How do you cut external threads using hand dies and the method of fixing and adjusting the dies to give the correct thread fit?

Answer 1

To cut external threads using hand dies, first select the appropriate die for the desired thread size and pitch. Secure the workpiece in a vise and apply cutting oil for lubrication. Place the die over the end of the workpiece and ensure it is perpendicular; then, turn the die handle clockwise while applying light pressure. Adjust the die using a die stock if necessary, ensuring it is set to cut straight and to the correct depth, checking the fit frequently against a matching nut to ensure proper alignment and thread quality.
