Here are my thoughts on it. I was thinking of building one a couple months ago, asked on here and got a couple responses. I don't think too many people build them! But I bought a couple plastic blanks and looked at howthey are weighted. Here is what I plan on doing. I will build it out of pvc. It will be cut in half, and drilled out in the upper rear section so I can add rattles. The weight needs to be very low in the lure and run from. the lip til about the hook hanger. However, I have never tried to build one, but I will eventually and that's how I will start! Rob
