Solving Problems With Drill Press Tables
When it comes to woodworking, one tool that can pose challenges is the drill press. While a drill press is essential for precision drilling, it often has limited table space. This limitation becomes problematic when working with larger or unwieldy pieces of wood.
To solve this problem, woodworkers can use a tool called a jig. A jig is a device used in woodworking to guide tools, such as drills, in achieving precise cuts or holes. In the case of drill press tables, a custom jig can be created to fit securely onto the table. By using this custom jig, woodworkers can effectively expand the working area of the drill press table. This expanded area provides more flexibility when working on larger woodworking projects.
Making Drill Press Tables Larger For Woodworking
Expanding the working area of a drill press table is essential for woodworking projects that involve larger pieces of wood. With a larger surface area, woodworkers have more room to maneuver and position their workpieces properly. A jig can be effectively used to achieve this.
By attaching a custom-made jig to the existing drill press table, woodworkers can easily increase the working area. The jig is typically made from a sturdy material like medium-density fiberboard (MDF) to ensure stability. It is designed to fit securely onto the table and provides a larger surface area for woodworking tasks. This allows for the accommodation of larger workpieces, making it easier to achieve accurate and precise cuts.

Adding A Fence Or Insert To Drill Press Tables
Another common problem encountered when working with drill press tables is the lack of a fence or insert. A fence is a guide that helps in achieving accurate and straight cuts, while an insert allows for the drilling of holes with precision. These additions to a drill press table can greatly enhance its functionality, and a jig can assist in their installation.
By creating a custom-made jig, woodworkers can easily add a fence or insert to their drill press tables. The jig is designed to attach securely to the table, providing a stable base for the fence or insert. This ensures that they remain in place during the woodworking process. The jig can be made from medium-density fiberboard or other sturdy materials and is adjustable to accommodate different sizes of fences or inserts. With the help of a jig, woodworkers can achieve clean and accurate cuts or holes.

Creating A Jig From Medium-Density Fiberboard
Medium-density fiberboard (MDF) is a versatile and commonly used material in woodworking. It is an excellent choice for creating jigs due to its stability and ease of shaping.
When creating a custom jig, MDF can be an ideal material to work with.
To create a jig from MDF, woodworkers need to:
- Measure and cut the material to the desired shape and dimensions.
- Shape, drill, and sand the MDF to achieve the desired design using common woodworking tools.
Once the jig is constructed, it can be attached to the drill press table using clamps or screws.
MDF jigs are sturdy and provide a reliable base for various woodworking tasks.
Attaching A Jig To A Machine’s Table With Lag Screws
To ensure that a jig remains stable and secure during use, it is essential to attach it firmly to the machine’s table. One way to achieve this is by using lag screws.
Lag screws, also known as coach screws, are large screws with coarse threads and a hexagonal head. These screws are designed to provide a strong and durable connection. When attaching a jig to a machine’s table, lag screws can be used to ensure that the jig remains securely in place. The screws are inserted through pre-drilled holes in the jig and then tightened into the table using a wrench or a socket driver.
Using lag screws to attach a jig provides a reliable and sturdy connection, allowing woodworkers to work with confidence. It ensures that the jig remains in place, preventing any unwanted movement during the woodworking process.
