      Further testing having been completed the chuck has runout with all 3   
   sets of jaws of around .007" . Chuck body is more like .002-.003 . A   
   known straight 1/2" rod is not pointing  straight with the ways ...   
   looks like it's time to set up the toolpost grinder .   
      So it looks like maybe a cheap chuck , though well made . Fit and   
   finish are good , everything fits as it should and the scroll moves   
   smoothly with all 3 pinions . Which brings me to a question - since   
   there's more than one pinion is it going to make any difference which   
   one I use ? Do I need to give 'em all 3 a twist when I mount a piece of   
   stock ?

   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.
