I had a Chinese made Hobart M. Cable grand af couple of weeks ago, that had a key that would stick after it had been played for 15 to 20 minutes. Even then it would not be sluggish every time it was depressed. I pulled the action and noticed the jack did not seem to return correctly now and then. I re-pinned the jack and it seemed to take care of the problem. Not sure, but I'm thinking there was a microscopic burr on the old pin. I've heard of these, but first time I've encountered it, if that is what it was. Guess a small microscope in the tool case would be in order. : >) Regards, Ron Alexander -------------- Original message from pianotech-request at ptg.org: -------------- > Send pianotech mailing list submissions to > pianotech at ptg.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://ptg.org/mailman/listinfo/pianotech_ptg.org > or, via email, send a message with subject or body 'help' to > pianotech-request at ptg.org > > You can reach the person managing the list at > pianotech-owner at ptg.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of pianotech digest..." -------------- next part -------------- An HTML attachment was scrubbed...
