Hammer Boring

[Joe And Penny Goss]

Hi Matthew,
In the manufacturing process it is easy to put the upright hammer and shank into the butt assembly and adjust slightly where the hammer is in relation to the desired strike point. At the Yamaha factory they used a call that held a section of hammers spaces and angled. The worker only needed to dip the shank end into a trough of glue and place them as a section in the hammer butt holes.
Onky slight tweeking was needed to align the hammers to the strings.
VERY FAST

  I have become known as the man with many questions, so here is my next question.

  Why are grand hammerheads bored all the way through, but not verticals.  I do not know if every grand is, or every vertical is not, but I was just curious.
