Lead/tin solder that I have would not stick to any hook that I have. My "toy" 50 amp welder won't weld soft steel, let alone something like a hook. Even if I could get everything set up to weld them shut, the spall would ruin the smooth surface of the eye, likely causing line or knot damage without some needle file work. By then, I have WAY too much time into the project. Not worth welding or soldering it myself.
