All About Scraping And Cutting

Cutting and scraping

May both require sanding
Should never be used on spindle-turned objects
Are both hard on tools so you should use only shear scraping
None of the above

Correct Answer

A. May both require sanding

Explanation

Cutting and scraping are both techniques used in woodworking that may require sanding afterwards. While cutting involves removing material with a sharp tool, scraping involves using a scraping tool to smooth the surface. Both techniques can leave rough edges or uneven surfaces that may need to be sanded for a smooth finish. Therefore, the correct answer is that cutting and scraping may both require sanding.

Scraping

Is done with scrapers that can be round or square or diamond-point or angled
Is easy to learn
Is best when using scrapers that are heavy, which helps make the cut more stable
All of the above

Correct Answer

A. All of the above

Explanation

The correct answer is "All of the above". This means that all the statements mentioned in the question are true. Scraping can be done with scrapers of different shapes such as round, square, diamond-point, or angled. It is also easy to learn. Additionally, using heavy scrapers helps to make the cut more stable, which is considered the best approach. Therefore, all the given statements are correct.

One advantage of using a scraper is

You never have to learn how to use the cutting method
You can remove minute amounts of wood in a specific area of a turning
Scraping tools always remain sharp
A & B

Correct Answer

A. You can remove minute amounts of wood in a specific area of a turning

Explanation

Using a scraper allows you to remove small amounts of wood in a specific area of a turning. This is advantageous because it provides precise control over the shaping and smoothing of the wood, allowing for intricate details and fine adjustments. Unlike cutting methods, which may require more skill and technique to achieve the same level of precision, a scraper simplifies the process and allows for greater accuracy in woodworking. Additionally, scrapers can be easily sharpened or replaced when they become dull, ensuring that the tool remains effective throughout the woodworking process.

The bevel angle for a scraping tool

Should be between about 30 and 60 degrees
Should be close to 90 degrees
Is of no consideration
Is correct when it arrives from the store

Correct Answer

A. Should be between about 30 and 60 degrees

Explanation

The correct answer is "should be between about 30 and 60 degrees." This is because a bevel angle within this range allows the scraping tool to effectively remove material while minimizing the risk of the tool digging in or causing damage. A bevel angle that is too small may result in inadequate cutting, while a bevel angle that is too large may make the tool difficult to control. Therefore, a bevel angle between 30 and 60 degrees strikes a balance between cutting efficiency and control.

Cutting

Is faster than scraping
Is done with gouges and skew chisels
Leaves the fibers of the wood in better shape than scraping does when initial cuts are made
All of the above

Correct Answer

A. All of the above

Explanation

Cutting is indeed faster than scraping as it involves removing material from the wood more efficiently. It is done with gouges and skew chisels, which are specifically designed for cutting wood. When initial cuts are made, cutting leaves the fibers of the wood in better shape compared to scraping, which can cause more damage to the wood fibers. Therefore, all of the given statements are correct.

Cutting should be employed as much as possible when turning wood. The exception to this

Is when the tool needs to be moved uphill on the cove of a spindle
Is when you are teaching beginners
Is when you are going to paint the wood
None of the above

Correct Answer

A. Is when you are going to paint the wood

Explanation

Cutting should be employed as much as possible when turning wood because it helps to create clean and smooth surfaces. However, when you are going to paint the wood, it is not necessary to focus on achieving a perfect surface finish because the paint will cover any imperfections. Therefore, in this specific case, cutting can be minimized or avoided to save time and effort.

The steepness of the bevel on a gouge is of some importance for achieving a good cut and for

Ease of sharpening
The look of the tool
Controlling the tool when cutting
Keeping your tool cool while it cuts

Correct Answer

A. Controlling the tool when cutting

Explanation

The steepness of the bevel on a gouge is important for controlling the tool when cutting. A steep bevel allows for better control and precision while using the gouge, as it helps to guide the tool along the desired path and prevent it from slipping or veering off course. It also allows for better maneuverability and responsiveness, making it easier to make accurate cuts and shape the material as intended. Therefore, the steepness of the bevel plays a crucial role in controlling the tool effectively during cutting tasks.

Shear scraping

Can be done with scrapers and with gouges
Achieves a very fine, controlled cut
Is sometimes the only method for accessing difficult-to-cut areas
All of the above

Correct Answer

A. All of the above

Explanation

Shear scraping is a technique that can be performed using both scrapers and gouges. It allows for a very fine and controlled cut, making it suitable for achieving smooth and precise finishes. Additionally, shear scraping is often the only method that can be used to access and cut difficult-to-reach areas. Therefore, the correct answer is "All of the above."

To shear scrape with a bowl gouge, the profile of the gouge should be

Straight across
That of a fingernail grind, making sure the sides are sharp
You should never shear scrape with a bowl gouge
Closer to what you would use if you were not sure what it should be

Correct Answer

A. That of a fingernail grind, making sure the sides are sharp

Explanation

The correct answer is that of a fingernail grind, making sure the sides are sharp. Shear scraping with a bowl gouge requires a specific profile, which is similar to a fingernail grind. This profile allows the gouge to smoothly cut the wood fibers at a shear angle, resulting in a clean and smooth surface. It is important to ensure that the sides of the gouge are sharp to maintain efficient cutting and prevent tear-out.
