[pianotech] Steinway back checks

[Mike Spalding]

Larry,

Some clarification is needed.  I believe current design is shorter than 
their previous long-time traditional design.  Are these backchecks even 
shorter than the new short design?  And, what exactly needs to be 
improved?  Is it that the buckskin is seriously worn?

In my experience, the short checks are as good as the long checks, with 
the advantage that they are less likely to interfere with the sostenuto 
blade.  Recover vs replace is a personal decision; I prefer 
replacement.  Steinway backcheck wires are splined at both ends, not 
threaded.

hope this helps

Mike
