Overview of Craftsman Router Parts
The typical Craftsman router consists of several key parts, each designed to perform specific tasks. These include the motor assembly, collet and bit, base, plunge mechanism (if applicable), and various accessories. Understanding these parts will help you identify problems and perform repairs or upgrades effectively.
Main Components of a Craftsman Router
Motor Assembly
The motor assembly is the heart of the router, providing the rotational power needed to cut and shape materials. Craftsman routers typically feature either fixed-base or plunge-base designs, both powered by an electric motor.
- Motor Housing: Encases the motor and provides structural support.
- Motor Brushes: Maintain electrical contact with the motor's armature; they wear out over time and need replacement.
- Vents: Allow cooling airflow to prevent overheating.
- Power Switch: Turns the router on and off, often with variable speed control.
Collet and Collet Chuck
The collet is a critical component that holds the router bit securely in place.
- Collet: A tapered sleeve that grips the shank of the router bit.
- Collet Chuck: The part of the router that houses the collet and attaches to the motor spindle.
- Collet Sizes: Common sizes include ¼ inch and ½ inch, accommodating different bit shank diameters.
Properly maintaining and replacing collets is vital for safe operation and clean cuts.
Router Bits
Though technically not a part of the router itself, bits are interchangeable accessories that significantly affect performance.
- Types of Bits: Straight bits, chamfer bits, round-over bits, flush trim bits, etc.
- Installation: Inserted into the collet and tightened securely.
Base Plate
The base plate forms the foundation of the router, guiding its movement.
- Fixed Base: Provides stable, fixed depth routing.
- Plunge Base: Allows the bit to be plunged into the material at adjustable depths.
- Material: Usually made of aluminum or plastic for durability and lightweight handling.
Plunge Mechanism (for Plunge Routers)
The plunge mechanism enables vertical movement, essential for tasks like mortising.
- Spring-loaded Arm: Allows the router to be plunged into the workpiece smoothly.
- Depth Adjustment Knob: Sets the depth of cut.
Depth Adjustment System
Precise depth control is crucial for accurate routing.
- Knobs or Cranks: Used to set and lock the depth.
- Scales or Digital Readouts: Help in setting exact depths.
Power Cord and Switches
These electrical components are vital for safe and reliable operation.
- Power Cord: Supplies electricity to the motor.
- On/Off Switch: Controls power, often with safety features like lock-on buttons.
- Variable Speed Control: Adjusts the motor's RPM for different materials and bits.
Additional Parts and Accessories
- Edge Guides: Assist in routing along edges with precision.
- Template Guides: Help follow patterns or templates.
- Dust Extraction Attachments: Minimize debris and improve visibility.
- Router Lift: Facilitates height adjustments for fine control.
