Round the edges of the two-inch thick oak plank using the router. Then sand the top, sides and bottom using the medium-grade sandpaper and sander. Sand the leg posts using the medium-grade sandpaper, too.
Drill holes into the bottoms of the leg posts for the wheel casters using the power drill and wood bit. Attach the leg posts to the two-inch thick oak plank using the power drill and wood screws.
Stand the table upright. Paint a layer of wood glue on the table top. Get extra glue over where the screws for the legs are located. Place the oak veneer onto the table and press down firmly. Clamp the veneer onto the table top using the C clamps spread out evenly around the perimeter of the table. Allow to dry for 48 hours.
Remove the C clamps once the glue has dried and cured. Use the sander and fine-grade sandpaper to blend the edges of the table so the plank and veneer look like one piece of wood. Sand the table legs lightly for a smooth finish.
Stain the table and legs using the wood stain of your choice. Allow to dry overnight and then varnish the table with high-gloss polyurethane. Again, allow to dry overnight.
Turn the table on its side and screw the wheels and casters into the holes you created for them in Step 2. Turn the table right-side up and it is ready to use.
