just for the books , when i was working overseas i saw a guy making sinkers using sand and molasses as a mold , he mixed the molasses with the sand till it stuck together but wasn't really sticky to touch , pushed the sinkers ( pyramid type) into the mold point first then hung the swivels on a wire leave them half in half out of sinker , he them filled up mold with lead ,,waited a few minutes pulled wire holding swivels and the sinkers came with it , i watched him make about a 100 in a hr this way , his mold held about 20 at a time ,, oh and he had it about 6 inches deep and about 2 inches between sinkers , and was careful not to drag sinkers on sand
