to shim or not

[John Fortiner]

The service manual for Baldwin pianos states very clearly that if the
sostenuto brackets need to be moved horizontally, do NOT shim them to change
their position horizontally.  Instead ( at least on older pianos without
adjusting screws ) they want us to bend the brass or aluminum brackets.
Bending brackets seems to me a hazardous method - especially on older pianos
where the metal may be brittle.  What harm is there in putting a thin piece
of card stock behind the bracket to shim it out if need be??
