What safety gear is needed when using an electric sander?

• Eye protection

• Eye and Ear protection

• Ear and Ear protection and a face mask for saw dust.

• No protective gear is necessary

Answer explanation

Using an electric sander generates noise and sawdust, making ear protection essential to prevent hearing damage and a face mask necessary to avoid inhaling harmful particles. Thus, ear protection and a face mask are required.

What are 3 things that can happen when you apply too much pressure when using an electric sander?

Answer explanation

Applying too much pressure with an electric sander can lead to uneven sanding, overheating the sander, and damaging the material being sanded. These issues can compromise the quality of the finish and the tool's lifespan.

Sandpaper is a key tool in professionally finishing most projects. Select the false answer about Sandpaper.

• When selecting sandpaper you would start with the larger number and finish with the lower number.

• The grit number represents how many sand pebbles it takes to fill up a square inch.

• The smaller the grit number the larger the sand pebble and the more rough or abrasive.

• There is special sandpaper for wet applications, for example when you do a wet sand with oil.

Answer explanation

The false statement is that you start with the larger grit number. In fact, you begin with the lower number (coarser) and progress to the higher number (finer) for a smooth finish.

Sanding with the wood grain is only important when using a strong grit from 60-120ish.

• If you don't push that hard when sanding you wont leave scratch marks so it doesn't really matter.

• True: As the sand grit gets smaller, it leaves fewer scratches, so sanding with the wood grain is less important.

• False: Always sand with the wood grain to get the best, clean, smooth results with no scratch marks in your woods final finish.

Answer explanation

Sanding with the wood grain is crucial for achieving a smooth finish. Even with finer grits, sanding against the grain can leave visible scratch marks, compromising the final appearance of the wood.

With every tool, it is very important to do a pre-check.

What are you checking for when you do an electric sander pre-check?

Select the answer that does not apply.

• Make sure the power cord is firmly connected to the tool and has no weathering along the cord.

• Look at the tool to make sure there are no obvious parts that are broke or loss.

• Make sure the tool looks like new, if you want to be the best you will only work with the best.

• Turn the tool on and listen to the how it runs for a few seconds. If something sounds off let the teacher know.

Answer explanation

The correct choice is about the tool looking new, which is not a pre-check requirement. Pre-checks focus on safety and functionality, not aesthetics. The other options address important safety checks.

When using an electric sander, which of the following is not a recommended safety practice?

• Wearing loose clothing that can get caught in the sander.

• Using a dust mask to avoid inhaling sawdust.

• Ensuring the workpiece is securely clamped before sanding.

• Checking the sander's power cord for damage before use.

Which of the following statements about sandpaper grit is incorrect?

• The higher the grit number, the finer the sandpaper.

• Sandpaper with a grit number of 40 is coarser than one with a grit number of 100.

• Grit numbers indicate the size of the abrasive particles on the sandpaper.

• All sandpapers are suitable for both dry and wet sanding applications.

What is the primary purpose of using progressively finer grits of sandpaper?

• To remove more material quickly.

• To achieve a smoother finish on the surface.

• To increase the speed of the sanding process.

• To reduce the amount of dust produced.

Which of the following is not a recommended practice when using a power drill?

• Using the drill at its maximum speed for all materials.

• Ensuring the drill bit is securely fastened before use.

• Wearing appropriate safety gear, such as goggles.

• Checking the drill's battery charge before starting.

Answer explanation

Using the drill at its maximum speed for all materials is not recommended, as different materials require different speeds for optimal performance and safety.
