Micahel, others,

The "pry tools are available at Jahnn, the best version , with a handle
allow you to make the lever on another tuning pin (round space for that in
the tool) . The other one have a spacer at one end, I guess it is not really
a "pry bar, but some kind of hook that go around the tuning pin, I am sure
you know that one (but it looks like a German tool to me).

The coil lifter is a must you can work from above, or from under, ther is a
mobile mass that does the job (assuming the strings are not really too tight
on the pin, for the APSCO version of the tool I have)

BTW Terry, do you have more than one tip on this tool (for smaller or
thicker tuning pins) ?

Best regards.

  Hello Gordon. Just a couple weeks ago I leveled coils on a piano the was
likely restrung a good 50 years ago - an 1880s Knabe square grand. First of
all, the Mother of All Coil Lifter from Joe Goss - picture below. I guess I
should have put something next to it for scale, but it is twice the size of
the junkers from Schaff and it has a hardened tip. No coil will be unlevel
as long as I have this tool!



  Please tell me how this tool works? You cinch the coils up from
underneath, so I can't guess at the action required.

  Below is a picture of the horrible coils I was facing. I was afraid to
even try and tune it because so many of the strings were already getting
mashed down into the plate. The root of the problem on this piano was that
the holes for the tuning pins were drill about 20 degrees off of vertical -
the coils will naturally go down unless someone is determined to force them
up - at least temporarily.



  How many of you noticed that the coils are the wrong way round? I once
came across a piano where a cowboy had replaced a couple of strings this
way. I didn't notice it until the pitch went down instead of up...! Then I
had to re string the affected parts.

  Actually, I did not use Joe's tool on this piano - I use his too for
perfecting the coils. On this horror project I used the little pry-bar type
coil lifter available from the supply houses. I just let tension down on the
strings enough so that the coil would lift via the pry tool.

  Can't get this "prytool" in UK

  Regarding the becket - just take a pair of pliers when you let the tension
down and squeeze them puppies.

  I use a pair of long duck-billed - it "gets in there!"
