This woodworking tip video was created by Jodee from Inspire Woodcraft. It compares wooden T-slots and aluminum T-track, offering practical advice on when one outperforms the other.
Instead of declaring a clear winner, Jodee explains why each material has its place in the workshop. The goal isn’t to pick a side—it’s to help woodworkers make better decisions based on cost, strength, ease of use, and the specific needs of their project.

Basic Differences Between the Two
Aluminum T-track is commonly used in jigs, fences, and other shop fixtures where strength and repeatable adjustments are important. It’s sleek, durable, and widely available in hardware stores and online.
Wooden T-slots, on the other hand, can be made from common hardwood or plywood using basic tools and inexpensive router bits. They serve a similar function, but with more flexibility and lower cost—especially for longer runs or one-off builds.
Comparing Costs
One of the biggest benefits of using wooden T-slots is the cost savings. For about $45, you can purchase two router bits and use them to make hundreds or even thousands of feet of track.
In contrast, aluminum T-track averages about $18 per four-foot stick. While not unreasonable on its own, using it in multiple jigs or across an entire bench can add up quickly. For woodworkers on a budget, the savings from going with wooden T-slots can be substantial over time.
Installation and Setup
Installing aluminum T-track involves routing a groove and securing the track with screws. But it’s not always plug-and-play—Jodee points out that you may need to drill your own holes and even countersink them. Sometimes, the provided screws are too long, requiring a trip to the hardware store for better-fitting ones.
By contrast, wooden tracks don’t need hardware at all. You route the groove and the slot, and you’re done. No glue, no screws, and no worrying about hole placement. This makes them especially appealing for woodworkers who prefer fast, flexible setups.
Flexibility and Customization
One area where wooden T-slots shine is in customization. You’re not limited to standard sizes or commercial profiles—you can route custom slots to match your own jig designs.
Need a longer run? No problem. Wooden T-slots aren’t limited by manufacturing lengths, so they’re perfect for large sleds, fences, or clamping setups. You can even adjust the depth and width to suit different types of hardware or homemade clamps.
Strength and Durability
This is where aluminum T-track has a clear advantage. In situations where downward clamping pressure isn’t available—like vertical stops or end-mounted tracks—wood just can’t handle the stress. It can crack or break under load.
But wooden slots aren’t weak by default. Jodee shares a clever trick: soak the side walls of the groove with thin CA glue. This seeps into the wood fibers and hardens them, creating a thin plastic-like shell. Follow that with medium CA glue, and the result is a surprisingly tough slot that can handle everyday use.
Still, when high pressure is involved or when clamping at odd angles, aluminum is usually the better choice.
When Aluminum Makes More Sense
Certain applications call for aluminum no matter the cost. Mounting stop blocks to the side of a crosscut sled fence, for example, requires the rigidity that only aluminum offers.
Other scenarios include jig bases where parts slide in and out frequently or where you want the long-term reliability of a metal component. If your fixture will be used daily or put under strain, aluminum offers a better return in the long run.
Why Wood Is Sometimes the Better Option
That said, wooden T-slots hold their own in many common setups. They’re perfect for stop blocks, adjustable fences, router table accessories, and low-stress clamping jigs.
They’re also great for temporary or one-off projects, especially if you need a fast solution without waiting for an online order. And for woodworkers who enjoy shaping their own jigs from scratch, the ability to customize dimensions is hard to beat.
Balancing Strength and Simplicity
Jodee makes a solid case for knowing your use case before choosing. If you’re working on a budget, or simply enjoy the DIY aspect of making your own tracks, wood is the clear choice.
But if the track will be taking a beating—or if you just want the convenience of pre-made components—aluminum can be worth the added expense.
Final Thoughts
The choice between aluminum T-track and wooden T-slot comes down to function and preference. Wooden slots are flexible, affordable, and easy to make in bulk. Aluminum is tougher and better suited for high-pressure applications or permanent fixtures.
Rather than siding with one over the other, Jodee shows how both materials have a place in a well-equipped woodshop. Choosing the right one just depends on the task at hand.
