you increase the resistance of the pinning, <U>you must also increase the
spring tension to overcome this resistance</U> for a given hammer lift."
Of course the spring tension doesn’t get increased until you increase
it. The point is you <I><SPAN style="FONT-STYLE: italic">can</SPAN></I>
increase the tension helping to return the key and hammer without making a
jumpy hammer.<o:p></o:p></SPAN></FONT></P>
