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 made for making repetitive narrow thin strip cuts on your table saw, band saw, or router table. This tool is all about getting consistent results without the fuss.
It is really easy to use. You just slide the guide into the T-track miter slot of your saw and lock it in place in front of the blade. It fits 3/8″ x 3/4″ T slots, U shape slots, and 1/4″ x 3/8″ T slots.
The jig can extend up to 8 inches from the center of the miter slot to the blade. This means you can cut thin strips consistently with very little effort. It takes the guesswork out of the process.
Safety is a big deal with this jig. The one way roller bearing makes sure the workpiece only moves forwards. This prevents kickback, which is a common hazzard when ripping thin strips. You can make fast, repetitive cuts without worrying about the wood shooting back at you.
Each strip stays the same thickness because the guide keeps everything lined up.
For precise work, the GOINGMAKE jig has laser engraved scales in both mm and inches. The zero clearance design helps you set the right distance quickly. To set it up, you bring the bearing close to the saw blade and adjust the scale indicator to the nearest mark. Then you set the dimention you want for your strips. Every cut after that will be the same size as the first one.

When not in use, they store neatly in slots on the sled, so you won’t loose them.
The sliding sled is smooth and has long “skis” that help it stay square to the router bit. There are also tabs on the bottom that stop the sled at the end of your cut. This gives you consistent results without guessing. You lock the sled into the miter slot of your router table using comfortable, easy-to-grip knobs.
Once it’s locked in, your ready to start routing.
The platform is made from MDF and has a low-friction melamine coating. This coating helps the sled slide easy and also protects the surface.

Table Saw Box Joint Jig Buying Guide
Cutting precise box joints requires a stable jig aligned to your blade. Without one, you’re left with loose, sloppy joints that ruin your project. A table saw box joint jig turns that frustration into tight, professional results. But not all jigs are teh same. The wrong choice can waste your time and material. Here’s what to look for.
Finger Spacing Options
Different projects need different joint sizes. Some jigs come with fixed spacing, which limits you to one finger width. That’s fine if you only build small boxes. But if you want to switch from thick drawer joints to delicate jewelry boxes, you need adjustable spacing. Look for a jig with removable keys or a sliding mechanism. It gives you flexability without buying a second tool. Ask yourself: will you use it for one project or many?
Material and Build Quality
A flimsy jig shifts under pressure. That means crooked cuts. You want something sturdy, like aluminum or thick acrylic. These materials resist warping and hold alignment over time. Cheap plastic models might save you money upfront, but thay often flex during use. Ever had a joint that was tight on one side and loose on the other? That’s a jig problem. Spend a little more on a solid build—it pays off in accuracy.
Table Compatibility and Mounting
Not every jig fits every saw table. Check the miter slot width on your saw first. Some jigs use T-track systems, others rely on standard slots. If the jig doesn’t slide smoothly, you’ll fight it all day. Also, look at how it mounts. A jig that clamps down is easier to ajust than one that bolts in place. You want quick setup changes, not a wrenching session every time.
Frequently Asked Questions About Table Saw Box Joint Jig
What exactly is a box joint jig?
A box joint jig is a tool that attaches to your table saw. It helps you cut evenly spaced notches in wood. You use it to make strong, interlocking joints for boxes, drawers, and other projects.
Can I use any table saw with a box joint jig?
Most jigs work with standard 10-inch table saws. But you need to check the miter slot size first. Some saws have T-slots or odd-shaped slots. Make sure the jig fits your saw’s slot. Some jigs also clamp to the fence instead.
How do I choose the right jig for my project?
Think about what size joints you want. Some jigs let you cut different widths. Others are fixed. If you make big boxes, get a jig with a larger capacity. For small crafts, a simpler jig works fine. Also consider how easy it is to adjust.
Is a metal jig better than a wooden one?
Metal jigs are more durable and precise. They don’t warp over time. Wooden jigs are cheaper and you can make your own. But thay may need adjustment after humidity changes. For regular use, a metal jig is a solid choice.
Do I need a dado blade to use a box joint jig?
Yes, most jigs require a dado blade set. A standard blade only cuts one slot at a time. A dado blade cuts wider notches faster. Some jigs work with a single blade, but it’s slower. Check the jig’s instructions before buying.
How do I set up the jig for perfect joints?
Start by clamping the jig to your miter gauge or fence. Then adjust the fingers to match your blade width. Cut a test piece first. Check the fit. If it’s too tight, move the fence slightly. Keep testing until the joints snap together snugly.
Can a beginner use a box joint jig?
Yes, absolutly. It takes some practice but it’s not hard. Start with simple projects like small boxes. Watch a few videos to understand the setup. Once you get the hang of it, you’ll make strong joints quickly. Take your tme and be safe.
