I do know the Steinway stringing felt bundles come with adhesive backed cloth. It's pricey, but its also precut for each model. Saves a lot of time.

All of the bushings came off cleanly with no felt or glue left on the button and the felt that came off had a definite layer or ...I don't know how to describe it but it was remarkably like any self stick product. When I do the other M that we got at the same time I'll pay more attention to it. Of course I'm sure it came out of the Kluge plant. dave David M.

I have a 3-4 year old M at UNM, and it has normal key bushings. I think that in manufacture of key buttons, they tend to use a cloth with heat sensitive glue pre-applied, and then heated cauls activate the glue. If there was a malfunction where the cauls weren't hot enough, or not given enough time, maybe you'd get something similar to what you describe, a cloth with a fairly thick glue "backing" sitting in the key button mortise. Except that the material would be felted cloth, not the nameboard stuff, which isn't woven and isn't very dense. Could this be the case? I simply can't imagine any piano (or key button) manufacturer using self adhesive nameboard felt in this application. Well, I guess I can imagine it, but it seems pretty unlikely.

Same self-stick felt on all buttons though the guide rail bushings were "normal". This piano is in a practice room for piano majors. Four years is not unusual to need bushings in that case. Those pianos are played long and hard - especially hard! We have another M purchased at the same time but I haven't rebushed that one yet. I'm sure I will soon. dp David M.

Self stick nameboard felt? Were those the original factory bushing in the keybuttons? Or had it been previously rebushed.....? Or were there two kinds of felt on the keybutton? (Its just hard to believe keys would have been rebushed within the first four years... (Either confused, or incredulous, or perhaps, both~) ~Kendall PianoFinders www.pianofinders.com e-mail: kenbean at pianofinders.com phone: (925) 676-3355 Connecting Pianos and People Kendall: You asked how many still use self stick nameboard felt. This summer I rebushed the front and balance rail bushings on a 4-year old Steinway M and while the guide pin bushings were traditional, the felt on the key buttons was clearly self-stick felt! It was the exact same stuff as the nameboard felt. Fortunately it came off well - the sticky stuff stuck to the felt not the button - but I had certainly never seen that before! dave David M.
