Naro,<br><br>Yeah, that was my idea as well. Maybe one of the more machinist-ically inclined (Tom! You listening? ) can fabricate a bit that will work non-destructively, and we'll all share it As I said, I bought a rather expensive security screw-driver set (which, fortunately, I have other uses for), but none of them works. The head appears at first glace to be a security torx, but isn't. A Torx has 6 splines, the Leatherman screwhead has 5, and the post which makes it a security bit. <br><br>I also considered drilling them and then applying a screw extractor, but I can't find an extractor that small. Arrrggghhh!!<br><br><br>Take care,<br>Andy
