How to Build a Pedestal Base

Pedestal bases are used for many different things.

One of the most common is tables. The larger the tabletop is, the larger the pedestal base will have to be. Tables are a necessary piece of furniture so it makes sense to learn how to build a pedestal base. Basic tools are all you will need if the lumber is cut at the retail store for you. A lot of glue is used to build a pedestal base, so remember to allow it to dry completely before moving on with the assembly or using the pedestal base for its intended purpose.

Place the 2-by-4-inch lumber on a worktable. Space the 13½-inch pieces apart so that when you place a 30-inch piece on them, it leaves a 3½-inch space in the center. Apply glue to the 13½-inch pieces and secure two of them to a 30-inch piece through the 30-inch piece (label this one #1) and two of them through the 13½-inch pieces. Secure them with the 2-inch drywall screws.

Place the 4-by-4-by-30-inch post on the worktable along with the four pieces of 3½-by-30-by-¼-inch plywood. Apply glue to one side of the post and place one of the ¼-inch pieces on it. Secure it along the edges with the ¾-inch brads. Repeat this on the other three sides.

Place the outside corner mold on the corners of the post to be certain of a good fit. Adjust the length if necessary. Apply a bead of glue to the corners of the post and secure the outside corner mold to the post with the 2d finish nails.

Place the 20-by-20-by-¾-inch plywood on the worktable. Mark the center of it and drill a countersink hole 3/8 inches deep with the 1-inch paddle bit. Apply glue to one end of the post, place the plywood on it and center it on the post. Tack it in place with the finish nails. Next, drill a pilot hole in the center with the 3/16-inch drill bit. Insert a 3-inch lag screw in the pilot hole and tighten it securely to the post.

Drill a countersink hole with the 1-inch paddle bit in the center of the 3½-inch space on the 30-inch piece that you labeled as #1. Make the countersink hole 1-inch deep. Next, drill a pilot hole with the 3/16-inch drill bit. Apply glue to the post and secure this piece to it with the lag screw. Apply glue to the 3½-inch space of the other 30-inch piece and secure it to the first one with the drywall screws.
