Initially, the wood is turned on the lathe machine. The block of wood is inserted to lathe machine and then it is turned to create the long wood stick in circular shape. The inner part of stick is removed by piercing it with a sharp edged file. The body part of Nadaswaram is made into a shape of a pipe by removing the inner wood pulp. Then the hollowed wooden stick is smoothened and cleaned with normal water.
A straight line is then marked on the pipe using a thin rope which is coated with lime stone powder. The artisan drills seven holes using a drilling tool on the basis of the white line mark created by the rope. The seven holes are accurately drilled maintaining equal distance between them.
The base part of Nadaswaram is a large flaring bell. This is made of wood by turning it on the lathe machine. Upper part is said as mouth tip and made of reed. Both, the flaring bell and the reed tip are made separately and fixed to the body of Nadaswaram. The final product is checked for proper tuning before sending it to the market.
