Build an Interchangeable Workbench Tool Mount
Workbench space is valuable, especially in a small woodworking shop. And while some bench-mounted tools are essential, they aren't necessarily used every day.
A bench grinder or machinist's vise, for example, needs to be securely mounted when you're using it. But leaving these tools permanently attached to your workbench can take up space that's better used for other tasks.
To solve this problem, I built a simple interchangeable workbench tool mount that allows several tools to share the same mounting location.
The system uses a plywood base that clamps into the face vise of my workbench. Individual tool platforms fit onto the base, making it easy to switch between tools as needed.
Best of all, the entire setup can be removed when I need the bench space for something else.
A Space-Saving Workbench Tool Mount
The idea behind this system is simple.
Instead of permanently fastening every bench tool to the workbench, mount each tool to its own removable plywood platform.
A single base remains clamped in the workbench vise while the individual tool platforms can be exchanged.
Two hardwood dowels in the base help position each platform consistently.
This makes it possible to use a bench grinder, machinist's vise, or other small bench-mounted tool in the same location.
When you're finished, simply lift off the tool platform and store it until the next time you need it.
Building the Interchangeable Tool Mount
The workstation consists of two main components: a fixed mounting base and individual removable tool platforms.
Both are made primarily from plywood, making the project straightforward to build.
Step 1: Make the Plywood Mounting Base
Start by laminating two pieces of plywood together to create a sturdy mounting base.
Once the glue has cured, cut a wide dado across the bottom face of the base.
This dado accepts the clamp bar that extends below the platform.
The clamp bar allows the assembly to be held securely in the face vise of your workbench.
Make sure the bar fits properly in your vise and that the assembled base is stable when clamped.
Step 2: Install the Hardwood Alignment Dowels
Next, drill two holes in the top of the mounting base to receive hardwood dowels.
Glue the dowels into the holes, leaving their ends projecting above the surface.
These dowels serve as alignment pins for the interchangeable tool platforms.
Chamfer the exposed ends of the dowels to make it easier to position the removable platforms.
The chamfers help guide the platforms into place without requiring perfect alignment as they're lowered onto the base.
Step 3: Make the Removable Tool Platforms
Each removable tool platform is made from a single piece of plywood cut to match the mounting base.
Drill two holes in the platform to fit over the hardwood dowels.
Chamfer the underside of each hole so the platform slips easily over the dowels.
This creates a simple locating system that allows the platforms to be exchanged without complicated hardware.
Step 4: Add Finger Grips and Mount the Tools
To make the platforms easier to remove, rout a finger grip along the underside edge of each one.
This provides a convenient place to grasp the platform when lifting it off the base.
Then securely attach each bench-mounted tool to its individual platform using appropriate mounting hardware.
Make sure the hardware doesn't interfere with the base or prevent the platform from seating properly.
Using the Interchangeable Workbench Tool System
Once the base and tool platforms are complete, using the system is straightforward.
Clamp the mounting base securely in the face vise of your workbench.
Select the tool you need and lower its platform onto the hardwood dowels.
The dowels help position the platform consistently.
When you're finished, remove the tool platform and replace it with another one.
Important Safety Note: The dowels are locating pins, not a substitute for positive mechanical retention. Secure each tool platform to the base so it cannot lift, shift, or rotate during operation. Check that the workbench vise, base, platform, and mounting hardware can safely resist the forces generated by the tool. Bench grinders, in particular, can produce vibration and require rigid mounting. Follow the tool manufacturer's mounting instructions.
A Practical Workbench Upgrade for Small Shops
Not every bench-mounted tool needs a permanent home on your workbench.
This interchangeable mounting system provides a simple way to keep occasional-use tools available without sacrificing valuable work space.
The plywood construction is easy to customize, and you can make additional platforms as your tool collection grows.
It's a handy workshop accessory that makes better use of limited space while keeping your bench tools ready when you need them.
