Throat Size
The WEN 3921 Scroll Saw has a 16-inch throat size, which means it can cut through materials up to 2 inches thick. The throat size is the distance between the blade and the rear of the saw’s arm and determines the maximum width of the material that can be cut.
The larger the throat size, the bigger the material that can be cut. The 16-inch throat size of the WEN 3921 provides plenty of space for cutting larger materials, making it a versatile tool for woodworking projects.
Adjustments
It offers many adjustments that allow you to customize its performance to your needs.
One of the main adjustments is the variable speed control, which allows you to adjust the speed of the blade from 400 to 1600 strokes per minute. This matches the blade speed to the material being cut, ensuring the cut is clean and precise.
The saw’s table is also adjustable and can be beveled up to 45 degrees to the left for angled cuts. This provides flexibility for cutting materials at different angles to create intricate designs and shapes.
The saw’s blade adapter features a thumb screw mechanism for tool-free blade changes, making it easy to switch blades without requiring any additional tools. This saves time and effort during the cutting process to make quick adjustments as needed.
Variable Speeds
The WEN 3921 Scroll Saw has a variable speed control that adjusts the blade speed from 400 to 1600 strokes per minute. Having variable speed control is a crucial feature for a scroll saw, as different materials require different blade speeds for optimal performance.
For example, softer woods like pine require slower blade speeds, while harder woods like oak require faster blade speeds. By adjusting the blade speed, you can achieve cleaner and more precise cuts.
The saw’s variable speed control is easy to use, with a simple knob that adjusts the blade speed to your desired level.
Cutting Performance
The WEN 3921 Scroll Saw is a high-performance tool with excellent cutting performance due to its two-directional blade design that allows for infinite ripping capacity, while the variable speed control enables users to match the blade speed to the material being cut.
Ease of Use
This WEN 3921 saw is designed for ease of use, making it ideal for both beginner and experienced woodworkers. Its variable speed control, easy-to-use blade adapter, spacious table, and air pump for clearing sawdust all contribute to its user-friendliness.
Moreover, it is equipped with a built-in work light and a dust port, enhancing both visibility and cleanliness in the workspace. These features contribute to more accurate and precise cuts while reducing the chances of accidents occurring.
Dust Blower
This saw comes equipped with a dust blower that helps to keep the cutting line clear of sawdust and debris.
The dust blower is powered by an air pump that is located underneath the saw’s table. When turned on, the pump blows a steady stream of air onto the cutting line, helping to clear away sawdust and debris as the saw blade moves back and forth.
This feature is particularly useful when working with materials that produce a lot of sawdust or when making intricate cuts that require a clear view of the cutting line.
By keeping the cutting line clear, the dust blower helps to ensure that users can make accurate and precise cuts, reducing the risk of mistakes and accidents.
Extra Features
This WEN 3921 Scroll Saw with Work Light has many extra features that improve its functionality and user-friendliness.
One useful extra feature is the saw’s cast iron base, providing stability and helping to reduce vibration during use. This makes the saw more precise and easier to control, improving the quality of the cuts and reducing the risk of accidents.
We also found that the saw also comes with a foot lock clamp, which helps to hold the material being cut securely in place, reducing the risk of slippage and making more accurate cuts. The clamp [1] is easy to use, with a simple foot pedal that activates the clamp.
Other extra features of the WEN 3921 saw include onboard storage for the included blades, a dust port for easy clean-up, and a flexible work light that can be adjusted to any angle.
Blade Change
This saw has an easy-to-use blade-changing mechanism, like the Wen LL2156. It features a thumb screw blade adapter that allows for quick and easy blade changes without any additional tools.
This saves time and reduces the risk of injury associated with handling sharp blades. To change the blade, you simply loosen the thumb screw, remove the old blade, insert the new one, and tighten the thumb screw.
This user-friendly feature enhances the saw’s functionality and makes it an excellent tool for woodworkers of all skill levels.
Value for Money
The WEN 3921 Scroll Saw is a great tool for woodworkers who want high quality at an affordable price.
Its powerful motor and large table can handle thick wood and angled cuts, and its versatile features, such as two-directional blade operation and variable speed control, make it perfect for various scroll saw projects.
Additionally, its ease of use is improved by features such as the blade adapter, dust port, air pump, and foot lock clamp. The saw also comes with a 2-year warranty for added peace of mind. Overall, the WEN 3921 offers excellent value for money.
WEN 3921 vs 3920 vs 3922
The WEN 3921, 3920, and 3922 are three models of scroll saws produced by the same manufacturer, WEN.
While all three models are similar in design and functionality, there are some key differences between them that are worth noting.
Key Differences
WEN 3921, 3920, and 3922 are three scroll saw models with some key differences.
The WEN 3920 and 3921 offers the same variable speed control from 400 to 1600 strokes per minute, while the 3922 has a variable speed from 550 to 1600 strokes per minute.
This variable speed control allows you to adjust the speed of the blade to suit the specific needs of your project.
The WEN 3921 and 3922 both feature a dust port that can be connected to a vacuum to help keep the work area clean, while the 3920 does not have a dust port.
This is an important feature for those who value a clean workspace and want to minimize the amount of dust produced during use.
The WEN 3921 and 3922 feature a thumb screw blade adapter for tool-free blade changes, while the 3920 does not have this feature. This makes it easier to change the blade and adjust to the specific needs of your project.
In addition, it should be noted that the 3921 employs a blade-holding mechanism that allows for two-directional use, making it ideal for pinned blades, whereas the 3922 utilizes a standard blade-holding system that is more suitable for pinless blades.
Finally, the WEN 3921 and 3920 come with a built-in work light, while the 3922 does not have this feature. The work light is particularly useful when working on intricate or detailed projects, providing additional visibility to help you achieve accurate cuts.
