Part 1: About the Sound Post Setter, and Choosing the Wood
A: The Sound Post Setter
The sound post setter is a small metal tool about 23cm/9"
long. The sharp point at one end is pressed into the post to hold
it for inserting into the instrument. The other end, which looks
like a hand, is for moving the post once it has been placed in the
post setters available here).
B: Selecting the Wood
The post is made of a dowel of spruce, usually about 5.5-6mm in
diameter for a full size violin. The post must be small enough to
fit through the f-hole at the notches, which is usually the widest
point. This is true for all instruments (from the smallest violin
to the largest bass). The grain should be fine, straight and even,
preferably matching the wood that was used in the top of the instrument.
So if the to plate instrument is coarsely grained, use a post with
wider grain; if it is filely grained, use a post that has closer
growth rings. (Sound post material available here).
