Well, since I already had everything I needed to make them the first attempt gained my friend and I about $90 worth of sinkers for about an hours work.....enough for a couple of years of carp fishing. Certainly the safety concerns are not to be overlooked (my brush with lead poisoning convinced me!) but next time I will be wearing the right kind of mask. This thread is about using non-toxic materials to make sinkers because tungsten sinkers are expensive. And again, out of materials we already have or can get easily.
