Each hole has a length of 3.12 cm , three on the circumference of the plane of revolution but inclined 600 to the tangent of the circular revolving plane, three in the center  of the upper half pointing upwards at 600 to the vertical. Construction These revolving branch are made up with help of sand casting, die casting of grade 3 of IS 292, Hot forging of Grade 1 of IS 291, Gravity die casting of
