The Comprehensive Guide to Woodworking Bench Dogs

Bench dogs are essential woodworking tools used to secure workpieces on a workbench or multifunction table. They provide a stable and versatile clamping system, allowing for various woodworking tasks. While seemingly simple, bench dogs come in various designs, each with unique features and applications. Understanding these differences is key to choosing the right bench dog for your specific needs and woodworking style. Companies like Precision Dogs (precisiondogs.us) and Rutlands (www.rutlands.com) offer a wide selection of these tools.

Understanding Bench Dog Anatomy and Function

A typical bench dog consists of three main parts: the shaft, the collar, and the body. The shaft is the topmost part, protruding above the workbench surface. The collar sits below the shaft, preventing the dog from falling through the hole. The body is the portion that fits into the pre-drilled holes in the workbench. The body often features a tapped hole for a clamping knob, securing the dog firmly in place. This basic design is common across most brands, though variations exist.

Types of Bench Dogs and Their Applications

Different types of bench dogs cater to various woodworking needs. The following table summarizes the common types and their applications:

Type	Description	Application	Advantages	Disadvantages
Standard Collared	Classic design with a prominent collar.	General workholding, fixturing.	Easy to use, widely available.	Can obstruct the work surface.
Close Fit	Precisely machined for minimal play in the hole.	Accurate positioning, repeatable setups.	High accuracy.	Can be difficult to use in workbenches with variations in hole size.
Chamfered	Designed to rest on a chamfered lip in the hole.	Precise positioning, self-centering.	Superior accuracy and self-centering.	Requires chamfered holes.
Guide Rail Dogs	Connect track saw guide rails to the workbench.	Using track saws on workbenches with bench dog holes.	Secure guide rail attachment.	Specialized design, limited applications.
Bench Connecting Dogs	Designed for connecting multiple work surfaces.	Expanding or modular workbenches.	Strong clamping, precise registration.	Specialized design, limited applications.
Standalone Clamps	Integrate clamping mechanisms directly into the bench dog design.	Standalone clamping without additional clamps.	Convenient, strong.	Requires specific design bench dogs.
Standoff/Protection	Keep workpieces elevated from the workbench surface.	Glue-up, finishing.	Prevents workpiece from getting damaged, makes cleanup easier.	Limited clamping capabilities.

FAQs

1. What is the difference between a standard fit and a close fit bench dog?

A standard fit bench dog has a slightly smaller diameter than the hole, allowing for some movement. A close fit dog is precisely machined to minimize this play, improving accuracy.

2. How do I choose the right bench dog height?

Bench dog height should be chosen based on the thickness of your workpiece and the height of your clamping tools. Taller dogs accommodate thicker pieces.

3. Can I use bench dogs on any workbench?

No, you need a workbench with pre-drilled holes of the appropriate size (usually 20mm) to use bench dogs effectively.

4. What are chamfered bench dogs, and why are they useful?

Chamfered bench dogs have a beveled edge that rests on a chamfered hole, self-centering the dog for greater accuracy.

5. Are bench dogs necessary for woodworking?

While not strictly necessary, bench dogs are highly beneficial for efficient and secure workholding, especially for larger or more complex projects.
