This jig is compatible with most table saws featuring a 3/8-inch by 3/4-inch miter slot. Constructed from CNC precision-milled cast iron, it offers durability and accuracy for both right and left tilt saws. This manual provides essential information for the safe and effective use, setup, maintenance, and troubleshooting of your tenoning jig.
2. Safety Information
Always prioritize safety when operating power tools and accessories. Read and understand all instructions before use. Failure to follow safety guidelines can result in serious injury.
General Safety Precautions:
- Always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and dust mask.
- Ensure your work area is clean, well-lit, and free of obstructions.
- Keep hands and fingers clear of the saw blade at all times.
- Disconnect power to the table saw before making any adjustments or performing maintenance on the jig.
- Ensure the tenoning jig is securely seated in the miter slot and all clamps are tightened before operation.
- Do not operate the jig if any parts are damaged or missing.
- Keep children and bystanders away from the operating area.

Key Components:
- Main Body: The robust cast iron frame that supports all other components.
- Miter Bar: Slides into the table saw's miter slot, ensuring accurate movement. Features adjustable set screws for a snug fit.
- Adjustable Backstop: Pivots from 45 to 90 degrees with positive stops, allowing for angled tenons.
- Micro-Fine Adjustment Knob: Provides precise control over the width-of-cut settings, down to 4/1000-inch.
- Quick-Release Hold Down Clamp: Secures the workpiece firmly in place, accommodating stock up to 3-1/4 inches thick.
- Ergonomic Handles: Two handles positioned for comfortable and controlled operation during cuts.
4. Setup and Assembly
Proper assembly and setup are crucial for the accuracy and safe operation of your tenoning jig.
4.1. Cleaning and Preparation:
The jig's machined surfaces are coated with a preservative to prevent rust during shipping. This must be thoroughly removed before use.
- Disassemble any partially assembled components to access all coated surfaces.
- Using a rag moistened with kerosene or a suitable degreaser, carefully wipe down all surfaces until the preservative is completely removed. Ensure adequate ventilation during this process.
- Reassemble any components that were disassembled for cleaning.
4.2. Miter Bar Adjustment:
The miter bar must fit snugly in your table saw's miter slot to ensure accurate cuts.
- Inspect the miter bar for washers on the ends. If your table saw does not have a "T" slot, these washers should be removed. If your saw has a "T" slot but the jig does not fit, you may need to remove or shim the washers.
- Adjust the three set screws on the miter bar to achieve a snug fit in your table saw's miter slot without binding. These screws may have thread lock, requiring firm but careful adjustment.
4.3. Backstop Alignment:
The backstop must be precisely aligned perpendicular to the table saw blade for accurate tenons.
- Position the jig on your table saw.
- Adjust the backstop to the 90-degree position.
- Use a reliable square or a straight edge placed between the backstop and the saw blade to ensure perfect perpendicularity. It may be necessary to use a straight edge to reach the adjustment screws.
- Tighten the lock knob for the backstop. Be aware that tightening may cause slight movement, so re-verify alignment after tightening.
5. Operating Instructions
Follow these steps for safe and effective use of the DELTA 34-184 Tenoning Jig.
- Prepare Workpiece: Ensure your workpiece is properly dimensioned and free of defects. The jig can handle stock up to 3-1/4 inches thick.
- Set Blade Height: Adjust your table saw blade height according to the desired tenon thickness.
- Clamp Workpiece: Place the workpiece against the backstop and secure it firmly with the quick-release hold down clamp. The continuously adjustable clamp arm allows for easy clamping of various stock sizes.
- Adjust Cut Depth/Position:
- For macro adjustments, push the button to quickly move the jig.
- For fine adjustments, use the micro-fine adjustment knob. A full turn of this knob results in approximately 1/16-inch movement. Be mindful of potential backlash in this adjustment.
- Make the Cut: Holding the two ergonomic handles, smoothly push the jig and workpiece through the saw blade. Maintain consistent pressure and a steady feed rate.
- Repeat Cuts: For wider tenons or to refine the cut, adjust the micro-fine adjustment knob and repeat the cutting process as needed.
- Angled Tenons: To create angled tenons, adjust the backstop to the desired angle between 45 and 90 degrees using the positive stops.
6. Maintenance
Regular maintenance will ensure the longevity and continued accuracy of your DELTA 34-184 Tenoning Jig.
- Cleaning: After each use, wipe down the jig to remove sawdust and debris. For stubborn residue, use a mild cleaner.
- Lubrication: Periodically apply a light coat of machine oil to moving parts, such as the adjustment screw threads and the miter bar, to ensure smooth operation and prevent rust.
- Inspection: Regularly inspect all fasteners and components for tightness and wear. Tighten any loose screws and replace worn or damaged parts immediately.
- Storage: Store the jig in a clean, dry environment to prevent rust and corrosion.
7. Troubleshooting
This section addresses common issues you might encounter with your tenoning jig.
| Problem | Possible Cause | Solution |
|---|---|---|
| Jig does not slide smoothly in miter slot. | Miter bar set screws are too tight; miter bar is dirty; washers are interfering. | Loosen miter bar set screws slightly; clean miter bar and slot; remove or shim washers if necessary. |
| Tenons are not square or parallel. | Backstop not aligned perpendicular to blade; jig not parallel to blade; manufacturing defect. | Re-align backstop carefully (Section 4.3); ensure miter bar is properly adjusted; if issues persist, contact customer support. |
| Adjustment knob has excessive backlash. | Normal wear or manufacturing tolerance. | Account for backlash by overshooting and then backing into the desired setting. |
| Screws stripping or difficult to adjust. | Thread lock present; poor quality screws; incorrect tool used. | Apply more force carefully or use a higher quality hex key; if stripped, replace screws. |
