[pianotech] Bore angle

[Paul T Williams]

Glad I can help.  I still feel so "new" after 17 years! that I'm always 
learning something, and whatever I can contribute makes me feel a little 
more worthy...  Sounds like you're doing the right thing..even changing 
angles  at really small degree changes...  or less than 1 degree, but 
maybe that's too anal...just for looks when it comes to that.

Thanks for the information and the humor.  It’s what I need to lay out the 
sweep in the middle octaves, going down to zero degrees 3 hammers at a 
time.

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!) to 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 
been 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 that reply.
