Drill a Pilot Hole

Drill A Pilot Hole

  • Drilling a pilot hole is the first step in ensuring accuracy and efficiency when drilling bench dog holes.
  • A pilot hole is a small hole drilled into the wood prior to drilling the bench dog hole. It helps to guide the drill bit and prevent it from slipping.
  • Use a drill bit that is slightly smaller than the size of the bench dog hole that you plan to drill. This will ensure that the drill bit does not slip when drilling the pilot hole.
  • Once the pilot hole is drilled, use a counterbore to clean up the edges of the pilot hole.
  • A counterbore is a drill bit with a pilot drill attached to it. It is used to clean up the edges of the pilot hole and remove any splinters.
  • Once the pilot hole is drilled and counterbored, use a drill bit that is the same size as the bench dog hole and drill the hole.

  • Drill bit: Choose a drill bit that is the same size as the bench dog hole you want to drill. Using a larger bit will result in a hole that is too loose, while using a smaller bit will make the hole too tight.
  • Speed: Select the correct speed for the drill bit size. Too high a speed can cause the drill bit to overheat and burn the wood, while too low a speed will cause the bit to bind and chip the wood.
  • Pressure: Apply firm, even pressure when drilling. Too much pressure will cause the bit to get stuck, while too little pressure can cause it to slip and damage the material.
  • Feed rate: Feed the bit into the material at a slow and steady rate. Going too quickly can cause the bit to overheat, while going too slowly can result in a hole that is too large or small.
  • Depth: Measure the depth of the hole with a ruler or caliper before drilling. This will ensure that the hole is the right size and will help to avoid any potential issues with the bench dog hole.

Drill Additional Holes

Drill Additional Holes

To maximize efficiency and accuracy, it is recommended that you drill additional holes in the bench top. This will allow you to align the bench dog holes correctly and evenly spaced from one another. To do this, first mark the desired location of the additional holes with a pencil. Then, depending on the size of the hole you are drilling, select an appropriate drill bit, preferably one with a spade-tip that is slightly larger than the size of the bench dog hole. Using a drill press, slowly drill the additional holes at the marked locations. Ensure that the drill bit is not going too deep, as this could damage your drill press and bench top. When finished, the additional holes should be perfectly aligned with the original bench dog holes.

Countersink the Dog Hole

Countersink The Dog Hole

Once the benchdog hole has been drilled, use a countersinking bit to create a tapered hole that will allow the benchdog to fit snugly and flush against the work surface. Set the depth of the countersink bit to match the thickness of the benchdog head. Start the drill slowly and adjust the speed as needed. Be sure to keep the drill bit perpendicular to the surface of the workpiece and check the depth of the countersink regularly to prevent over-drilling. When finished, the benchdog should fit flush against the surface.

Note: Countersinking the dog hole is an important step to ensure the benchdog functions properly and is safe to use.

Create the Bench Dog

Create The Bench Dog

Step Instructions
1 Cut a piece of wood to the desired size for the bench dog.
2 Drill a pilot hole in the center of the wood. The size of the pilot hole should match the size of the drill bit that will be used for the bench dog hole.
3 Using the drill bit, drill a hole in the center of the wood. The size of the hole should be slightly larger than the size of the drill bit.
4 Using a countersink bit, cut a hole in the bottom of the wood. This hole should be slightly larger than the size of the drill bit.
5 Using a chisel, cut a groove in the sides of the wood. This groove should be slightly larger than the size of the drill bit.
6 Apply a coat of finish to the bench dog.

Once the bench dog is created, it is ready to be used for drilling bench dog holes.

Test the Fit

After drilling the holes, check to ensure that the bench dogs fit properly. This can be done by inserting the dogs into the holes and see if they fit securely. If the fit is too tight, use a bit of sandpaper to file down the edges of the hole. If the fit is too loose, consider adding a piece of wood or adhesive to the hole to make it snugger. To ensure that the bench dogs won’t move around too much, use a carpenter’s glue to secure them in place.

Once the bench dogs fit properly, check to make sure the holes are aligned with one another. This can be done by measuring the distance between each hole and making sure they are equal. If the holes are not aligned, then you may need to adjust the position of the drill bit before re-drilling them.

Finally, test the fit of the bench dogs in the workbench. This can be done by placing a few pieces of scrap wood over the holes and then inserting the dogs into the holes. If the dogs fit securely and the holes are aligned correctly, then you are all set to use your bench dog holes.

Frequently Asked Questions

What type of drill bit should I use when drilling bench dog holes?

  • Forstner Bit – Forstner bits are great for creating precise, flat-bottomed holes. The flat bottom gives a stable base for the bench dog to sit on, allowing it to remain secure while in use.
  • Twist Bit – Twist bits are standard drill bits used for drilling into wood. They are great for drilling bench dog holes because they can easily bore through the wood quickly and accurately.
  • Auger Bit – Auger bits are the best choice for drilling bench dog holes in thick or hard woods. They are longer and thicker than twist bits and they have a screw tip that helps it to quickly and easily cut through the wood.

How do I determine the size of the bench dog holes?

The size of the bench dog holes should be determined based on the size of the material you are drilling. Generally, it is recommended to use a bit that is 1/8-inch larger than the diameter of the material. For example, if you are drilling 1/4-inch material, you should use a 5/16-inch bit. Additionally, it is important to consider the size of the bench dog hole in relation to the size of the bench dog itself. The bench dog hole should be slightly larger than the bench dog to ensure a snug fit.

What is the Best Way to Ensure Accuracy When Drilling Bench Dog Holes?

The key to ensuring accuracy when drilling bench dog holes is to use a drill press. With a drill press, you can adjust the depth and angle of the hole, as well as the speed of the drill bit, which ensures that each hole is properly drilled. Additionally, it is important to use a drill bit specifically designed for the material you are drilling. Using the wrong drill bit can cause the hole to be too large or too small. It is also important to use clamps or a drill press vise to hold the workpiece securely in place while drilling. Finally, using a center punch to mark the center of the hole before drilling is a great way to ensure accuracy and precision.

What safety precautions should I take when drilling bench dog holes?

  • Wear safety goggles: Always wear safety goggles when drilling bench dog holes in order to protect your eyes from any wood chips or wood dust.
