In another thread Jared asked how to make them so I thought I'd share ways that I have made them.
The first thing you need is wire or a wire harness. I did not know where to get anything so I used what I had on hand (electric fencing wire). As a farm owner I have lots of it around. I cut some into strips and fashioned a harness with 5 wires. I took some 2 part epoxy putty and made a head. I had the rest of the components (beads, spacers, snap swivels, clevises, and blades) on hand.
I don't have any of the originals left so I can't show pics.
A couple of years later I found a rubber mold and bought it. My friends and I made so many of the that we wore the mold out. My MacGyver grandson made me one from silicone and corn starch which I am still using.
I found a company close to me that made wire harnesses so I bought some from them. They later sold out to Lure Parts on Line who told me that a minimum order would be 1000. I am not interested.
I have use casting resin, epoxy, and Bondo fiberglass resin to make the heads. I now only use the Bondo as it cures quickly.
Here are a few unfinished rigs. The lower one is a purchased form the the others are homemade.Linkback: http://fishinpedia.com/tackle-crafting-and-modifying/20/making-an-umbrella-rig/1712/
