[pianotech] Gunk on guide rail bushings

[Greg Newell]

Richard,
	I've not seen it before but I'm wondering about the seemingly good
amount of clearance between the wire and the bushing. Could it be that the
cleaning and application of your chemicals only disguised the real problem?
Could it be that the wires are leaning on one side of the bushing too much
and causing the slow return? Just a thought. The seemingly large amount of
clearance makes me wonder.
Best,

Greg Newell

List, this is a brand new piano, made in USA. Cleaned a black substance off
of damper wires which were returning slowly or not at all.
Looked similar to center pin issue in Asian pianos.
Anyone see this before? I have more pics as well. Reamed bushing and used
clp and ironed bushing and so far so good.
