Also, when I tried a new pin (4/0) in a hole with no "black" in it, it was jumpy too and did seem too tight (torque 160).  I tried tuning pin driving fluid (APSCO) in a couple of the holes.  At first it seemed to do the job and eliminate the jumping, but a couple of hours later they were almost as jumpy as the others. Any ideas would ! be appreciated!</font><font face="arial"> </blockquote><br> Did you ream the holes and/or use a gun barrel brush to deglaze them?<br> <br> Dipping the pin into powdered rosin before driving them in helps to improve the feel.</font><br> <div>Regards,</div> <br> <div>Jon Page,   piano technician</div> <div>Harwich Port, Cape Cod, Mass.</div> <div><a href="mailto:jonpage@attbi.com"= EUDORA=AUTOURL>mailto:jonpage@attbi.com</a></div> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ </html>
