For my technical on tuning levers next week I'm planing on taking my =
laptop.
I can show pictures of some newly designed tuning levers to the other =
members.

If anyone has any pictures they could send me by e-mail
I will be glad to show them.
ddurand@kc.rr.com

I have some good pictures of the Juan tuning lever now.

Thanks

    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.
