Introduction
If you’ve ever worked with rough lumber, you know how frustrating it can be to get perfectly straight edges without a dedicated jointer. But what if you could turn your table saw into a jointer with a simple, shop-made jig?
A jointer jig for table saw is a game-changer for woodworkers who want clean, square edges without investing in expensive machinery. In this guide, I’ll walk you through why you need one, how to build it, and the best techniques for flawless results—just like a pro.
Why Use a Jointer Jig on a Table Saw?
Jointers are great, but not everyone has the space or budget for one. A table saw jointer jig offers a smart alternative with several advantages:
✔ Cost-effective – No need for a separate jointer.
✔ Space-saving – Ideal for small workshops.
✔ Versatile – Works with any table saw.
✔ Precise – Delivers straight, glue-ready edges.
How a Jointer Jig Works
A jointer jig is essentially a straight-line ripping jig that holds your board at a slight angle while the table saw trims the edge. Here’s the basic principle:
- The board rides against a fence on the jig.
- The jig ensures only the high spots are cut.
- Multiple passes create a perfectly straight edge.
Building Your Own Jointer Jig for Table Saw
Materials You’ll Need
- ½” or ¾” plywood (for the base)
- Hardwood or MDF (for the fence)
- Screws or bolts
- T-track or clamps (optional)
Step-by-Step Instructions
1. Cut the Base
- Make a rectangular base slightly wider than your table saw’s rip capacity.
- Ensure it slides smoothly along the saw’s fence.
2. Attach the Fence
- Secure a straight hardwood or MDF fence at a 1–2° angle from the blade.
- This slight angle ensures only the high spots are trimmed.
3. Add Support & Clamping
- Install toggle clamps or T-tracks to hold the workpiece securely.
- Test for stability before use.
4. Fine-Tune the Jig
- Make test cuts on scrap wood.
- Adjust the fence angle if needed for smoother results.
Best Practices for Using a Table Saw Jointer Jig
To get the best results, follow these tips:
✅ Use a sharp blade – A rip blade or jointing blade works best.
✅ Take shallow cuts – Remove 1/16″–1/8″ per pass.
✅ Check for squareness – Ensure the jig doesn’t introduce twist.
✅ Work against the fence – Keep consistent pressure for even cuts.

Verdict: If you already own a table saw, a jointer jig is a no-brainer for occasional edge jointing.
Common Mistakes & How to Avoid Them
❌ Rushing the setup → Take time to align the fence correctly.
❌ Cutting too deep → Light passes prevent tear-out.
❌ Ignoring blade sharpness → Dull blades cause rough edges.
FAQ: Jointer Jig for Table Saw
1. Can a table saw jointer jig replace a real jointer?
For edge jointing, yes—it works great for most tasks. However, face jointing (flattening wide boards) still requires a planer or dedicated jointer.
2. What’s the best angle for the jig’s fence?
A 1–2° angle is ideal. Too steep, and you’ll remove too much material; too shallow, and it won’t joint effectively.
3. Do I need a special blade for jointing on a table saw?
A rip blade (24–30 teeth) works best, but a dedicated jointing blade (flat-top grind) improves results.
4. How do I prevent snipe (uneven cuts) with a jointer jig?
Ensure the jig is stable, use consistent feed pressure, and take lighter passes.
