New shanks cost money and need a bit of fitting to the instrument, implies a hammer change in anycase. Knuckles themselves get replaced easily enough. You can pop off an old set and get a new set installed very nicely in a couple hours. If you have a set of poorly installed knuckles and hammers and shanks are otherwise reasonably ok.... In anycase i choose that over bolstering for the most part now. <BR>  <P>-- <BR>Richard Brekne <BR>RPT, N.P.T.F. <BR>UiB, Bergen, Norway <BR><A href="mailto:rbrekne@broadpark.no">mailto:rbrekne@broadpark.no</A> <BR><A href="http://home.broadpark.no/~rbrekne/ricmain.html">http://home.broadpark.no/~rbrekne/ricmain.html</A> <BR><A href="http://www.hf.uib.no/grieg/personer/cv_RB.html">http://www.hf.uib.no/grieg/personer/cv_RB.html</A> <BR>  </FONT></P></BLOCKQUOTE></BODY></HTML>
