Hi Paul 
  The Bass on Models s,m,l,& o,is 5 1/2 degrees. The treble spec is in the shop. Manana. OK?

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.
