It is done by drawing two ellipses one centered in the other. One ellipse is the width of the thickness of the root diameter of the screw with a length that fits the root diameter at the pitch you want to gain per cycle. The other width diameter is the inside diameter of the tube the screw runs in less some clearance.

To cut a correct thread on the lathe, it is necessary first to make calculations so that the thread will have proper dimensions. The following diagrams and formulas will be helpful when calculating thread dimensions. Example: Calculate the pitch, depth, minor diameter, and width of flat for a ¾-10 NC thread. P = 1 / n = 1 / 10 = 0.100 in.
