Speaking of hammers...

Hi David

  I liked your suggestion and would add notes no.28 & 52 as well. If a gu=
y /gal is used to working with a certain brand of hammer and weighing the=
 four or five basic notes really does give enough info to calculate kind =
of shaping prepping the job will require to hit your target weight.  Its =
not that tough.
 I buy all/most my un hammers completely unprepped from Ronsen and the 14=
lb.(sorry for the useless terminology Del) varieties don't vary that much=
 from set to set but I do weigh notes 4-16-28-40-52-64 on all sets just i=
n case one action might need to be on one side or the other and to antici=
pate the weight reqiuerments of job.
  To answer Andrews complaint as to "what's the use" his supplier could w=
eigh  entire sets of the same brand of hammer ( I bet that's what Wally d=
oes and allocates them to the action with" special needs" I think that's =
about as close to that as one is going to get. =20
    ALSO CONGRATULATIONS TO ANDREW for defecting from the PETRIFIED FELT =
HAMMER CLUB.  Isn't reality grand

    I did hang a set of Isaac hammers recently and the weight was really =
high even on cherry moldings.  I've found cherry moldings to be very inco=
nsistent in weight. Notes 16 at 10.5 grams ,40- 9.4  ,64-8ish.  The usual=
 great sound but all lot of whittling.

Andrew,
My suggestion to hammer makers is to take the average of a cluster of thr=
ee hammers around note #16,#40, and #64 .   This gives a very good indica=
tion of weight level in the area that is most played.  It's not hard to m=
ake an estimate of shaping and boring and tapering.  Wally Brooks provide=
s very good hammer weight information for his hammers.
So would you care to share the weight stats on the Isaac hammers? Levels?
