The previously mentioned fixes seem to be holding up OK, but I don't think they're going to last very long. Before getting a replacement slide (and slide stop) I thought I'd go out a limb and attempt to repair (sort of) the damaged area on the old slide using this scheme:
I realize there are undoubtedly better ways to repair it, but all I've got is a drill press. I plan on guiding a 6" long drill with a jig clamped to the slide - both held in a vise, of course.
Comments/suggestions will be welcomed.
Best Regards
