TL;DR: For a square taper shank, do you put the edges in the groove in the middle of the alligator jaws or just the flat-to-flat (ignore the grooves in the middle of the jaws)?
This is a stupid question but I'm honestly stumped because it seems not to be working either way in either brace. I bought one of those shiny, new TFWW square taper drill bits thinking to use them in my LV yellow/black brace or in my father in law's old stanley...
but they seem to be wildly off center from the centerline of the sweep in both braces. I'm pretty sure I'm doing it wrong, (will try to post photos tonight). disclaimer, I'm usually a diehard screw gun kinda fan, so this is new to me. I have most of the neander books, but this seems so basic no one bothered writing it down.
