jigmeister Posted March 16, 2006 Report Share Posted March 16, 2006 I came up with this idea a while back and puchased some silicone mold making agent and finally got around to trying it out . I had a friend with a lathe turn me down a prototype Senko type bait with no rings or segments (smooth tapered sides) and a cone shaped sprue on the end sized to fit into a piece of PVC pipe 3/4" . I put the proto-type bait master in the PVC pipe tail up and poured the silicone in . After setting up I de-molded the master from the silicone which took more than time than I anticipated . I used dish soap to lubricate the master and was finally able to pull it out of the new mold . It came out a perfect duplicate . Since it worked I am planning on making a rack to hold several of these single round molds in a row for fast pouring . Probably easier just to buy one of Dels molds for stiks but if you want a custom full round mold of your own design this works - Jigmeister Quote Link to comment Share on other sites More sharing options...
CrawChuck Posted March 16, 2006 Report Share Posted March 16, 2006 Cool idea! I was getting ready to make a nightcrawler mold and that seems to fit the bill. Do you vent the tail or just pour slow? Quote Link to comment Share on other sites More sharing options...
tactical bass Posted March 17, 2006 Report Share Posted March 17, 2006 Great idea, any pics of the turned prototype? Did you use wood, and if so did you treat it or coat it somehow before making the mold? TB Quote Link to comment Share on other sites More sharing options...
jigmeister Posted March 17, 2006 Author Report Share Posted March 17, 2006 I have the mold set up to pour with the sprue end at the top with the mold sitting verticle . as the plastic is slowly poured in the the air escapes by rising upward as it is displaced by the plastic . The first prototype I made was made of hand shaped balsa that I coated with devcon to seal after shaping . I wasn't happy with the outcome with that one so I had my buddy make the next proto out of delrin plastic since thats what he had available . I coated that one with epoxy to eliminate the machining marks Quote Link to comment Share on other sites More sharing options...
