If you use plywood any thinner than 3⁄4 in (1. 9 cm), it will not be able to support the weight of the router. The size of the plywood can be increased or decreased depending on how much tabletop space you want.

If you have a pocket hole guide, you can attach the boards together in the corners discreetly with pocket screws.

Use screws less than 3⁄4 in (1. 9 cm) long so they don’t break through the tabletop. If your frame still fits loosely to the tabletop, use another metal bracket in the middle of each board.

Having the table at waist height allows you to work comfortably without having to reach far. You can also make the table the same height as your current workbenches if you’d prefer.

Use wood glue before you put in the screws the legs to have extra security.

Use a level and clamps to hold the support in place while you screw it in. If your wood cracks, squeeze wood glue into the gap and clamp it tight so it is secure. [8] X Research source

If you want more counter space to hold tools or materials, make the square closer to the front. Otherwise, you can place the hole in the center of the table.

Some routers may be different sizes and require a smaller or larger hole. Measure the width of your router to see if you need to make any adjustments.

Cutting the holes in each corner gives you a starting point for when you start sawing and helps relieve some of the pressure when you make your cuts.

Work slowly with your saw so you don’t travel outside of the lines.

Wear eye protection and a face mask since the router will produce a lot of sawdust. Make guides out of spare 2 in × 4 in (5. 1 cm × 10. 2 cm) boards and clamps to prevent you from going outside of the edges you’ve marked.

The router will make curved corners on the tabletop, so you need to round the acrylic so it matches.

To find the center of the acrylic, use a dry erase marker and a straightedge to draw lines across the sheet from one corner to the other. Turn the acrylic sheet and make another line between the 2 remaining corners. The center will be where the lines intersect. Wipe the lines clean with a dry cloth.

The holes need to line up or else the router will not properly fit under the table.

To make the screws flush with the acrylic, use a drill bit the same diameter as the screw heads. Drill 1⁄8 in (0. 32 cm) down in the holes you just made.

If you ever need to remove your router, lift it out of the hole and unscrew it from the acrylic sheet.
