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.
