Tuning pins undersized, where can I find sockets for my lever ?

Hello patrick,

I've problems with my camera, so sending you pictures of my piano will be a
bit complicated for the moment. but well, it is quite easy to describe. They
are like every normal pins but thinner. The usual shape is a cylinder, with
the top cut with four tilted flats. like if we intersected it with a very
pointy pyramid.

It's the same shape except that the outer diametre is 3/8", which is smaller
than the usual size, (and a 1/4" square at the top).
By the way, I finally have found the tuning lever maker (schaff), who said
me that they knew that such smaller pins existed, but they don't support it.
So, I've made a small adaptor that is more or less the size and the shape of
the pin, and get hold in a 11mm hexagonal wrench. This is extremely
unconfortable, and it took me all the night (till 8AM) to tune the whole
piano and raise it a little (my first tuning ever :-D ) and when I went to
bed, my hand and arm started to be awfully painfull. So the next step will
be to make a socket that goes on the tuning lever, which will be a problem,
since the screw is not a very common one, especially here in europe.

the fact that the piano is old and not going to hold for long, is the first
reason why I wanted to be able to learn tuning it by myself. I'm not rich
enough to pay someone to tune it every month. by the way, having to tune
frequently will train me, won't it ?

Tuning didn't seem to difficult, Well... It took time, I had to find a few
tricks to enhance my ear sensibility, but at had the feeling it was coming
quite easily. The problem is that I don't know if I'm just sooo
instinctively good that I find it easy, or just soooo bad that I can't hear
how bad my tuning was...

For my first tuning, I used kirnberger II temperament, and instead of
reproducing the middle octave to the others, I worked by check all octaves
by the same method. I don't know if it is something tuners usually do, but
it worked much better than matching the octaves. I don't have a problem with
the bass strings, which I can't discriminate very precisely. Is there any
trick for that ?

It may be possible that raising the piano to A440 will be a problem. I
didn't dare to raise it too much, but I have the feeling that I could raise
it more than I did. I was quite affraid in the treebles, but it seems (by
plucking it) that the tension in the strings is not too hard.

best regards,

Philippe

Hello Philippe,

The "problem" might be that the pins in the piano are (appart from smaller
size) even a different shape from the ones we usually find in newer pianos
than yours. If the frame is woodden, then your piano is sure VERY old. The
pins might even be of oblong shape. (If you want to send a picture of the
inside of the piano, i'm sure i can tell you).

On the other hand, it might be difficult learning tuning, specially by
yourself in such an old piano, since is not going to hold the tuning long
enough, you are probably not going to be able to tune it to pitch (a440
fork), and i doubt the action is going to work well enough... but anyway,
i shouldn't assume anything until i see the piano :)

With regards to your tuning lever, it is a professional model, so its a
very good choice you've done there.

Regards,

Patrick
