Tom, I guess that was part of my question, as well.<G> I'd like to retain the flanges, if possible, but there are issues. Still waiting for some of those eye opening answers.<G> Joe ----- Original Message ----- From: Tom Driscoll To: joegarrett at earthlink.net Sent: 7/26/2011 6:16:10 AM Subject: Re: [pianotech] Chickering Grand Hammer Flanges? Joe, I don't know the answer, but I do have a related question about frozen drop screws on these flanges. I've had numerous experiences where they just break off . So my somewhat related query is will heat break them loose ? Awaiting our crews response to both questions, Best, Tom Driscoll On 07/26/11, Joseph Garrett<joegarrett at earthlink.net> wrote: Anyone have an idea the difference of expansion rates of Steel and Brass. I'm into a Chickering Grand and am planning on trying to anneal them puppies. Reason for asking is wether to remove the screws and drop screws or leave them in during the annealing process. Any one have some thoughts? Regards, Joe Joe Garrett, R.P.T. Captain of the Tool Police Squares R I -------------- next part -------------- An HTML attachment was scrubbed...
