On this note, in a recent conversation I had with Wally Brooks, he was =
commenting on how sets hammers of a given weight (e.g. 16lb) will vary =
considerably and to let him know what ultimate hammer weight I was =
shooting for so that he could select a set that was heavier or lighter =
depending on my need.  More evidence that the lb. designation refers to =
a range of actual hammer weight.

     Point well taken. What I do know is that at least with my =
particular hammer 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 thy 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 generally yield 11 or 12 sets of hammers when it is sliced up into =
strips. The weight part comes in as to the overall weight of those large =
sheets. So, one of those sheets may weigh 12 ,14.15,16,18lbs. The =
important part for you 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 Hamilton) 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# hammer though to me they didn't look much different =
than the original. I later found the competitor has simply increased the =
size of the sheet of felt they started with and cut a couple of extra =
sets of hammers from it. The actual hammer was unchanged but the =
brochure specification was changed to confuse the innocent.

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