A wooden table can, after time, become wobbly and unstable when joints connecting it to its legs loosen. When this happens, there are ways to tighten these joints and stabilize the table.
Step 1 – Locate Loose Joints
Before you can stabilize a wobbly table, you'll need to identify parts of the table that may be loose or broken. Set the table upside down on its top and examine each of its legs where they are connected to the table. Look for loose bolts or screws that can be tightened or joints that have become unglued.
Step 2 – Tighten Bolts and Screws
Use an adjustable wrench to tighten nuts on joint bolts where legs are connected to the table. If bolt nuts have become lost, replace them. Bolts that are loose in their bases can be tightened by replacing with bolts of a larger size. Tighten or replace screws that keep joints tight. If screw threads have become stripped, replace the bolts. If necessary, drill new guide holes or use glue to hold them in place.
Step 3 – Repair Glued Joints
Where glue in leg joints has become defective, remove the leg, sand the joint smooth, apply new wood glue, re-insert the leg, and allow the glue to dry. Remember to put down newspaper or something similar to keep the wood glue from touching the floor if you're not working in a garage or work space.
