in line with the blade. This means that you should not position yourself in a way that aligns your body with the path of the blade. Standing in line with the blade can be dangerous as it increases the risk of being hit by flying debris or being injured if the material being cut kicks back. It is recommended to stand to the side or slightly behind the blade to ensure safety while operating the table saw.

Explanation
The fence is used when ripping boards on the table saw. The fence is a guide that can be adjusted parallel to the saw blade, allowing for precise and straight cuts when ripping boards. It helps to keep the board aligned and prevents it from wandering during the cut. The miter guide is used for making angled cuts, and the dado head is a specialized blade used for making dado cuts, not ripping boards.

Explanation
A miter guide is used when cross cutting boards on the table saw. It helps to guide the board at a specific angle, allowing for precise and accurate cuts. The miter guide is typically adjustable, allowing for different angles to be set depending on the desired cut. It is an essential tool for making angled cuts on the table saw.

Explanation
A board that is warped cannot be sawn by any method on the table saw because warping refers to the distortion or bending of the board, causing it to have an uneven or curved shape. This makes it difficult to hold the board securely and accurately against the table saw's surface, resulting in an unstable and unsafe cutting situation. Therefore, a warped board is not suitable for sawing on a table saw.

Explanation
When using a table saw, it is important to never rip a board that is wider than it is longer. This is because ripping refers to cutting a board lengthwise, and if the board is wider than it is long, it becomes unstable and difficult to control on the table saw. It is safer and more efficient to cut boards that are longer than they are wide.

Explanation
The blade on the table saw should extend approximately 1/16 inch above the board being cut. This is because having the blade extend too far above the board can increase the risk of kickback and accidents. On the other hand, having the blade too low may result in a poor quality cut. Therefore, a small extension of 1/16 inch ensures a balance between safety and a clean cut.

Explanation
It is important to never wear loose clothing while working on a table saw because loose clothing can easily get caught in the saw's moving parts, leading to serious accidents or injuries. Tight-fitting clothing is recommended to ensure safety and prevent any potential hazards.

Explanation
When using a table saw, it is important to maintain a minimum safety margin of 6. This means that you should keep a distance of at least 6 inches between your hands and the blade while operating the saw. This safety margin is necessary to prevent accidental contact with the blade, reducing the risk of injury. By maintaining a sufficient distance, you can ensure your safety and minimize the chances of accidents or mishaps while using the table saw.

Explanation
When using the new Saw Stop Table Saw, it is not okay to use wet or treated lumber. Wet lumber can cause the blade to bind or kickback, leading to accidents. Treated lumber contains chemicals that can damage the saw's blade and other components. It is important to use dry and untreated lumber to ensure safe and efficient operation of the table saw.
