Subject: Re: Wegman Tuning Pin System
As the (unofficial) spokesman for the Wegman piano (they were=
made in our town), I'll try to answer your question. The=
tuning pin system Wegman used consisted of a conventional plate=
with carefully drilled holes that the very short, smooth tuning=
pins would fit into. There was no pinblock, and the pins were a=
slip fit. The pull of the string in one direction would create=
enough friction on the pin so that it would stay in one place=
but still be able to be rotated for tuning. There is some=
controversey about whether the holes in the plate are oval or=
round, but either way, the pins jam and remain in one place.
Tuning is done in the conventional manner, changing strings=
is a bit tricky, but with a little practice is easy to master,=
as the tuning pin stays loose until there is tension applied by=
the string as it is tightened up. The system seemed to be a=
good one as pins never loosened, and I'm not sure why it has=
disappeared from the piano industry.
