This rolling created a "thread" on the surface of the reamer that is just a little more aggressive than the original. When I need just a little bit more looseness than the nominal dimension of the reamer gives me, I carefully insert this part of the reamer and give it 1/2 twist before drawing it straight out. regards, Ed Foote RPT http://www.uk-piano.org/edfoote/index.html www.uk-piano.org/edfoote/well_tempered_piano.html
