I recently discovered a can of "Action Treating Solution" buried at the back of a cabinet in the shop.
The label say Dimethyl Silicone. My guess is that this was what was used to treat the keybushings in an
effort to reduce friction. Overkill anyway since the bushings on this 7 year old SS D were over-eased so
much that they needed replacement.
Anyone think this might have made it difficult for the hide glue to stick? Maybe the only reason the Titebond
liquid hide glue held is because I cleaned the mortises with Acetone.

Hi, all.
I recently needed to replace the balance rail bushings on a nine year old Hamburg D. This is a
piano in an auditorium that gets heavy use. Hammers/shanks/flanges and key end felts were part
of the replacement.
The original bushing cloth was white. Peter at S&S Parts Dept. said this is not available outside
the factory. So I put in the red cloth from Pianotek with hot hide glue.
While I was regulating the action with new h/s/f, the bushing started coming out. Upon examining
them, I found that the glue had bonded to the cloth, but not the inside of the mortises. I will have
to re-bush the set again, but the question is why they came loose to begin with. What is Kluge using
as an adhesive? They came out with steam normally so it is obvious it was a water soluble glue.
Anybody have any idea what was used and how to get the residue out of the mortises?
Thanks!
Dave
