mark poulson Posted June 7, 2010 Report Share Posted June 7, 2010 I am going to pour a 12 chamber mold. The masters I used to make it weigh four oz. How much plastic do I need to make four oz. of finished lures? I know liquid is measured in volume, and I don't remember how to convert to weight. I guess I could just weigh the pyrex cup and add 4 oz. of plastic, but that would be too easy. Quote Link to comment Share on other sites More sharing options...

mark poulson Posted June 8, 2010 Author Report Share Posted June 8, 2010 I wound up putting the pyrex cup on the scale empty, zeroing it out, and adding 4oz. of plastic. Then I added my salt and flake, another oz., and it worked out perfectly. Quote Link to comment Share on other sites More sharing options...

LOL What did you make your masters out of? Quote Link to comment Share on other sites More sharing options...
mark poulson Posted June 8, 2010 Author Report Share Posted June 8, 2010 I used Ika bodies with the skirts cut off. Half of the two piece mold is POP, and the other half is 20 Smooth Set drywall mud, because that is what I had. After I cured the molds in the oven at 170 for half an hour, I coated them with yellow carpenter's glue, cut 50/50 with water. I brushed it on on softly, and tipped the molds up to drain out the excess. I poured the next day, and the baits came out great. Thanks to all of you who helped me learn everything I know about pouring, and mold making. Quote Link to comment Share on other sites More sharing options...

mark poulson Posted June 9, 2010 Author Report Share Posted June 9, 2010 I would if I knew how. There's something about me and posting pictures here that just doesn't seem to want to work. I'll ask my youngest to help. She's 15, and knows everything. Quote Link to comment Share on other sites More sharing options...
