          Daryl,
          Have you read this report by Michael Musial about a Jahn =
hammer?

          In regards to this an all other extension hammers. =20
              A few years ago I attended the class of Charles Faulk and =
his designing of the titanium tuning lever..  I purposely did not save =
his class notes so I could go through the same adventure of trial and =
error.  However he was my inspiration to go down this particular road.  =
It inspired me to work on my own along the same path.=20
               All extension levers have the same charactieristic.  The =
compression fitting is at the business end of the steel or whatever =
material is used.  No matter how long the shaft extends into the handle =
it is effectively rendered useless as the flex begins right at the =
compression fitting.   To me the logical solution for this is to make =
the lever not adjustable.  I have designed mine to fit as far into the =
handle as possible.  The more shaft and the more solidly it contacts the =
inside of the handle the more positive the hammer is going to feel.  I =
have chosen to use Schaff's lever shafts which accepts a variety of =
tuning heads.  In the hammers I have made, I have used not extremely =
heavy exotic woods on the bulk of the handle  but attached a larger =
piece of denser  wood to the end so a ball like end is able to be =
turned.  The handle is also not just uniformly round but shaped more to =
fit the contour of your partailly closed hand gripping it.  This way it =
gives you a choice of grips. 1.  Along the handle and close to where the =
shaft comes out of the handle or 2.  at the ball end and because of the =
extra weight of the denser hardwood it sort of acts like an impact type =
feel giving you a little more ooomph on moving tight pins. =20
              On the matter of the threads of the shaft I believe that =
Schaff plates the shaft after the threads are cut which can leave them =
sort of rough.  Finally the tuning head will cut through the plating and =
then the tips can be put on and took off easily.  I was always one to =
prefer a light hammer as I felt it allowed me to fel more what the pin =
was doing or not doing.. =20
              Whatver kind of hammer you get, it also needs to be gotten =
comfortable with through use every day on all kinds of pianos.
          Just my opinion.
