Zbass Posted December 3, 2008 Report Share Posted December 3, 2008 What type of resin are you talking about. There have been a lot of threads lately talking about this. Do a search for 2pc molds and you should have enough info to answer your questions. Happy hunting. Quote Link to comment Share on other sites More sharing options...

nova Posted December 3, 2008 Report Share Posted December 3, 2008 The one thing about resin for a 2 piece is that it may warp with the heat it absorbs from pouring the plastic into it. You are better off making the 2 piece from POP. I can't speak to water putty because I can't get it here; but I assume it will work. www.novalures.com Quote Link to comment Share on other sites More sharing options...
GB GONE Posted December 4, 2008 Report Share Posted December 4, 2008 I am experimenting right now bluefish. I, like you and many others, am looking for a good alternative to the cost of aluminum but maybe a step up from pop or water putty. I have a dentist friend that is going to give me some dental impression mold material. That stuff is rock solid when dried. I have priced it and it is expensive but nowhere near aluminum. I will advise after I get the material and how it is to work with it. I am also looking into acrylic molding such as the 2 piece from Jann's Netcraft. To your original question, I have made a couple 2 piece molds from Bondo resin. Warping is an issue as Nil stated. Clamps work but are a pain and don't really resolve the warping. I also had issues with the mold halves fusing after several pours from the heat of the plastic. If the mold was for a single bait such as a swim bait, I believe it would work with no issue. If you are trying to make several 2 piece molds for production, I think you will get into a hit or miss situation. Jim Quote Link to comment Share on other sites More sharing options...
