A round dining table is more challenging than a rectangular one — mainly because of the circular top. But with a simple router jig, you can cut a perfect circle every time. Here is the complete process.
Gluing Up the Table Top
A 48″ round table top requires a glued-up panel from multiple boards. Use 2×6 or 2×8 pine boards, jointed edges, and Titebond II glue. Clamp firmly and let cure for 24 hours before cutting.
Cutting a Perfect Circle
Make a router trammel jig: a strip of 1/4″ plywood with a hole for your router bit at one end and a nail pivot at the other. Set the pivot-to-bit distance to your desired radius (24″ for a 48″ table). Tack the pivot at the centre of your panel and route the circle in multiple shallow passes.
Pedestal vs Four-Leg Base
A pedestal base (single centre column) is the most popular for round tables — it leaves all four seat positions unobstructed by legs. A four-leg base is simpler to build but positions legs at the corners, which can interfere with seating.
