Theflyingplatypus Posted August 15, 2007 Report Share Posted August 15, 2007 Plaster works very well. You just have to coat the cavity with a sealer such as epoxy or some waterbased sealer. Quote Link to comment Share on other sites More sharing options...
Willy Posted August 15, 2007 Report Share Posted August 15, 2007 Yes, you will find that many of us here use plaster molds. Some guys make great looking pours with plaster. Once you pour the plaster and it dries you will need to seal it with somthing, I use some epoxy thinned with alcohol, or sometimes enamel fingernail polish, but you will find a lot of posts on here that discuss this topic. It's really east to make a one piece plaster mold, but the bait you make will have a little flat top, where there is no plaster, but they are easy to pour and a great place to start. And the fish don't care. Two piece molds area little more difficult, but will produce more complex bait with a little practice. As mentioned before, oil the cavities of the mold before you pour, even if you seal the mold, this will allow an easy release and a shinier bait. Try the search function most people use the term "pop" when talking about plaster molds. That is short for plaster of paris. So you may need to use that as a keyword. Good luck, Willy 1 Quote Link to comment Share on other sites More sharing options...
Senkosam Posted August 17, 2007 Report Share Posted August 17, 2007 Good advice Willy. Plaster is cheapest and the easiest to use for baits that don't have thin connections (ie slider worm or grub). For that, you would have to use injection or silicone, the former not easy to come by. A POP mold can be used from start to finish in about 3 hours once the gloss coat sealer dries, but as Willy said, requires thinning regardless of the sealer for best detail. Many baits are meant to have a flat side and these are perfect for POP. Some round baits will still work with a flat side, a stick being one of them. Overpouring will allow a small rounded hump to form, making the bait appear almost full-round. You can drill small shallow pits in the cavity, giving the appearance of textured bumps. Coating is still necesarry. Air bubbles in the plastic does occur depending on humidity Quote Link to comment Share on other sites More sharing options...
