I'm not sure I get it, where does the extra plate tension come from with bushings? I can imagine a little pressure at the webbing but over all the same tension at pitch. Are we talking about the different position of the tension, some at the holes versus the flange? Doesn't the fact that there are screws through the plate into the top of the pinblock transfering some tension in the same direction as pins riding holes or bushings negate that idea? Could comeone please enlighten me?<BR>
