John,
You said: "... and tripled the radius of the spring end."  In more detail
what/how did you do this?
Kindest Regards,
Garret

No, your "key buttons" are our chases.  My cradle is your repetition 
lever or whatever the latest nomenclature is.

The black soap was in the spring groove and had gone hard.  Besides 
that the curl on the end of the repetition spring has far too small a 
radius and wears a dent in the hornbeam.  I have cleaned out the 
muck, burnished the groove and tripled the radius of the spring end.
