I really think Jim meant that 6 is the magic number indicating that an entire set needs to be replaced. Excerpt from Jim Harvey's post in the archives: <pre>* Harvey's "Rule of Six" - if six or more of anything is broken (elbows, strings, hammers, et al), it qualifies as a set. Client has two options, authorize the work or not. * You will not be able to tune the piano without breaking more 'bows, unless you have practice NO settling blow. Even then I've seen some -- make that many...</pre> Joseph Garrett wrote: <blockquote type="cite" cite="mid001d01c44b5b$947acf00$2a2079a5@z0w5j1"> <pre wrap="">Patrick, I knew I heard that somewhere before.
