The blank is carefully selected. It must be in very good condition, which means it must not have obvious splits, cracks or any weaknesses. A damaged blank could shatter when it is revolving at high speed on a lathe.
It is important to remove the ‘corners’ of the blank. Attempting to turn a square shaped section on a lathe is very dangerous. The procedure for removing the corners is as follows:

   
Diagonal lines are drawn on the surface of the blank, in order to find its centre.
   
 
   
A circle is drawn, with its centre the crossing diagonal lines.
A bandsaw is then used to remove the waste material and the circular blank is ready for the lathe.
