edgefinder, collet or drill chick?

Lately Ive been lazy, and when I need to do something quick on a bridgeport,
i just throw my edgefinder in my drill chuck, pick up both sides and
split it.
I used to think it had to be running true, in a collet.
I know picking up center with one is deadly in a drill chuck, but what about
picking up an edge?
Do you think it would still be accurate in a drill chuck?
I do. Never tested it though.

Should work just fine. Back when I was starting out in the trade one of the older guys took me for $20 because I thought the edge finder in a collet would pick up different then when put in a drill chuck with obvious run out.

Damn, Vinny. Your memory must be shorter than my dick. Bottlbob did a whole set of experiments and tests and posted the results: the damn things don't have to be anywhere close to true. Will find the edge to the same degree of accuracy everytime.

If run out is more than .200 total you need to use a wiggler instead.
