Building an Aluminum Frame Table

Measure the length, width and height of the desired table frame. For instance, the length and width of a dining table varies, but the standard height is 29 inches, according to the Highland Woodworking website. Similarly, the standard height for an end table is 20 inches tall. A workstation table may be 26 inches high for comfortable use.

Cut your aluminum tubing into two lengths for the long edges of the table, mitering each end to a 45-degree angle using a combination square.

Cut two more pieces for the short edges of the table. Miter the ends of these to a 45-degree angle.

Set the aluminum lengths into a rectangle and weld the mitered edges to make the top frame edge of the table.

Cut four pieces of aluminum to your desired height for the table legs.

Clamp the legs to the frame and weld them into position at the edge of the frame corner. Corner clamps will help preserve the correct angle of the legs as you weld them to the top frame portion.

Measure and cut four lengths of aluminum to serve as stabilizers at the lower edge of the table frame. Because aluminum is a lightweight and flexible material, these additional supports will keep the frame from wobbling.

Cut a V-shape at the ends of the lengths with a metal saw to allow the diagonal lengths to fit against the legs.

Clamp and weld the diagonals into position.

Grind the welds smooth with 80-grit abrasive pads to create a smooth appearance on the surface of the metal.
