Introduction
The Milescraft 1218 Dovetail Master Template is designed to assist in creating precise dovetail and box joints for various woodworking projects. This system allows users to craft custom jigs from scrap materials, reducing the need for expensive replacements. The polycarbonate panel features pre-cut guide openings for consistent results, enabling both pin and tail openings for full, spaced, and angled dovetails of varying sizes.

Setup
- Secure Mounting: Securely mount the Dovetail Template to a stable workbench or work surface. Ensure the template is clamped firmly to prevent any movement during routing operations.
- Bit Selection: Select the appropriate router bit for your desired joint. Use the 8° dovetail bit for dovetail joints and one of the straight bits for box joints.
- Router Bit Installation: Install the chosen bit into your router's collet. Ensure the bit is properly tightened and set to the correct depth. Refer to your router's manual for specific bit installation and depth adjustment procedures.
- Test Cuts: Always perform test cuts on scrap material of the same thickness and species as your project pieces. This allows you to verify the bit depth and template alignment before working on your final project. Adjustments may be necessary to achieve a perfect fit.
Operating Instructions
Follow these steps to create precise dovetail and box joints using your Milescraft 1218 Dovetail Master Template:
- Prepare Workpieces: Ensure your wood pieces are cut to the correct dimensions and are perfectly square. Clearly mark the pin and tail boards to avoid confusion during routing.
- Routing Tails: Position the workpiece designated for the tails against the template. Secure it firmly with clamps, ensuring it does not shift. Using the 8° dovetail bit, guide your router along the template's openings to cut the tails. Maintain a consistent feed rate and pressure.
- Routing Pins: Position the workpiece designated for the pins against the template. Secure it firmly. Using the appropriate straight bit (or the specific bit for pins if different), guide your router along the template's openings to cut the pins.
- Creating Box Joints: For box joints, use one of the provided straight bits. Follow a similar process as for dovetails, ensuring precise alignment of the template and workpiece for clean, interlocking joints.
- Assembly and Finishing: After routing, carefully test fit the joint. If the fit is too loose or too tight, make small adjustments to your router's bit depth and re-cut on scrap material until the desired fit is achieved. Once satisfied, apply wood glue to the joint surfaces and clamp the pieces together until the glue is fully cured.

Instructional Video
Video 1: This video demonstrates the general operation of a dovetail jig master system, similar to the Milescraft 1218. It illustrates how to use a router with a template to create dovetail and box joints. Note that the specific jig shown may vary from the Milescraft 1218, but the principles of operation are applicable.
Maintenance
Proper maintenance ensures the longevity and performance of your Dovetail Master Template:
- Cleaning the Template: After each use, clean the polycarbonate template with a soft, damp cloth to remove sawdust, wood chips, and any adhesive residue. Avoid using harsh chemicals or abrasive cleaners that could scratch or damage the template surface.
- Router Bit Care: Keep your router bits sharp and free of resin buildup. Use a specialized router bit cleaner to remove pitch and sap. Dull or dirty bits can cause poor cuts and excessive tear-out. Store bits in a protective case to prevent damage to the cutting edges.
- Storage: Store the Dovetail Master Template in a dry, clean environment away from direct sunlight, extreme temperatures, or high humidity. This helps prevent warping or degradation of the polycarbonate material.
Troubleshooting
Here are solutions to common issues you might encounter:
- Excessive Tear-out: If you experience significant tear-out, especially on the entry or exit points of the cut, ensure your router bits are sharp. Try using a thin sacrificial board clamped in front of the workpiece to provide support for the wood fibers. Adjust your router's feed rate to be slower and more controlled.
- Loose or Tight Joints: The fit of your joints is primarily controlled by the router bit's depth setting. A slightly deeper cut will result in a looser joint, while a shallower cut will create a tighter fit. Make small, incremental adjustments to the router bit depth and test on scrap material until the desired snug fit is achieved. Also, ensure the template is securely clamped and not shifting during routing.
- Inconsistent Cuts: Verify that the router base is held flat against the template and that the router is kept perpendicular to the workpiece throughout the entire cut. Check for any play or looseness in the router's collet or the installed bit, which could lead to uneven cuts.
