Build a Router Table by Upcycling a Kitchen Countertop

Overview

Twenty years ago, I barely had enough money for a router, much less a router table. So I built a quick, crude version from a hunk of old countertop supported by steel rails from a bed frame. I always intended to upgrade, but when I test drove other tables, I always found that I liked my homemade one better. It’s tough, easy to take to job sites and easy to store. But my favorite feature is the screw-on fence face. In two minutes, I can switch to a face with a larger hole for larger bits or a super-tall face for vertical routing. And since it’s replaceable, I don’t mind driving screws into it to secure featherboards or guides.

Over the years, I’ve built three of these tables—including an 8-ft. version for making long trim. The only tricky part is cutting the hole for the router plate, so this article will focus on a goof-proof method for that. For the rest of the project, cut and assemble the parts as shown in Figure A.

The table

The first step is to cut up the section of countertop. Some countertops have a hump just above the rounded front edge. If yours does, you’ll have to cut off a couple of inches and lose the finished front edge. Next, cut off the backsplash. Lay the countertop upside down and clamp on a straight board to guide your circular saw. You can make the other cuts with a circular saw or table saw. Keep in mind that saw teeth leave chips as they exit plastic laminate. To avoid chipping, cut with the laminate face up on a table saw or face down with a circular saw. A cut laminate edge is sharp enough to slice skin. To dull those sharp edges, make a few quick passes with sandpaper.

After the table’s cut to size, create a hole for the router insert plate. Place the insert plate 3-1/2 in. from the back edge of the table and build a guide around it (Photo 1). My guide is 1/2 in. thick; perfect for a 1-in.-long pattern bit. For a shorter or longer bit, use thicker or thinner material. Before cutting the groove (Photo 2), set the router bit depth. Stack two scraps of the guide material and the plate. Set your router on the plate and adjust the depth. To finish the hole, cut along the inner edge of the groove (Photo 3).

The fence

Build the fence as shown in Figure A. Assemble the fence with screws and glue where particleboard meets particleboard; screws alone where plastic laminate meets particleboard. Drill pilot holes and use coarse-thread screws; fine-thread screws won’t hold. To cut the slots in the fence base (A), drill 1/2-in. holes and then cut with a jigsaw. Two of the fence brackets (E) are double thick. To make them, glue scraps together back to back and then cut them to size. The size of the dust pen hole depends on the size of your vacuum hose. I bought a rubber vacuum hose adapter and cut off the stepped end. To fasten the fence face, drive 1-1/2-in. screws through the backer (B) into the face. Before you drill the T-nut holes and install the T-nuts (Photo 4), mark their locations using the fence base as a guide.

Choosing a plate

Insert plates made for router tables start at about $30 for a basic model like the one shown here (Rousseau 3509, available through our affiliation with Amazon.com). Search online to browse a huge selection. For about half the price, you can also make your own plate from an acrylic sheet (at least 1/4 in. thick; available at home centers). Despite my legendary cheapness, I prefer the manufactured versions; better results, less fuss. My one complaint is that they’re not always perfectly flat. But when I sentence them to a couple of days of corrective clamping, they flatten nicely.
