GOINGMAKE Thin Rip Jig Table Saw Jig Guide for Making Repetitive Narrow Thin Strip Cuts Woodworking Tools Fast Thin Ripping Guide for Table Saw Band Saw Router Table Fits for 3/8" x 3/4" T Slot
The GOINGMAKE Thin Rip Jig Table Saw Jig Guide is a tool designed for making repetitive narrow thin strip cuts on your table saw, band saw, or router table. It is built to fit 3/8″ x 3/4″ T slots, U shape slots, and 1/4″ x 3/8″ T slots, so it should work with most standard saws. The jig can extend up to 8 inches from the center of the miter slot to the blade, giving you a good range for different strip widths.
Using this jig is pretty straightforward.
You just slide the guide into your T-track miter slot and lock it in place in front of the saw blade. There is no complicated setup. The one way roller bearing is a key feature here. It lets the workpiece move forward but prevents kickback, which makes the cutting process both safe and fast.
You can keep making the same thickness strips over and over without worring about the material slipping back at you.
For precise cuts, the GOINGMAKE guide includes laser engraving scales in both millimeters and inches. The zero clearance design helps you set the right distance easily. To set it up, you first bring the bearing close to the saw blade and adjust the scale indicator to the nearest mark. Then you set the dimension for your strips.

You will find it adapts to most standard workshop setups easily.
One of the best features is the flexible roller assembly. It has three rollers with a premium ball bearing system. You can install it on the left or right side of your blade. You can also flip it 180 degrees to even out wear over time. This design helps the jig slide smoothly and reduces chip-out on your cuts.
It gives you clean, repeatable results every time you use it.
Setup is very simple because the jig comes pre-assembled. You don’t need any tools to install or adjust it. Just use the dual locking knobs and expansion screws to tighten it in place.

Table Saw Finger Joint Jig Buying Guide
A finger joint jig creates interlocking joints for strong, attractive box construction. If you have ever tried cutting finger joints freehand, you know how frustrating it is to get them perfectly aligned. This is where a dedicated jig for your table saw comes in. It takes teh guesswork out and gives you repeatable results every time. But not all jigs are the same. Some work better for small boxes, others for larger panels. This guide will help you pick the right one for your projects.
Material and Build Quality
A jig made from aluminum or steel will last longer than one made from plastic. Aluminum is light and resists rust, while steel is heavier but very stable. Look for a jig that doesn’t flex when you push it through the saw. A wobbly jig means uneven cuts. You want something that feels solid in your hands.
Finger Spacing Options
Different projects need different finger widths. A jig that lets you adjust the spacing gives you more flexibility. Some jigs come with fixed templates, others use a slider system. Ask yourself: do you make small jewelry boxes or larger cabinets? The answer will tell you what spacing range you need.
Ease of Setup and Adjustment
Nobody wants to spend an hour setting up a jig. Look for one with clear markings and simple adjustments. Some jigs use a single knob to lock everything in place. Others require multiple screws. The faster you can switch between settings, the more time you save on the job.
Maximum Board Width Capacity
Not all jigs can handle wide boards. If you plan to make larger projects, check the maximum width the jig accepts. A jig that only takes 6-inch boards will limit what you can build. Make sure it matches the size of your typical work pieces.
Compatibility with Your Table Saw
Most jigs fit standard table saw miter slots, but some have specific requirements. Measure your slot width before buying. A jig that doesn’t slide smoothly in your slot will cause frustration and poor cuts. Check if the jig uses a single or dual miter bar for better stability.
Pick a jig that fits your workshop and your projects. A good jig makes finger joints quick and accurate, letting you focus on the fun part—building something great.
Frequently Asked Questions About Table Saw Finger Joint Jig
What is a table saw finger joint jig?
It’s a tool that helps you cut interlocking fingers on wood. You attach it to your table saw. Then you can make strong joints for boxes, drawers, and frames. It’s safer and more accurate than freehand cutting.
Do I need a special table saw for this jig?
No, you don’t. Most finger joint jigs work with standard table saws. Just check teh fit for your saw’s miter slots. Some jigs are adjustable. Others are fixed size. Measure your slots before buying.
Can I use a finger joint jig with a dado blade?
Yes, many people do. A stacked dado blade cuts the fingers faster. But you can also use a regular blade with multiple passes. The jig keeps everything aligned either way. Just make sure your jig supports the blade width you choose.
How thick of wood can I joint with it?
It depends on the jig. Most handle wood up to 3/4 inch thick. Some heavy-duty models go up to 1 inch. Check the jig’s specs. Thicker wood needs longer fingers for strength. Your jig must match the wood thickness.
Is it hard to set up a finger joint jig?
Not really. Most come with clear instructions. You align the jig with your blade. Then you set the finger spacing. It might take a few test cuts to get perfect. After that, it’s easy to use. Practice on scrap wood first.
Will it work for different finger widths?
Some jigs are fixed. Others let you adjust finger width. Fixed jigs are simpler but less flexible. Adjustable jigs cost more. Think about what projects you will make. A fixed jig is fine for standard box joints. An adjustable one gives you more options.
Do I need a miter gauge with this jig?
Most jigs replace your miter gauge. They slide directly in the miter slot. Some use a separate miter gauge. Read the product description. The best jigs lock securely. This prevents movement during cuts. Safety is important.
How do I maintain a finger joint jig?
Keep it clean. Sawdust can cause misalignment. Wipe it after each use. Check screws for tightness. Lubricate sliding parts lightly. Store it in a dry place. A well-maintained jig lasts for years. Your joints will stay accurate.
Before You Decide
Getting clean joints with a table saw can feel tricky at first, but this jig takes the guesswork away. You just set your dado blade depth, clamp the jig in place, and run your workpiece through. The results are repeatable every time—no measuring or marking needed. It’s a simple tool that saves you from frustrating mistakes and wasted wood. If you build boxes, drawers, or small cabinets, this is a smart upgrade. The jig works with most standard table saws and fits easily in your shop.
You don’t need to be a pro to get professional-looking finger joints. The table saw finger joint jig is built to hold your material steady and line up each cut perfectly. So if your last project had gaps or uneven fingers, this tool can fix that. Its a small investment that makes a big difference in your woodworking results.
