Re: Further testing needed ...

   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.
