hairspray hammer hardner question

[Roger Jolly]

Hi Juli,
              To clarify.  Hammers need to be correctly shaped with 
no significant grooves before any artificial hardeners are used, Also 
hammers need to filed and fitted to the strings before any 
significant amount of needling is done.
After heavy needling, some reshaping and string fitting is needed.
Hammer filing is an art, and it has to be learned , experience will 
tell you when to just follow the contour of the felt, and when to 
make the hammer a little more pointed..  There are several techniques 
for shaping hammers .

Needling to obtain a brighter tone is usually done at the 8-9 o'clock 
zone, and needs to be done very deep. 10-15mm.

My final step on ALL voicing/ reshaping jobs, is support the tails of 
the hammers and give them a firm ironing with a small travel 
iron.  The iron is hot enough to press any loose felt, firmly down, 
but not hot enough to discolor the felt.
This operation will brighten up the hammers quite a bit.

Don't be shy about being a rookie.    I am still learning.

Regards Roger
