I've been boring my own hammers for quite
a while; now they know all the jokes and won't laugh at them anymore.

I do this too, Paul. 



The smoother transitions also look a bit  sharper.  Wally Brooks,
who I have bore the Abel Naturals I get from him are very nice..He may
have a good guideline for you all to follow if you want to do your own.
 I find the price I pay for having him do it saves me money, and mostly
time (but...time is money) in the long run.  There's just too many
pianos to care for here at UNL (I'm by myself with 106!  I know...waaaa!)0Ato take several hours to measure and bore my own.  He does a great
job. I have at least one set of blank Abels here in the shop that I'm not
sure I will ever use (in case anybody's interested in purchasing....contact
me off line if you want)  I'm pretty good at boring, but just don't
have time to do it...I won't bore you with any more details!  ;>)

1-26: 5 1/2 degrees right

27-33: 9 1/2 left

34-39: 7

40-46: 4 1/2

47-53: 2

54-88: 0



These are factory specs. Adjust accordingly. I always add more angle breaks,
about every 3 hammers. Makes smoother transitions.

A 1942 Steinway “ L” action is in the shop for repairs.  It does
not have any hammers.  The short explanation is that it was under
water in a flood about 22 years ago.  The instrument is just about
finished.  So far, I’ve bee
n able to find the answers I need in my
records.  I see know that I need to  record the bore angles I’ve
used.  To be clear, I’m referring to the angle of  the hole
that aligns the hammer (somewhat) to the angle of the strings.


  

This piano has the accelerated action; 26 note bass; 28 notes on the treble
bridge through agraffs; the rest under the capo bar.  I vaguely remember
all the bass notes at one angle, and the first note on the treble bridge
is the beginning of a decreasing angle through the middle (agraff) section
that comes to no angle for notes in the capo sections.


  

Thanks to all th at reply.
