    m4a6qSASTKybJFAxuzT6_452CA67A-3FBE-4795-AF69-0C966CE2BF86.jpegI just serviced a 2007 Heintzman 132E upright (Chinese-made) with wandering centre pins - hammer, wippen, and jack. Probably damper flanges too, but I didn't check. They have what appear to be metal-lined bushings. Has anyone seen these before? Anything I should know about them when I send a quote for repinning and/or rebuilding the action?

    Is it an aluminum foil shim? Never seen that before. Flange replacement or rebushing should be in the estimate.
    Repairs are likely to exceed to piano's Fair Market Value.

    There is a normal cloth bushing in there, but there is this very thin metal layer on the outside. It could certainly be foil.

    I know I'm a little late here, but why would you recommend rebushing over repinning? If the centre pins are walking, it's the bird's eye that's the problem, not the bushing. So wouldn't just replacing the centre pins with larger sizes fix the problem?

    how do you roll tin foil that small ? Would be interesting to know if this exists in other pianos in their line and how many. The cost will add up if all of the centers need new bushings.

    Are you absolutely sure they are cloth bushings? Looks an awful lot like this early 80's Steinway Teflon bushing to me. 

    Photo is a little hard to see but the Teflon is encased in metal.

    Yeah, it's definitely cloth. The metal bit can pop out showing red bushing cloth. I have been trying to talk to people who have worked on a lot of Heintzmans or have been involved in the factory, and no one knows about this. It's almost like someone in the factory was experimenting with something without telling anyone.

    Are you sure the metal is not from some kind of extreme flaking of the pin? It has been a while since I first saw your picture, but that was my first thought.

    it may have been an attempt to prevent the pins from walkout and to keep the bushings from getting pushed out during repinning- a sort of retainer. do you have a picture of one popped out of the flange ? how much bigger is the hole that holds the grommet and felt ? .

    it is on both an upright hammer flange and grand flange so maybe this was a bad batch of action parts that they decided to jerry rig to save the part . If there are walking pins all over its going to be a major job to repin and rebush . before jumping into this quicksand you should experiment on some - maybe the birdseyes are also oversized.

    Maybe it's a secret new process that will revolutionize the piano industry and this was a test piano put out into the field for future research and data collection. 

    Or it could be a hidden transmitter sending your every move back to the factory.  Watch out!

    This upright is the only piano that I have seen this with - the picture of the grand flange was from a Steinway. And this is the only other picture I took:

    The metal isn't from flaking, it's more like a foil washer.

    the grand flange did look like a teflon so i misspoke. was this thing only on the ends of the felt or was the bushing cloth inside it ? could this be some type of tubing that is used to insert the bushing cloth that someone forgot to remove ?

    Still think it's a secret transmitter tracking your every move.
