The maximum amount of material that can be removed per pass on the jointer is:
Correct Answer
A. 1/16"
Explanation
The correct answer is 1/16". The jointer is a woodworking tool used to flatten and smooth the surface of a piece of wood. It is designed to remove a small amount of material with each pass, typically around 1/16" in order to achieve a smooth and even surface. Removing more material per pass can result in an uneven surface and can be unsafe. Therefore, the maximum amount of material that can be removed per pass on the jointer is 1/16".
2.
When jointing edge stock your hands should be located:
Correct Answer
B. Protected by a push stick and/or block.
Explanation
When jointing edge stock, it is important to protect your hands by using a push stick and/or block. This is because jointing involves passing the stock over blades, which can be dangerous if your hands are directly over them. By using a push stick and/or block, you can maintain a safe distance from the blades while still being able to guide the stock through the jointer. This helps to prevent any potential accidents or injuries that could occur if your hands were in close proximity to the blades.
3.
What is generally excessive position of a jointer operator?
Correct Answer
A. Stand in a balanced position and ready to walk the board through.
Explanation
The generally excessive position of a jointer operator is standing right in the middle next to the rotating blade. This position is dangerous as it puts the operator at risk of coming into contact with the blade, which can cause serious injury. It is important for the operator to stand in a balanced position and be ready to walk the board through, while also maintaining a safe distance from the blade.
4.
When jointing the face of stock hands your should be located:
Correct Answer
D. Protected by a push block.
Explanation
When jointing the face of stock, your hands should be protected by a push block. This is because when jointing, the stock is fed into the blades of the jointer, and there is a risk of the stock being pulled through the blades, potentially causing injury to your hands. By using a push block, you can safely guide the stock through the jointer without putting your hands in direct contact with the blades. This ensures that your hands are protected from any potential accidents or injuries.
5.
Stock less than 12" in length:
Correct Answer
B. Must never be jointed.
Explanation
Stock less than 12" in length must never be jointed. Jointing involves running a piece of wood along a jointer to create a flat, smooth surface. However, when the stock is less than 12" in length, it becomes difficult to safely and effectively joint the wood. The short length can make it unstable and increase the risk of accidents. Therefore, it is best to avoid jointing stock that is less than 12" in length.
6.
When should you make a fence adjustment to the jointer?
Correct Answer
A. Before turning on the power.
Explanation
Before turning on the power is the correct answer because making a fence adjustment to the jointer while it is running or after turning on the power can be extremely dangerous. The jointer's spinning blades can cause serious injuries if the fence is not properly adjusted before the machine is turned on. Therefore, it is crucial to ensure that the fence is correctly set before powering on the jointer to avoid any accidents or injuries.
7.
When jointing long pieces of stock it is safest to:
Correct Answer
D. Have a helper or roller stand to support one end.
Explanation
When jointing long pieces of stock, it is safest to have a helper or roller stand to support one end. This is because jointing involves running a piece of wood along a jointer, which can be difficult to do alone, especially with long pieces of stock. Having a helper or roller stand to support one end ensures that the piece remains stable and prevents it from drooping or causing any accidents. This additional support helps to maintain control and accuracy during the jointing process, making it safer for the person operating the jointer.
8.
The purpose of adjusting the fence is to:
Correct Answer
D. All of the above.
Explanation
Adjusting the fence serves multiple purposes. Firstly, it allows for jointing a bevel, which means creating a beveled edge on a board. Secondly, it enables the utilization of different parts of the blade, depending on the desired cut. Lastly, adjusting the fence accommodates surfacing the face of a board, which involves planing or smoothing the surface to make it even. Therefore, the correct answer is "All of the above" as adjusting the fence serves all these purposes.
9.
In you which direction should you run the wood on the jointer?
Correct Answer
B. With the grain.
Explanation
When using a jointer, it is recommended to run the wood with the grain. This helps to ensure a smooth and even surface by reducing tear-out and minimizing the risk of splintering. Running the wood across the grain, especially if it is wider than 12 inches, can lead to uneven cuts and potential damage to the wood. Therefore, the correct direction to run the wood on the jointer is with the grain.
10.
The thinnest that your stock can be to be safely jointed is:
Correct Answer
C. 5/8"
Explanation
To safely joint stock, it needs to have a certain thickness to provide stability and strength. The thinnest option provided, which is 5/8", is the minimum thickness that can be safely jointed. Thinner options like 1/4" or 1/2" would not provide enough stability and may not hold the joint securely. The thickest option, 7/8", would be unnecessarily thick and could add unnecessary weight and bulk to the joint. Therefore, 5/8" is the correct answer.
