AB = Minor axis
CD = Major axis
Use a string to act as a trammel and mark on the string distance equal to 1⁄2 the minor axis
Measure and mark another distance equal to 1⁄2 the Major axis
Move the string to various position so that mark C is always on minor axis and mark A is always on major axis
Mark various positions on the paper and make a fair curve through all the points to obtain the elliptical hole.
