   I got the back plate finished for the 3 inch chuck and I'm a bit 
disappointed at my initial testing results . I've measured .015 runout 
on a piece of 1/2 inch stock that I'm pretty sure is straight . Might be 
the jaws since the chuck body indicates about .004 near the face . These 
are the inside step jaws and the clamping surface is not very long so 
that may be part of it . I'll be installing the outside step jaws 
tomorrow and checking them - it came with 2 sets of those , one which 
matches the chuck s/n and one that doesn't . The inside step set I have 
installed do not match numbers ... aaahhh , what should I expect for a 
$10 yard sale purchase !
   Actually , it may be as simple as regrinding the mismatched jaw sets 
to match this chuck . I have a little time to play with it , got no 
"other people's projects" in the shop right now .
