I'm looking for a small dividing head for use on a Mini-Mill. On Ebay people offer 8" or 12" heads and I don't know what that means. How are dividing heads measured? By swing, like a lathe? Or height of centerline above the table? Or what? Thanks for any help.

Roger,
8" or 12" refers to the diameter of the revolving plate - the area you place the work on.--One way to look at size: if you need a crane to move it I'd say it's too big for a mini-mill. 12" is definitely overkill. I've got an 8" and I use it on a Bridgeport; works fine for everything I've encountered so far..
