Through experimentation, I have found that for this model of violin, the front of the sound post should be an accurate 0.125" behind the back side of the bridge. (This is typical for most violins)
The pictured tool is made of two layers of thin plastic stapled together. A notch is then cut out which locates the sound post. One piece is inserted inside through the 'ff' hole and the external piece shows the exact location of the sound post. An ordinary business card cut 2/3 through works to locate the front side of the post.
Here then is the completed violin, ready to play for the first time.
At this point, I have yet to put bow to strings.
The chin rest is easily attached with the two bottle screws; so If a different style chin rest is needed it is easily switched.
The sound post should be vertical, both side to side and front to back, and just to the inside of the right bridge foot.
The range of adjustment of the sound post is about +/- 0.01" from its ideal location. Power and tone color suffer when the post is away from this position. Both ends of the post should exactly match the curve of the adjacent violin plate as well. The growth rings should
be 90 degrees to the violin
centerline.
