upright hammer bore angle

[John Ross]

It sounds like the hammers are too wide.
If everything is lined up properly, then what you will have to do is pare off the offending edges, to allow free travel.
I could carve a hammer, take a photograph, and send it to you, if you do not know, what I mean.

  Hello all:

  Could someone explain, or lead to a book that explains how to figure out hammer bore angle on an upright piano.  I have an issue going on with regard to new hammers on an upright but the whole bass section does not work.  They interfere with each other before the hammer gets to the strings.  I suspect it has to do with shaft length, hammer blow distance and other measurements, but as you can see, I just don't know the details.  The problem is.........its always the details that mess ya  up :)

  Thanks much
