The Enduring Appeal of Mortise and Tenon Joinery
As an experienced woodworker and craftsman, I’ve learned that the true beauty of our trade lies in the timeless methods that have stood the test of time. Of the many skills I honed during my apprenticeship in Japan, one principle I took to heart was the inextricable link between speed, efficiency, and quality. In the modern age, where disposable goods and mass-produced items reign supreme, it’s heartening to see that the age-old art of mortise and tenon joinery remains a cherished technique amongst discerning woodworkers.
Crafting strong, aesthetically-pleasing joints is no easy feat, however. The process of creating a square or rectangular mortise and a precisely-fitting tenon, with clean shoulders, can be time-consuming. But fear not, my fellow woodworkers – there are ways to streamline this process and unlock newfound efficiency.
Introducing the Tenon Cutting Machine
During my time in Japan, I had the privilege of working with a remarkable machine that revolutionized the tenon-cutting process: the Tokiwa Kogyo combination table saw tenon cutter. This ingenious tool featured a main shaft that connected the table saw blade on the left with a dedicated tenon cutting blade on the right. The adjustable table, movable fence, and depth adjustment rod allowed for lightning-fast and highly accurate tenon cuts.
The inspiration for my own tenon cutter project was born from witnessing the sheer speed and precision of this Japanese-made machine. I knew that replicating its functionality in a standalone tool could be a game-changer for my woodworking endeavors. With a beat-up old cross slide vise in hand, I set out to design and build my own tenon cutting machine, determined to streamline the process and take my joinery skills to new heights.
Advantages of a Dedicated Tenon Cutter
But why, you might ask, would one choose to build an entire tool rather than use a simple table saw jig? The answer lies in the distinct advantages that a dedicated tenon cutter offers.
For starters, the table saw can be an awkward and cumbersome tool for cutting tenons. Clamping the material vertically and engineering a sled to slide along the fence can be tricky. Moreover, the blade’s impact on the edge of the workpiece rather than the end can create some unnerving torques. The vertical orientation of the work also limits the height you can accommodate, and there’s always the risk of the jig coming out the other side and potentially causing injury.
In contrast, a tenon cutter like the one I built allows you to feed the end of the workpiece directly into the centered blade, taking advantage of the cutting action’s curvature. This results in a small, curved recess in the tenon’s shoulder, ensuring a tight, gap-free fit in the mortise. The precision of the lead screws and tolerances also allows for highly repeatable setups, enabling you to whip through parts with efficient workflows.
Designing and Building the Tenon Cutter
The real heart of my tenon cutter project was the ability to precisely position the workpiece, both horizontally and vertically, in relation to the blade. The cross slide vise I had on hand served as the perfect starting point for the adjustment mechanism, allowing me to design the rest of the tool around it.
The fabrication process involved two main stages: machining the custom parts and then constructing the frame to connect everything together. I chose to machine the frame tubes to length for a precise fit-up during welding, and I drilled all the mounting holes as indicated by the CAD model to ensure optimal alignment of the components.
After painting the parts in a sleek hammered grey finish, I added a metal blade guard and a dust collector to complete the assembly. The final step was wiring up the powerful 2HP Baldor motor and taking the machine for its first test run. I can’t begin to describe the sense of satisfaction I felt when I saw the tenon cutter spring to life, spinning up with minimal vibration and requiring only minor adjustments to square the fence and table.
Putting the Tenon Cutter to the Test
With the machine up and running, I couldn’t wait to put it to the test on some real-world woodworking projects. I’m pleased to report that the tenon cutter performed flawlessly, allowing me to complete nearly 500 tenon cheek cuts in less than half a day. The repeatability was excellent, and I could confidently depend on the consistent size of the tenons across all the parts.
One key upgrade I’m considering is switching to a dedicated ripping saw blade with square teeth. The nature of these tenon cuts means the blade teeth are cutting nearly perpendicular to the wood fibers, and a proper ripping blade would likely clear the chips more efficiently and provide an even smoother cut.
Mastering the Art of Tenon Cutting
As I reflect on my journey with this tenon cutter, I’m reminded of the immense satisfaction that comes from tackling a complex woodworking challenge head-on. The process of designing, building, and refining this tool has not only streamlined my joinery techniques but has also deepened my appreciation for the nuances of mortise and tenon construction.
Crafting precise, gap-free joints is an art form that requires meticulous attention to detail and a deep understanding of wood movement and grain orientation. By incorporating features like the undercut shoulders and the ability to precisely control the workpiece positioning, this tenon cutter has allowed me to take my joinery skills to new heights.
Sharing the Wealth of Knowledge
My hope is that by sharing my experiences and insights with fellow woodworkers, I can inspire others to explore the wonders of tenon cutting and joinery techniques. Whether you’re a seasoned professional or a passionate hobbyist, the principles and methods I’ve outlined can be adapted to suit your needs and skill level.

Leveraging Loose Tenon Systems for Precision Joinery
While the tenon cutter I built offers a highly-specialized and efficient solution for cutting tenons, there are other tools and systems on the market that cater to the needs of woodworkers seeking precise joinery. One such system that has gained significant popularity in recent years is the Festool Domino.
The Festool Domino is a versatile hand-held power tool that allows you to cut mortises in your workpiece, enabling you to join pieces using floating tenons (or “dominos,” as Festool calls them). This system provides a user-friendly and accurate way to create strong, reliable joints without the need for a dedicated tenon cutting machine.
However, the Festool Domino comes with a relatively high price tag, often ranging from $900 to $2,000, depending on the model and accessories. For many woodworkers, particularly hobbyists or those who only need this type of tool occasionally, this cost can be a significant barrier to entry.
Exploring a Cost-Effective Alternative
In my search for a more budget-friendly alternative to the Festool Domino, I discovered the Triton Duo Dowel Jointer TDJ 600. This tool, which I purchased for around $200, offers a similar functionality, allowing you to cut dowel joinery in your workpieces.
While the Triton Duo Dowel Jointer isn’t a direct equivalent to the Domino, it can be a viable option for woodworkers looking to achieve a comparable end result without the hefty price tag. However, it’s important to note that the Triton tool may require some modification and fine-tuning before it can be used effectively.
In my own experience, I had to make a few adjustments to the Triton Duo Dowel Jointer to get it working accurately for my needs. But once I had it dialed in, I found it to be a useful and cost-effective tool for my occasional use, especially for projects where a Festool Domino isn’t an absolute necessity.
Balancing Cost and Capabilities
When it comes to choosing the right joinery system for your woodworking needs, it’s all about finding the right balance between cost and capabilities. The Festool Domino is undoubtedly a premium tool that offers exceptional precision and performance, but its high price point may price it out of reach for some woodworkers.
On the other hand, the Triton Duo Dowel Jointer, while not a perfect substitute, can provide a more affordable option for those who don’t require the full capabilities of the Domino. The key is to carefully evaluate your specific requirements, your budget, and your willingness to invest time in modifying and fine-tuning a tool to suit your needs.
At the end of the day, the choice of which joinery system to use is a deeply personal one, based on your individual preferences, skill level, and the demands of your woodworking projects. By exploring the various options available and understanding the trade-offs, you can make an informed decision that aligns with your goals and helps you elevate your craft to new heights.
