If the hammers could be made of black vinyl, that would be good as  
long as they are flexible enought to install.  Same material we use  
now for the sub, but black.

No Ron,

As far as I am aware there are no shore strength specs available.
The only properly made print hammer was done in Canada
but I no longer can find the example Dave sent me.
I put it in such a safe place... Have you ever done that?

George is probably right in that there are modern materials that might
work.
I am hoping to get a good recommendation from Mercer with the sample
that Wayne Durkee sent me.

Don do you have any more specs on the print hammer?  I'm looking for
a Shore strength spec if you have it.  There may be a simple solution
and
inexpensive to boot, I just need to find the right material strength.
