I like this idea. I'll check it out next time I'm at the piano. Several
slotted, threaded brass rods screwed into the bridge top between unisons. I
wouldn't cover them at all. The bridge top doesn't have graphite and the
brass would look fine.

I was talking with Tim Geinert about the thread and he thought of the idea
of attaching a piece of flat brass to the front side of the bridge.
Accessible from the action cavity under the strings. Might be worth a try.
Easily reversible if it didn't work and if it worked and didn't look
atrocious, then I could epoxy it in place.

Thanks for your ideas.

Alan
