Fig. 1 shows part of an unfinished needle consisting of a gold &c. stem a, into one end of which is fused a piece b of osmiridium or the like. The tipped portion is then ground down to the form shown in Fig. 2, and polished. It is advisable to fix the needle always in the same position in the needle-holder of the soundbox, and any suitable means for ensuring this are used.
