What is a Worm Drive Saw and How Does it Work?
What is a worm drive saw?
There are various types of saws that are used in building and construction. For example, the common types include hacksaw, handsaw, jigsaw, table saw, and circular saw. A worm drive saw is a type of circular saw that is used in renovation and framing jobs. The motor of the worm drive saw is located on the front of the engine.
The blade of the saw has a worm-like shape; hence the name worm drive saw. The worm-like apparatus helps structure in a manner that makes the worm drive saw suitable for cutting thick and difficult materials. It is also significant to note that the worm drive saw was invented in Louisiana to help the sugarcane workers in harvesting.
This is because it worked faster and effectively than machetes. Since many people don’t know what is a worm drive saw or its’ purpose, using it correctly can be quite tricky and complicated. Therefore, it is essential to learn techniques of using the saw safely and effectively to produce great results.
How Does a Worm Drive Work?
1. Adjust the Blade Length and Bevel Angle
Before you start working with a worm drive, saw, ensure that you adjust the bevel angle and the length of the blade. The tool that will help in these adjustments is a square. You will hold the particular square against the worm saw’s baseplate and confirm the angle of the blade. Ensure that you set the bevel angle to a reasonable place that will make the saw work effectively.
2. Set the Depth of the Blade
After setting the blade length and bevel angle, the next step is to adjust the depth of the blade to a spot where the material being cut is cleared on the underside. It is essential to ensure that the blade’s depth is not low that necessary.
This is because it might cause kickback, or might increase the heat, thus destroying the work. Furthermore, a large part of the blade will remain unguarded, which is quite harmful.
3. Stay Connected
After adjusting both the angle, length, and depth of the worm saw, it is essential to ensure that the worm saw is firmly connected to a power source. However, keeping the particular electrical cables of the saw connected might be quite tricky. Hence, when they tend to be loose, you can improvise by safely tying a firm knot that will keep the cords together.
Let the weight of the saw do much of the work.
4. Tilt the Studs for Easy Cutting
Ensure that you keep your body at a safe distance from the saw. The hand that holds the particular lumber should also tilt it farther from your body. This will ensure a safe and gradual progression of cutting. Besides, to free your arm from stress, ensure that the saw cuts downhill.
5. To Save Effort, Cut from the Ground
While working with a worm saw, it is essential to save effort. Hence, you should hold the work on your ankle, use your free hand for tilting the angle of the studs, and let the saw cut use gravity to cut the work downhill.
6. To Align the Cut, Utilize the Saw’s Baseplate
It is essential to ensure that your cut is well aligned. Hence, using the saw’s baseplate for alignment purposes is fundamental. The baseplate has particular indents that show the position of the blade’s cut.
For bevel and plunge cuts, lift the blade guard.
7. For Plunge Cuts, Brace the Baseplate
Before you start cutting, ensure that you brace the fore-edge of the baseplate’s full length against the surface that you are working on. To cut, pull back the guard of the blade, draw the trigger, and lower the blade with uniform pressure.
8. Use two Hands to Make Bevel Cuts
The hand on the trigger should be the one that controls the progression of the cut. The other hand has two crucial tasks. Steadily guiding the worm drive saw’s front, and pulling back the saw’s blade guard to ensure the cutting is smooth.
These particular guidelines will help you understand what a worm drive saw is and how to use it safely and effectively. Also, it is essential to note that the simplest way of using a worm drive saw is to let it do half part of the work while you do the other half part. While purchasing a worm saw, there are certain fundamental features that you should carefully consider.
Qualities to Consider in Worm Saw Drives
- Blade Change Mechanism
A good worm saw drive is one whose blade can be easily changed. Nowadays, there are two kinds of worm drive saws, i.e., tool-assisted and tool-free. Changing the blade of a tool-free worm drive saw is quite simple.
This is because the change is manually done without the need for tools. On the other hand, the tool-assisted worm drive saw requires certain tools to change its’ blade, for example, a wrench and a screwdriver.
- Bevel Capacity
The bevel capacity is another fundamental feature that should be considered. A good worm drive saw is one whose bevel capacity enables you to cut a great angle. For example, a worm drive saw with a bevel capacity that exceeds 50 degrees is much recommended.
- Cutting Line Visibility
A good worm drive saw is one that has a clear sight of the cutting line. This will ensure that your cutting is accurate and will protect you from unnecessary injury.
- Maximum Cutting Depth
You should ensure that the cutting depth of your worm drive saw is well suited to handle the particular tasks effectively.
- Dust Blower
A dust blower is a significant feature because it blows away dust from the cutting line, thus keeping the working area clean. This helps in improving the cutting accuracy of the worm drive saw.
- Motor Housing and Robustness
A formidable worm drive saw is one that has a robust motor that is housed in a metal case. This will ensure durability and will also make the saw perform tasks effectively.
The worm drive saw is a machine that is used in work that requires framing and renovation. Hence, it is a vital tool that is used in the field of building and construction. These guidelines are essential because they reveal what is a worm drive saw, its’ features, and how it should be used.
