I've removed most of the rust, but: The sliding jaw doesn't lock onto the bar when I tighten the clamp. It looks like The notches were very shallow/small, to begin with, and they've worn out quite a bit. I tried enlarging the grooves/notches that were on the bar with a hacksaw, but that didn't really help. Does anyone have an idea for making it lock/catch on the bar? My grandpa might have several more of these clamps, and I don't want them to go to waste! Drilling holes into the bar and adding a removable pin - no, because this steel is really hard and I'd go through 10 drill bits! How about building some type of wooden cage around it that will hold it in place? The only thing I can think of is to take it apart, and use the hardware for a homemade wooden clamp. But I think it would be easier to start from scratch... I really want to fix this clamp! The quality of old tools, throat depth of this clamp, the screw, the swiveling pad - I need these! Thanks!
