I don't necessarily want to - it sort of  complicates the process.  But it
does allow the string to meet the pin at an angle that keeps the coil from
loosening, while preventing the string from climbing up the coil.  I have
sometimes varied the angle to suit the individual piano.  What angle do you
use?
