[pianotech] string hook

[Allan]

I understand, but my mechanical intuition tells me that it must be easier to
precisely apply the required pull with a lever than without. The string will
not go further up than when it is properly straightened at the exit of the
agraffe.

The amount of force required must be variable according to the different
string diameters.

Have a good week everyone.

Hi, Allan:    

    Joe Goss wrote that his tool is not made for leveraging.  I took a look
at mine, (short memory), and it's made to simply pull on.  As a matter of
fact, there is a limit to how much the string will move.  You really don't
need a whole lot of leverage to do the job.  I've broken strings doing a
"leveling" job with a simple hook, with no leverage.  That's the danger
involved- getting too aggressive with the process.

    The plier I'd like to see would rest on the agraffe and use a squeeze
action to lift the string.  What I'm after is a consistent pulling force.
Maybe some kind of adjustable spring involved which would limit overpulling
and quantify the amount of force (make it repeatable).

    Just some ideas...

Wim : "The Hart spring hook should not be used on strings. It should only be
used on springs," I would like to know about the sPring hook as well
 
Paul; " I don't know of a Hart string hook, but he has a s
 pring hook that is very handy for manipulating various springs.  Not used
for string leveling.  Joe Goss has a string levelling tool [.]  These string
levelling tools are very efficient because of the leverage against an
agraffe"      "Part of the fun of piano work is coming up with a tool of
your own, or modifying one you bought and make it better.  [.].  I've always
thought of somehow using some kind of dedicated plier to do this job.  Maybe
someday... >
 
You made me think I can ask my brother Mark to make tools to my
specifications. The nice thing about Joe's one is that the height of the
hook itself seems adjustable. Pliers? Describe it, we will 
 make it! Who is "he" who has a sPring hook?

 

Joe; "Neven Essex is the guy who came up with the idea of using the 

leverage lifter and tried to convince me to change my design but we could
forsee missuse and damage to the agraffes, strings and other issues by over
agressive use and strong techs."

 

I would like to understand what are your fears of missuses.  Isn't your tool
taking leverage against the agraffe (or the area between the tuning pins and
the agraffe)? I want to buy it. Will you be at Grand Rapids, can we buy your
tools there?

 

Thank you for your interest all of you.
 
We love tools, don't we?

Allan,

I made mine.  Piece of old brass pedal rod, cut to length, drill two holes
for the top end of the wire, insert wire and bend over to lock.  Add a
rubber foot, file a little groove in the top and buff to smooth the edges
and you're in business.

Thank you Paul and William. The tool in the pictures is different from the
tool sold by Mother Goose, which doesn't show a rubber "foot". Is it
available for sale somewhere or should I just try to make one?
