Step 5: Solder the Corners

When the soldering gun is hot enough, hold it in your dominant hand and pick up the coil of lead-free solder with your other hand. Place the straight tip of the coil on the rough zinc edge at one corner and touch the tip of the gun to the coil to join the metals. For a smooth and uniform joint, hold for 3 to 4 seconds, then remove the coil before removing the tip of the gun. Repeat on each corner of the table. Use a metal file to even out the corners.
