voicing tracks?

[Michael Musial]

Hi

I looked at a new Boston grand today.  It was just delivered and the 
customer is complaining about a lack of power especially in the tenor.   I 
had to agree that there was no ~bite~ at all when played forte. The hammers 
sound over-voiced.  I took the D4 hammer and shoe-shined the surface, packed 
it by hitting it with the voicing tool handle, and also ironed the thing.. 
it helped a little but it came nowhere near what the customer or myself 
would find acceptable. Pushing my thumbnail into the side of the hammers 
barely left an impression so the hammers seem pretty hard.

I observed strange marks on the hammers that I do not remember ever seeing 
before.  They are parallel lines running down the keyboard side of the 
hammers surface.  On very close inspection I see some needle holes in the 
lines.  I have posted a picture of this on the web...

Is there some kind of tool that may have been used to cause this or do the 
hammers come out of the factory like this?

Thanks for any help!!
