Teri and I met this retired man in Lawrence that use to make jigs and weights. He is a great older gentleman that use to fish the Kaw on a regular basis and he was into the catfishing end of the sport. He showed us pictures of his Grandfather with huge catfish and said some weighed 100 lbs plus. anyway he enlighten us to a sinker that he no longer makes, he actually invented according to him, ( I believe him) at any rate he told how this would work for river fishing. He gave us the mold he had made so we are going to try them out this year, We ll let you know how they work . This is the spider weight according to him.We made some trial specimans tonight, they look pretty interesting.We are going to bring the mold to the Kansas Pour. so far we have been cutting 5 pieces of solid copper wire 2.5 inches long. We have some copper wire but if you would like to make some sinkers bring some wire with you to the pour, and use the molds they are supose to grip the bottom according to Lyle.
