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.=20

I use a pair of long duck-billed - it "gets in there!"=20
