HGTV expert Steve Watson gives you a list of materials and step-by-step instructions for refinishing a wood dining room table. You'll need a rotary sander, router with round over bit, stain, rubber stain brushes and a big box of rags. First, sand off the old finish. This will probably take about an hour or two, and you'll want to do it outside if possible. You might also consider routing the edges of your table to match other furniture in the dining room. Next, clean all dust from the table and apply the stain.
