Bench dogs are cylindrical or square pegs inserted into the workbench's surface to provide a clamping point. They come in handy for securing your workpieces at various levels, making your workbench versatile. Before diving into the tricks, let's ensure you know the essentials of bench dogs:

• What They Do: Bench dogs help to clamp your workpiece at different heights, providing an extra hand for you to work with.
• Types: There are different types including cylindrical, square, and expandable bench dogs.

Choosing the Right Drill Bit

<p class="pro-note">🔧 Note: The size of your bench dog hole should match the diameter of your bench dog. A common size is 3/4 inch or 19mm, but always measure yours to be sure!</p>

To begin, you need to select the right drill bit:

• Forstner Bits: They're ideal for a clean hole with flat bottoms, perfect for bench dogs.
• Spade Bits: A cheaper alternative, but you'll need to ensure they are sharp for clean edges.

Drilling holes sounds simple, but here are the tricks to make them perfect:

Trick 1: Use a Drill Guide for Perfectly Vertical Holes

• Why: A perfectly vertical hole ensures that your bench dog will fit snugly and work effectively.
• How: You can buy or make a drill guide from hardwood or plywood. Clamp it onto your workbench, align your drill bit in its center, and drill.

Trick 2: Create a Template for Consistent Spacing

• Why: Uniform spacing between holes allows for organized workpiece support and a cleaner look.
• How: Use a template made from thin plywood or hardboard. Mark the positions of the holes on the template and then use it as a guide to drill.

Trick 3: Avoid Tear-out with Backer Wood

• Why: Tear-out can damage your workbench's surface, leading to holes that are not as clean as they should be.
• How: Place a piece of scrap wood or backer wood underneath your benchtop before drilling. This will prevent the wood from splintering.

Trick 4: Drill in Stages

• Why: Drilling large holes at once can cause splintering or wandering of the bit.
• How: Drill small pilot holes first, then increase the size progressively to avoid sudden kickback or wandering.

Trick 5: Use a Countersink for a Professional Finish

• Why: A chamfered edge not only looks better but also prevents snagging and chipping.
• How: Use a countersink bit to slightly bevel the edges of the holes after drilling. This creates a smooth transition for the bench dog.

Testing and Adjusting Your Holes

After drilling, it's crucial to test your bench dog holes:

• Fit: Ensure the bench dogs fit snugly but not too tight. A bit of wiggle room is ideal for adjustments.
• Alignment: Make sure the holes are aligned in a straight line or grid for efficiency.

Final Touches for Aesthetic Appeal

• Sanding: Lightly sand the edges of your holes for a smoother fit and appearance.
• Finishing: Consider applying a finish to the inside of the holes to reduce friction.
