   In the new Mongolian 6-jaw I cleaned up the scroll plate fit quite   
   closely on its pivot in the body, too tight until it was cleaned. I   
   don't think it could shift away from whichever pinion I tightened.   
   Perhaps it might in a worn chuck.   
   ------------------   
      
      I don't think this chuck has much wear . All the jaws look "new" but   
   that doesn't always mean much . I was told the original owner was into   
   woodworking , which doesn't necessarily require the precision needed for   
   metal working . By tightening all 3 pinions I have gotten it down to   
   average .004" , which is pretty close to my original equipment 5" chuck   
   . I can live with that ...
