Lets talk runnout

[Kennyv]

now what id like to know and get someone to concur is their is a good possibility in what I have observed as far as up to .0035 runout with a good quality chuck lest say 1-2 " from spindle can be from removing taper pin ?

or that should't mean squat Bc i do get good readings with lets say 2-4" down from collet face when using collet instead of drill chuck ?
