[pianotech] Cosmetic aspects of filed hammers

[David Boyce]

Yesterday I tried hammer filing using a small Dremel-type tool for the 
first time. Hitherto, I've always used home-made sanding paddles.

I've been meaning to ask for a while,  what others do, if anything, to 
improve the appearance cosmetically when the top surface of the hammers 
is very grubby. I found yesterday that the dremel tool was quite good 
for that.

I am attaching two pairs of before-and-after pics. One from hand filing, 
and yesterday's with the little drill.  The angle of the photos makes it 
look as if all trace of grooves was removed, but actually that's not the 
case. Plus, the photos seem to exaggerate small unevenesses!

I have read in the past, of using dressmakers' chalk to brighten grubby 
hammer topsides, but that seems a laborious process and somehow slightly 
distasteful.

Best regards,

David Boyce
