Super glue is out, and while I have Torx drivers someplace I doubt any are this small.  Same with my screw/bolt extractor sets, and both are probably buried in storage someplace.  So it the drill press. I will probably go find one of my micro screw driver sets when I get around to it (one set should be in the house someplace), find a straight slot the right size and drive it in to try to get some purchase on the grub that way.  I could also go after it with the Foredom tool, or one of my Dremels and cut a slot in the grub if I get enough light and magnification to see with these old eyes.  Small detail is not part of my world anymore. The unknown is if I tightened it tight enough to strip it, it may be set in there way tight and/or locked by the coil wire.   If it wasn't a 2013 I'd probably not worry about it, but hate to loose one from that vintage as they are hard to come by now.  Even so it's dedicated to a Woodvil I don't use much, and I have way too much else that is more important to me going on to mess with it right now.
