Steinway hammer Bore Angles

[Erwinspiano at aol.com]

Hi Clark
   I have a list with all the original bore specs that came from  a stwy 
source.  There is nothing on it remotely close to this except I  believe all bass 
hammers are 5.5 degrees. The first tenor is probaly 10  degress.  I can look 
tomorrow if you need to know more than this.

Hello, Listees!  I have a question that  I want to ask about the boring 
angles on Steinway grands.  I have a 1904  short A that does not have the original 
hammers on it, and the ones that are  there have barely any angle (Maybe 2 or 
3 Degrees).  The strings are at a  15 degree angle to the stretcher.
    I looked up Newton Hunt's  posting of published hammer boring specs in 
the archives, and the only bass  hammer angles for S&S that I saw were 5.5 
degrees for an L and B, I  think.  I bored a couple samples at 8, 9, and 1 at 10 
degrees, and  concluded that 8 would work.
    Any thoughts on this?  I  looked at a Baldwin R, next to it, and they 
looked to be about 10.  What  do you all use?
