RVHS Planer Test

Safety goggles are necessary to protect the eyes from any potential flying debris or particles that may be produced while using a planer. This is important to prevent any eye injuries or accidents that could occur during the operation of the planer. Therefore, it is true that safety goggles are required to use the planer.

Looking into a planer while it is running is not safe. Planers are powerful machines used for cutting and shaping wood, and they have sharp blades that rotate at high speeds. Looking into a running planer can result in serious injuries, including cuts, lacerations, or even the loss of fingers or hands. Therefore, it is important to always prioritize safety and avoid looking into a running planer.

The correct answer is "all of these". When planning to check the stock, it is important to consider all the mentioned factors such as nails, loose knots, paint, sand, and dirt. This ensures that the stock is in good condition and suitable for use. By checking for nails, one can ensure that there are no sharp or protruding objects that may cause harm. Loose knots should be inspected to avoid any structural weaknesses. Paint and sand/dirt should be examined to ensure cleanliness and smoothness of the stock. Therefore, considering all these factors is crucial for proper stock selection.

When the board sticks, it is important to turn off the machine to prevent any accidents or injuries. This will stop the blade from spinning and reduce the risk of any further damage. Once the machine is turned off, it is safe to address the issue by letting the blade stop completely and then lowering the table. This sequence of actions ensures safety and prevents any potential harm.

Feeding against the grain tears and chips the work. When working with wood, it is important to follow the direction of the grain to prevent any damage or imperfections. Feeding against the grain causes the wood fibers to be torn and chipped, resulting in a rough and damaged surface.

Before starting the machine, it is important to set the table height to the thickest part of the board. This ensures that the machine will be properly adjusted to handle the thickest section of the material being worked on. Additionally, the table should be raised slightly, about 1/16 of an inch or less, to provide a small clearance for smoother operation.

Putting the red lever near the on/off switch in the up position is the correct answer because it specifically states that this action will put the planer in neutral. By doing so, it relieves the pressure off the drive belts, which helps to prevent any potential damage to the machine.

The correct answer is 12". This is because the planer requires a minimum length of 12" to safely run the board through. Running a shorter board through the planer could result in instability and potential damage to the board or the planer itself.

When planing a board to 1/4" thick, it is important to use a backer board. A backer board is a flat and stable surface that is placed underneath the board being planed. It helps to prevent tear-out and splintering of the wood by providing support and stability during the planing process. By using a backer board, the woodworker can achieve a smooth and even surface while reducing the risk of damaging the wood.

When adjusting the table height, the maximum amount you can turn the handle is 1/4 turn. This means that you can rotate the handle by one quarter of a full turn. This suggests that the handle has a limited range of motion and can only be turned a certain amount before reaching its maximum position.

When planning, it is important to ensure that the downside of the material is surfaced on the jointer. This means that the jointer is used to flatten and smooth the bottom surface of the material, ensuring that it is level and free from any imperfections. By surfacing the downside on the jointer, you can achieve a flat and even surface, which is essential for accurate and precise woodworking.
