    I think that about covers it....

I find it some frustrating that in this so-called modern age with our =
sophisticated design techniques, our computers, our automated tooling =
and machinery that shameful excuse for a keybushing is the best we can =
do. Somebody actually spent time and money on this ridiculous thing. =
Somebody should have been ashamed of themselves but probably didn't know =
enough about the real piano world to be so.

The traditional key bushing certainly needs improving, but that atrocity =
was, and is, an affront to our industry and to the buying public.=20

Then consider, in the mid- to late-1880s a small piano maker in St =
Petersburg, Russia came up with this:






Beautifully made. Precisely detailed. Leather bushed. Fully adjustable =
-- those are two nicely and finely threaded screws going in from the =
side and those are two pins going down from the top neatly fitting in =
machined grooves in those screws. And, yes, they are still fully =
functional after some 125 or so years.

Ain't progress grand....
