This I think = will solve the problem</FONT></DIV> <DIV><FONT face=Arial>I need help to:</FONT></DIV> <DIV><FONT face=Arial>1 - Calculate the correct bore angle of the bass = hammers heads. I think that may be the same angle to all bass hammers head. The = angle from the tenor to the treble is easy because I may measure the trichords = angle to each note.</FONT></DIV> <DIV><FONT face=Arial>2 - Calculate the distance from the shank center = pin to glue the new hammers in order to obtain the correct stringing point.</FONT></DIV> <DIV> </DIV> <DIV><FONT face=Arial>If possible I would like also to read sometinhg = about this all. </FONT></DIV> <DIV> </DIV> <DIV><FONT face=Arial>Thanks to all</FONT></DIV> <DIV> </DIV> <DIV><FONT face=Arial size=2>Rogerio Cunha<BR>IC Member of the = Guild<BR><A href="mailto:rogeriocunha@openlink.com.br">rogeriocunha@openlink.com.br= </A></FONT></DIV></BODY></HTML>
