Step 2: Preparing the Materials

Start by gathering your materials. You’ll need a half sheet of plywood as the main surface, along with other scrap wood for additional components. The hardware kit will include essential items like screws and the moxon-style vice handles.

Step 3: Cutting the Plywood

Use your circular saw or table saw to cut the plywood to the desired dimensions. While a table saw will make this easier, you can achieve good results with a circular saw as well.

Step 4: Building the Vice

The built-in vice is a key feature of this workbench. Using the inexpensive hardware from the kit, assemble the vice and attach it to the front of the workbench. This vice opens and closes smoothly, providing nearly 6 inches of capacity.

Step 5: Adding Dog Holes

Drill an array of dog holes in the work surface. These holes will allow you to secure your workpiece for sanding, routing, carving, or drilling, making the workbench highly versatile.

Step 6: Installing Popup Stops

Install popup stops at both ends of the workbench. These are useful for quick work without the need for clamping, making them effective for both hand tools and power tools.

Step 7: Adjusting the Height

The legs of the workbench can be swapped out to adjust the height for various tasks. This feature is especially beneficial for those with back or eyesight issues, allowing you to work at a more comfortable level.
