Howdy y'all, this is a problem that could affect anyone, but I figured this would be the best place to ask. I'm trying to change the buckle on a shotgun belt. The Chicago screws holding it in place have probably been there 5 years or so, but I must have really torqued on them (I hate losing screws or conchos, especially at a match!). I've tried holding different rubber things against the smooth side to try to get a purchase, but it still slips, and tried wedging something between the two leather pieces, and between the two screws, to get some prying action while turning the screw, but no joy. Is there a trick I haven't thought of? Well, I did think of squeezing a bit of oil between the leather pieces with a needle oiler to get some into the threads, but I don't think I could get that close to the threads, too tight, and don't really want to oil up the leather. The only other thing I can think of is to try to cut a slot in the smooth side with a dremel, which is something I've never done before to any screw but can try. If that is what it needs, it will be a while before I get to it.
