physically getting Hammers OFF shanks

[Porritt, David]

PS!  Ron's D is sounding great!  I just filed the hammers very lightly
and did some very light regulation on it then had to sit and play it a
few minutes!

  Hi Dave

   I routinely go thru a process of finding the optimal strike line when
hanging new hammers, so the ability to quickly remove them without
damage & then reinstall them is very important. .......Well obviously."
Even when I have done a thoro job of locating what I think is the
optimum strike spot, & hang the hammers I frequently find myself aurally
tweaking the location later during or after final voicing. The area in
question covers a large segment of the trebles so this tool makes quick
work of this process without damage to center pins & endless time
consuming heating of the shank & hammer head to persuade the glue to
give in. 

  I frequently receive  actions in the course of belly work that have
already been "rebuilt." New Renner hammers & parts or Abels etc.  Too
Heavy a hammer for the knuckle location part or hammers I don't like on
that piano or just to dang heavy period.

    Another scenario is I remove the hammers then relocate the knuckles
where I want them & prep the hammer of my choice & reuse the shanks. It
takes a shop grunt 3 hours to do this so recycling $00.00 shanks is a
good deal for 25 bucks labor & a set of knuckles.  It does Require a
slotting jig.  I also use your method of removing hammers I am putting
in the trash.

  Hey How's Ron N's D sounding?

  P. S I have  brand new set of Brooks bored & prepped Abels preped for
a 20 note Steinway.  

    Less than a few hours of play.  Make an offer...selling em cheap

	I am right now in the process of taking some hammers off shanks.
I have a hammer removing tool, but only use it if I want to save the
hammers for some reason (they're not totally shot and there might be a
piano around here with a lower priority that could use these.)  Most of
the time, however, I just cut them off as I'm doing now.  A hefty pair
of diagonal cutters will split the tail and then pull them off and throw
them away.  I've always found that faster than the hammer puller.  

	 

	How does this new tool do with the glue collar?
