   Point well taken. What I do know is that at least with my particular h=
ammer supplier a 14lb. weight felt on mahog. molding is lighter than the =
16 lb. version which indicates a denser felt. Yeah I know the wood weight=
 can vary but I've done this a few times and know what to expect. Know th=
y hammer supplier.
  Maybe suppliers should refer to there hammers as light medium and heavy=
 ,at least there would be less confusion....naaaaaaahh

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

Not necessarily. One part of redesigning the Baldwin 743/5 scale (the Ham=
ilton) included a change from a 9# hammer to a 12# hammer. Shortly after =
the new design was introduced a competitor also began advertising a 12# h=
ammer though to me they didn't look much different than the original. I l=
ater found the competitor has simply increased the size of the sheet of f=
elt they started with and cut a couple of extra sets of hammers from it. =
The actual hammer was unchanged but the brochure specification was change=
d to confuse the innocent.

The specification 12#, 14#, 16#, or whatever is meaningless.
