redg8r Posted June 22, 2004 Report Share Posted June 22, 2004 Id recommend not using any pourable plastics or foams in your aluminum molds. Reason is, most are urethanes & one slip or incorrect use of a release agent & your mold is toast. You probably know using any plastic as a jighead will reduce its weight. might be a good thing though. believe it or not, polymer clay might work well for this application. its not a good product for making larger baits because its brittle but for a typical jighead it might work well. It isnt really a clay, its a PVC plastic that has the consistency of clay, it cures in an oven @275 degrees for @15 minutes Just put the clay in the mold, compress it using the handles of the do-it mold, remove along with the hook & bake in your oven..... worth a shot. your local craft & hooby stores carry the clay, brand names are Fimo, Sculpey, Super Sculpey, Sculpy II & III. The only other thing I can think of is to use an epoxy putty like 2-part plumbers putty, use the mold to form the jighead around the hook, but be sure to use a mold release & remove the putty before it cures to prevent it from sticking to the mold. let us know if you try it.

Art Brush Posted June 22, 2004 Report Share Posted June 22, 2004 Jighead, I've tried using the 2 part plumbers putty or epoxy putty in 2 part plaster molds with vaseline for a release agent. Works like a charm. The polymere I found to be way too brittle. Tight lines, Shawn Quote Link to comment Share on other sites More sharing options...
dlaery Posted June 22, 2004 Report Share Posted June 22, 2004 http://www.tekcast.com/casting4.htm Here is some stuff I have seen used in rubber silicone molds. It is in a liquid form, about like thin syrup, mix the Part A and Part B, pour in mold, and it sets in a few minutes. The parts we did were just a hard plastic parts. You could bend the parts a little, and were very hard to break, almost impossible. You could call this company to see how it would react to alum. molds. This was used in a spin casting machine but they said it would work in a gravity mold. Quote Link to comment Share on other sites More sharing options...
cheesehead Posted June 23, 2004 Report Share Posted June 23, 2004 Sounds like this could be used to cast hard body crank baits as well. I wonder how this would work in a mold made from water putty. If I ever get to the bottomof my honeydo list I might have to give it a try. I'm thinking if you can put alluminum in it why couldn't you use lead to make it sink faster or even place stryrofoam beads on a wire to make it float?
