3. Initial Setup and Router Attachment

1. Router Compatibility: The CRB7 is designed to fit a wide range of routers. Ensure your router's baseplate allows for secure attachment of the CRB7's rods.
2. Attaching the CRB7 Base:
   • Loosen the rod adjustment mechanism on the CRB7.
   • Align the CRB7's rods with the mounting holes or slots on your router's baseplate.
   • Slide the CRB7 onto the router, ensuring a snug fit. The offset design allows for flexibility.
   • Tighten the rod adjustment mechanism to secure the CRB7 firmly to your router.
3. Bit Installation: Install the appropriate router bit for your intended operation into your router's collet, following your router's manufacturer instructions.
4. Micro Adjustment: Utilize the micro adjuster on the CRB7 to precisely position the router bit relative to the jig's guides or the workpiece. This allows for fine-tuning without disturbing the main setup.

4. Operating Instructions for Key Functions

The CRB7 system offers multiple functions. Always ensure the router is unplugged before making adjustments or changing bits.

4.1 Small Circle Cutting Jig

This function allows for routing precision circles and holes smaller than the router's base. The micro-adjuster facilitates precise diameter setting.

• Minimum Diameter: 1.5 inches (38mm)
• Maximum Diameter: 17.5 inches (445mm)

1. Attach the small circle cutting accessory to the CRB7.
2. Set the desired circle diameter using the micro-adjuster.
3. Secure the workpiece and position the jig.
4. Engage the router and carefully guide it to cut the circle.

4.2 Large Circle Cutting Jig

Enables cutting circles over 4 feet (1.2 meters) in diameter with high precision. The design allows for quick setup without removing the router from the CRB7.

1. Attach the large circle cutting accessory.
2. Establish the center point and radius for the large circle.
3. Secure the pivot point and the workpiece.
4. Guide the router smoothly around the pivot to achieve the cut.

4.3 Router Guide Side Fence

Functions as a parallel edge guide for routing dados or grooves parallel to an edge. It offers a greater range and easier setup compared to standard edge guides.

1. Attach the side fence accessory to the CRB7.
2. Adjust the fence distance from the router bit to match the desired dado or groove dimension.
3. Secure the workpiece.
4. Guide the CRB7 along the edge of the workpiece, keeping the fence flush.

4.4 Mortise Hinge Lock and Flute Jig

This accessory provides a stable platform for precise mortising, hinge rebates, lock rebates, and repetitive flute cutting.

1. Attach the Mortise Hinge Lock and Flute Jig to the CRB7.
2. Position the micro-adjustable jaws to securely hold the workpiece.
3. Set the depth and position of the cut using the CRB7's micro-adjuster.
4. Perform the mortise, rebate, or flute cut, utilizing the clear sight lines for accuracy.

4.5 Additional Functions

The CRB7 system also supports the following operations:

• Offset Router Base Plate: Provides an extended and stable platform for routing.
• Anti-Tilt Router Support: Helps maintain router stability during edge routing operations.
• Adjustable Mortising: Allows for precise and repeatable mortise cuts.
• False Panel Rebate Copier: For replicating rebates on panels.
• Adjustable Straight Edge Clamp Guide: Used with a straight edge for accurate linear routing.
• Edge and Dowel Trim Kit: For flush trimming hardwood edgings, lippings, and dowel heads. This kit utilizes a Tracer Racer Bearing for consistent cutter height and smooth passes.
