I have also noticed the = different technique needed to set the string during fine tuning. Firm test blows = usually have no effect, I have to make more micro moves with my hammer to place = the tension properly, in the tenor and I was wondering if the material under = the felt would fail causing it to cut a channel making it = contact more of the understring felt. I like your idea of the brass half round = with thick understring felts and I'll experiment with this if time permits. </FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>I'm starting to do more with major repairs and refurbishing of original components and I frequently check the archives = of this list to see what alternatives others have used sucessful or not.
