What You'll Learn
Adjusting the stroke length
The WEN Electric Engraver allows for variable stroke adjustment, enabling heavy or fine engraving. To adjust the stroke length, you can use the stroke adjustment screw at the back end of the tool. The further you screw it in, the shorter the engraving point's stroke will be, as it limits the travel of the L-shaped armature.
The WEN 21B model appears to have an improved stroke adjustment screw compared to the older WEN Model 21, which had issues with the screw's head breaking off. There is also a WEN 21C model with a revised stroke adjustment.
The WEN 21D model features a depth-adjustment dial that controls the length of the engraver's stroke. This model is also variable speed, allowing for intricate designs.
It is important to note that some users have reported issues with the build quality, noise level, and engraving tip of the WEN 21C model. However, others have found it to be reasonably priced, sturdy, and easy to use, with adjustable engraving speeds.

Repairing a broken stroke adjustment screw
The WEN Model 21 Electric Pencil Engraver is a compact engraving tool that allows users to carve initials, pictures, or other designs into a variety of materials. While it is generally well-constructed, one common issue with this model is a broken stroke adjustment screw. This screw controls the length of the engraving point's stroke, with a shorter stroke allowing for finer engravings.
If the head of the stroke adjustment screw has broken off, it is possible to repair it without replacing the entire screw. One approach is to use the female portion of a binder post, also known as a "Chicago screw," to recreate a handle end on the remaining portion of the screw. This will allow you to continue using the original screw and avoid the need for a replacement.
To address the distorted thread on the broken end of the screw, you can create a thin threading die by sawing through one side of an 8-32 steel hex nut and running a tap through it to remove any burrs. Passing the screw remnant through this die will help clean up the thread, making it usable again.
Alternatively, you can replace the nylon screw with a steel screw and add two nuts behind the spring to adjust the tension. This approach may provide a more durable solution, as nylon screws are relatively soft and prone to damage.
After making the necessary repairs, it is important to test the engraver to ensure that it is functioning correctly. You may also want to consider applying epoxy to the head of the adjustment screw to suppress vibration and make the tool smoother and easier to adjust.

Replacing the nylon screw with a steel screw
The WEN Model 21 Electric Pencil Engraver is a valuable tool for marking tools and other valuable equipment for easy identification and protection against theft. However, one common issue with this engraver is a broken stroke adjustment screw, which can render the tool unusable.
The stroke adjustment screw is a nylon 8-32 screw with a conical end. When it is screwed further in, it limits the travel of the L-shaped armature, resulting in a shorter engraving point stroke. If the head of this screw breaks off, it can be challenging to repair. While it is possible to attempt a repair using the female portion of a binder post (also known as a Chicago screw) to recreate a handle end on the screw remnant, this can be complicated if the screw's thread has been distorted by previous repair attempts.
One solution to this problem is to replace the nylon screw with a steel screw. By using a steel screw and placing two nuts behind the spring, you can adjust the tension and avoid the need for frequent repairs. This method was suggested by a user who successfully repaired their WEN Model 21 Electric Pencil Engraver and shared their experience on a blog.
To implement this solution, you will need to disassemble the engraver by removing two threading screws and a snap-ring. Once you have access to the stroke adjustment mechanism, you can replace the nylon screw with a steel screw of the same size and specifications. It is important to ensure that the steel screw is compatible with the engraver's mechanism and that it can be adjusted to achieve the desired stroke length. After installing the steel screw, you can secure it in place using CA adhesive to make the screw and 'nut' assembly permanent.

Adjusting the engraving speed
Locate the Stroke Adjustment Screw: The WEN Electric Pencil Engraver allows you to adjust the engraving speed by controlling the length of the stroke. Locate the stroke adjustment screw, which is usually found at the back end of the engraver, below the line cord.
Understand the Screw Mechanism: The stroke adjustment screw is typically made of nylon or steel. By screwing it further in, you reduce the travel of the L-shaped armature, resulting in a shorter stroke and finer engraving. Conversely, unscrewing it slightly will increase the stroke length for deeper engravings.
Make Gradual Adjustments: When adjusting the stroke length, make small, gradual adjustments to achieve the desired engraving speed and depth. Fine-tuning the screw allows for precise control over the engraving process.
Consider the Material: Different materials may require varying engraving speeds. For example, when engraving on hard metals, you may need to adjust the speed differently than when working on softer materials like wood or plastic.
Use the Depth Adjustment Dial: Some WEN engravers feature a 5-position depth adjustment dial. This dial lets you control the length of the stroke for both fine and deep engravings without needing to adjust the screw. Play around with the dial settings to find the optimal speed for your project.
Practice on Similar Surfaces: Before starting your actual project, practice adjusting the engraving speed on similar surfaces. This will help you get a feel for the tool and ensure that you've set the correct speed for your intended engraving depth and material.
By carefully adjusting the engraving speed, you can create customized and precise engravings on a variety of materials with your WEN Electric Pencil Engraver. Remember to refer to the user manual or seek support from the WEN customer helpline if you need further assistance.

Using the engraver to mark tools
Marking tools with an engraver is a great way to ensure easy identification and protection against theft. The WEN Electric Engraver is a popular tool for this purpose, with the ability to create both fine and deep engravings on a variety of materials, including plastic, ceramic, leather, metal, glass, and wood. Here are some tips for using the engraver to mark your tools:
Before you begin, ensure that your engraver is adjusted to the correct settings. The WEN Engraver features a 5-position depth adjustment dial that allows you to control the length of the stroke for different engraving depths. This is particularly important when marking tools, as you may want to create deeper marks for parts exposed to harsh environments or shallower marks for aesthetic purposes.
When marking your tools, it's important to consider the placement of your engravings. For durability and easy identification, choose a spot on the tool that is not exposed to excessive wear and tear. Discreet markings, such as on the inside of a tool, can also be effective in preventing theft while maintaining the tool's aesthetics. Additionally, consider marking in multiple visible spots to increase the chances of identification if the tool is stolen.
The WEN Engraver comes with a two-piece stencil set that includes letters, numbers, and symbols, allowing you to create a variety of designs. You can use these to engrave your name, initials, or company name, or any other unique markings that will help identify your tools. If you want your markings to stand out even more, you can fill the engraved letters with a paint marker or consider painting your tools entirely.
When engraving your tools, it is good practice to record the model and serial number of each tool. This information can be crucial for identification and recovery in the event of theft. Additionally, consider marking parts' relationships with one another to ensure that you can easily reassemble any disassembled tools.
Always prioritize safety when using an electric engraver. Wear appropriate protective gear, such as safety goggles and gloves, to safeguard against any debris or sharp edges created during the engraving process. Additionally, ensure that you are working in a well-ventilated area to mitigate the risks associated with inhaling debris or dust.
