Mac,
When you close up the jaws in the chuck without anything in them do they
close uniformly and butt against each other fairly tightly?
Do you have a regular set of #2 jaws for the chuck you can try. I have the
#1 spigot jaws for my Stronghold and I don't really like them for holding
bowl tenons. I can't say I've had the grief you seem to be experiencing
but
I prefer the regular jaws.

Bill.. at George's suggestion, I checked the spigot jaws and when
closed, one jaw is very, very slightly further forward than the other
3..
I took them off, cleaned the inner jaws, etc., and put them back on,
making sure that only the jaw with the pin was in the same position as
before.. still didn't seem even, so I took them off for now..

Went back to the #2 jaws that came with the chuck, and they seem, if
not exactly flush at the ends while closed, closer than the spigot
jaws were..

I've checked everything on the chuck and can't see what would make one
outer jaw stick out more than another, so I'm thinking that I might
need to true the ends of the other jaws with emory cloth or
something..

Mac,
My Stronghold spigot jaws are dead flat across the tops (by eyeballing when
closed). You don't say how much they are out. Do you have a instrument
capable of accurately measuring them the variation in height?
You might want to give Oneway a call but I would try to get a measurement
first since they will probably want that info. I understand they are very
helpful with any concerns about their products.
Have you measured how true the chuck body runs on the lathe? A dial
indicator is great for this.
