Included in the 1914 Carpenter's box I purchase last year was a nice mortising/marking gauge, pictured below. On its second use, I tightened the brass thumb screw and proceeded to strip the steel nut embedded in the fence. I pulled out the brass pins and removed the brass face, the knocked out the nut, figuring I can just replace it, and maybe I can, but I noted that it is not a standard nut, but what looks like perhaps a short steel bar that was drilled and tapped. It looks like a second set of brass pins partly when through the steel to hold it in place, or keep it from rotating. I am hoping to find a nut that fits the brass screw and fits into the hole. Not sure how I'm going to get the nut into the existing hole, from the side where that the arm goes through. Has anyone done a similar repair and can offer some advice? Thanks.
