C88 Hammer Position

[Mike and Jane Spalding]

Terry,

Only that life is so much simpler when you can lay things out in a straight
line.  I've never replaced hammers on a piano where the hammer line curves,
and don't know what you would use in place of a straight edge to align the
hammers as you install them.  Maybe replace all the odds, using the original
evens as guides, then replace the evens?

Low tenor should  be fairly tolerant of hammer position - how far do you
plan to raise the last few hammers?

Mike
