Hi Brian

   The brief answer to your question is that hammer makers get their bulk=
 sheets of felt from the felt maker and generally each sheet will general=
ly yield 11 or 12 sets of hammers when it is sliced up into strips. The w=
eight part comes in as to the overall weight of those large sheets. So, o=
ne of those sheets may weigh 12 ,14.15,16,18lbs. The important part for y=
ou means the higher the stated weight the denser thus heavier the felt. =20
      Also mahogony and  lighter weight vareiteies of maple can weigh rou=
ghly the same depending on wood densities within each give species. Ronse=
n now supplies the saepele( mahog.) as well as the light weight maple and=
 I can tell you the weights are so similar.

Hi all,

Speaking of hammers,...

I've noticed on numerous occasions when looking
at hammers in the supply catalogs that they are
available with several different moldings.  I can
understand that part of it, weight!  Hammers with
maple moldings would definitely be heavier than
ones made with (for instance) mahogony.

But what about the felt??  It is pretty normal to
see them available in 12 lbs., 14 lbs., and 16
lbs. specifications.

Does anybody have an explaination of specifically
what that means in practical terms?  Is it the
weight of the felt put into the press for the
entire set?  Getting real basic here, if I were
looking for a lighter (weight) hammer, would I
want to be getting the 12 lb. set instead of the
16 lb. set?  And vice versa, should I be getting
the 16 lb. set if I'm interested in a heavier
hammer?  I know that techs are getting much
fussier about individual hammer weight these days
and I'm wondering if I could be reducing the
amount of work simply by which set of hammers I
order.

I've never really heard much of an explaination
about this.

Anyone care to enlighten me a bit?  I have a
feeling I'm not the only one who's ever wanted to
know.  :-)

Thanks,

Brian T.
