That is of course possible, but I would be surprised. ><<I'm willing to >change the geometry, but my thinking (and at the customer's request) is to >keep something of the original character of the action.>> > >Which "original character" of the action? If I am correct in my supposition >than the "original" action did not feel like what you have now. Something of the way the action originally felt. My thinking is that a low leverage action with assist springs is going to feel different than a higher leverage action without assist springs. > As for Renner provided assist springs and repetitions...
