Shaane Posted January 12, 2009 Report Share Posted January 12, 2009 I have been reading all I can about making molds, pouring soft plastics etc. And have experimented with POP on a couple of molds. Here is what I want to try; tell me if there is an easier way please. I want to take the main body of a particular soft plastic lure and add a split tail to it (this will all be a 1 part mold to keep things simple) Pour a "rubber mold" of both the soft plastic and tail seperately, pour into that mold a harder material (pop) the rubber mold will allow me to bend and stretch the hard material out. Then I will glue the hard tail to the hard body, sand and fill imperfections and add indentations for eyes etc. Now I will have a hard master. I can then make a mold of the master and pour from there. I am comfortable with the rubber material I have been experimenting with. My question is once I begin to pour the hard molds what material is best for gluing the tail to the body, light sanding and filling any imperfections that occur from the rubber mold. Can I mix POP and use it as a filler on a dried hard mold??? Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted January 12, 2009 Report Share Posted January 12, 2009 The method looks reasonable to me. But you should find a better material instead of PoP. The chances of successfully demolding thin sections cast from PoP are very low. PoP is far too delicate when first poured and too brittle when dried. Bondo might be a better material for the cast, but I am not sure about bondo in RTV molds. Maybe someone could confirm its suitability.

nova Posted January 12, 2009 Report Share Posted January 12, 2009 As far as gluing POP; epoxy is very good and it will fill in some inperfections if they are not too large. www.novalures.com Quote Link to comment Share on other sites More sharing options...
longhorn Posted January 12, 2009 Report Share Posted January 12, 2009 This sounds like a lot of work to add a tail. What form is the existing lure and tail in...are they soft plastic or hard material? There are other options that may be easier depending on the answer.

HJS Posted January 16, 2009 Report Share Posted January 16, 2009 (edited) Shaane - I'm not entirely sure what you are trying to do. But I think I understood enough to show you what I would do to add a split tail to an existing lure. I use these modified lures for masters when making a new mold. The picture is pretty much self-explanatory. I tape the original lure on its back to the bottom of a glass baking pan. In this example I'm using a standard 5" Bass Assassin. Pour a puddle of plastic over the end of the tail. Wait a few minutes til it gets hard. Then use sissors to cut a forked tail (except do a better job than I did). And there you have your master. Make several so you can make a mold with multiple cavities. Now, you mention something about adding a "stretch" component in addition to the split tail. Not sure if the techique I describe could be modified to also stretch the lure out. You'll need to figure that out on your own.
