The parts of the pins fitting in the wrestplank are of considerable diameter and milled or screw-threaded to afford a better grip. The portion round which the string is wound is reduced, a collar being left at b<2>, while the squared head f is of the ordinary size. The end of the string is passed through a hole d communicating with the reduced part b<1> of the pin by an oblique channel in which the string lies.
