Trend Varijig Tenon and Grooving Jig (VJS/TG/JIG) for precise tenons and grooves
Product description
What it’s for and the job it makes easier
If you’re cutting tenons and grooves for joinery, the hard part isn’t just routing—it’s doing it consistently, board after board. The Trend Varijig Tenon and Grooving Jig (VJS/TG/JIG) is built around that exact idea: guiding your router so grooves and tenons land where they should.
On paper, it’s aimed at repeatable, accurate work rather than one-off “good enough” cuts. It’s the kind of jig that can make template-style work feel more controlled, especially if you’re building a run of joints for projects like frames or practical furniture. Depending on your workflow, it may also help when you’re trying to keep groove and tenon positions aligned without constantly re-measuring.
The essentials: what stands out
This jig’s layout focuses on control. It includes sliding stops, a square fence/back plate, and an adjustable frame. That combination is useful because joinery accuracy often comes down to how stable your setup feels and how repeatable your measurements are.
A practical way to picture it: you set the jig up on the workpiece, attach your router with the correct guide bush, then run the cut through the jig’s path. With the stops and the adjustable frame, you’re less reliant on “freehand technique” for positioning, which is where many mistakes happen.
It also comes with the Varijig itself and fixing screws, so you’re not left hunting for basic fasteners to get started.
Key points to check before you buy
The big limitation is compatibility and workable size.
- Router guide bush projection requirement: you need to use the jig with a router that has a guide bush installed with a minimum projection of 5/16 inches.
- Maximum work length: the maximum working length is 15 3/4 inches.
That means it’s worth checking the size of your typical boards and the router setup you already own. If your projects routinely go beyond that working length, you may find it constrains you more than you’d like.
What you’ll notice in day-to-day use
This jig is designed for grooves and tenons, so you can expect it to behave like a joinery aid: setup first, then repeat.
The sliding stops and adjustable frame are the parts you’ll likely adjust the most. Once you’ve dialled in the position, the payoff is steadier results—less “how close did I land it this time?” and more “I can run the same cut again.”
That said, it’s not a magic shortcut. Like most routing jigs, you still need to take your time with initial setup and ensure your router and guide bush are installed correctly. If you’re after something fully automatic or that requires minimal setup every time, this may feel a bit more hands-on than expected.
Technical details (the bits that matter)
Technical details
- Type: Tenon and grooving jig for precise routing of grooves and tenons
- Maximum working length: 15 3/4 inches
- Router compatibility requirement: router with a guide bush installed with a minimum projection of 5/16 inches
- Included in the box: Varijig and fixing screws
Pros and cons, in plain terms
What it’s good at: - Bringing consistency to groove and tenon routing through a guided setup. - Providing adjustable and stabilising elements (sliding stops, square fence, adjustable frame) that support repeatable positioning.
Where it may fall short: - If your router doesn’t meet the guide bush projection requirement, it won’t sit right for the intended use. - If your typical workpieces exceed the listed maximum working length, you may need a different approach.
Who it suits (and who should look elsewhere)
It makes sense if you regularly cut grooves and tenons—particularly if you want more repeatability than you get with measurement-only layouts.
It may not suit you if: - Your router setup can’t meet the minimum guide bush projection requirement. - Your projects often need routing beyond 15 3/4 inches of working length.
Also worth noting: this is a joinery-specific jig. If you’re looking for general-purpose routing help for loads of different tasks, you might prefer a more universal setup.

Buying verdict
Is it worth it?
The Trend Varijig Tenon and Grooving Jig looks like a sensible purchase if you’re building joinery and want guided routing for grooves and tenons, with sliding stops and an adjustable frame to support consistent positioning.
You should consider it more carefully if your router’s guide bush projection doesn’t match the stated minimum, or if your typical timber sizes push past the maximum working length. In those cases, it can turn from “precision helper” into an annoying bottleneck.
If you’re set up to use it properly, it should earn its keep by making repeat cuts feel more predictable—just remember that good results still start with a careful initial setup.
Mini FAQ
Mini FAQ
Can I use it with any router? Not exactly. It needs a router with a guide bush installed, with a minimum projection of 5/16 inches.
What jobs is it designed for? Grooves and tenons, including applications like tables and cutting boards where this style of joinery is relevant.
Will it handle larger boards? There’s a maximum working length of 15 3/4 inches, so larger workpieces may be out of range.
What’s included for installation? The pack includes the Varijig and fixing screws.
