Ps:1 Router Table Safety Exam

Explanation
It is important to wear a respirator when working on a router table because the machine produces a lot of dust and debris. These particles can be harmful if inhaled, causing respiratory problems or irritation. Wearing a respirator helps to filter out these particles and protect the person working on the router table.

Explanation
The explanation for the correct answer "True" is that it is important to check that the switch is in the off position before plugging the router into the outlet. This is a safety precaution to prevent any potential electrical hazards or damage to the router. By ensuring that the switch is off, it reduces the risk of electrical shock or short-circuiting when connecting the router to the power source.

Explanation
The correct answer states that for control and safety, your hands and fingers should be kept as far away from the revolving bit as possible, with a minimum distance of 3 inches. This ensures that there is enough distance to prevent any accidental contact with the bit, reducing the risk of injury. While it is important to use a push stick on the router table, this answer specifically addresses the distance requirement for hands and fingers.

Explanation
When shaping narrow stock, it is important to keep your hands away from the bit to avoid any accidents. Using feather boards and clamps helps to secure the stock in place, preventing any movement or slipping during the shaping process. Additionally, using a push block allows for better control and grip on the stock, ensuring a smooth and safe shaping experience. Therefore, all of the above options are necessary precautions to take when shaping narrow stock.

Explanation
The statement suggests that one should clamp a block of wood to the fence above the bit with clearance for their stock. This is a correct statement as it is a common practice in woodworking to use a block of wood to provide support and stability to the stock being worked on. By clamping the block of wood to the fence above the bit, it ensures that the stock remains in place and prevents any potential accidents or mishaps while working with the tool.

Explanation
The statement suggests that in order to see the profile of the fence after the router machine has been turned on, the halves of the fence should touch the router bit. However, this is not true. The profile of the fence can be seen even if the halves of the fence do not touch the router bit. The router bit will still shape the edges of the fence, regardless of whether the halves are touching it or not.

Explanation
Using a miter gauge and clamp for end grain shaping is a correct and effective method. When shaping the end grain of a workpiece, it is important to have proper control and stability. A miter gauge helps in guiding the workpiece accurately and maintaining a consistent angle while shaping. Clamping the workpiece securely ensures that it does not move or shift during the shaping process, resulting in more precise and desired outcomes. Therefore, using a miter gauge and clamp for end grain shaping is a recommended approach.

Explanation
The statement is false because it states that the only foreign objects in the stock to be concerned with are nails. This implies that there are no other foreign objects to be concerned with, which may not be true. There could be other foreign objects such as screws, staples, or other debris that can cause damage or harm. Therefore, it is important to be cautious and aware of all potential foreign objects in the stock, not just nails.

Explanation
It is important to never reach under the table while the router is running because it can be extremely dangerous. The router has sharp blades that rotate at high speeds and can cause severe injuries if someone's hand or fingers get caught in them. Therefore, it is crucial to always turn off the router and wait for it to completely stop before reaching under the table to avoid any accidents.

Explanation
When removing the fence and using a starting pin and a bearing on the bit, freehand cuts are allowed. This means that the cuts can be made without the assistance or guidance of a fence, as long as the starting pin and bearing on the bit are used. Therefore, the statement is true.
