Husky Posted May 27, 2010 Report Share Posted May 27, 2010 (edited) I made some swimbait molds from a model of my own design. The first few are made from slicone using the squish method. I had some POP/Durhams around so, I made a mold using the same model. When I looked at the pours. side by side, the POP pourings were noticeably. larger, appx 1/4 inch longer and proportionally wider, on a 3" casting, BUT the pours are totally symetrical, not stretched or in anyway compromised. They are just larger. Actually, I'm OK with it as now I have 2 sizes but I'm a bit miffed how this could have occurred. After comparing further, The POP pours are the same size as the original model (A hard urethane model, ) with the Silicone pours being smaller. "Curiouser and Curiouser." I don't have a comparison shot of the pours side by side yet, but here are some pics of the Silicone mold and pour which were the ones not following the models dimensions.

Pitbull Baits Posted May 27, 2010 Report Share Posted May 27, 2010 Pop is made for casting and making molds. Silicone isn't the cavity in the mold must of shrank a little. Quote Link to comment Share on other sites More sharing options...
Husky Posted May 27, 2010 Author Report Share Posted May 27, 2010 Pop is made for casting and making molds. Silicone isn't the cavity in the mold must of shrank a little. I used the water cured silicone sealant. The difference in the lures is about 10%, which is a lot. Usually, I remove the models relatively quickly but I will experiment with leaving the model in the Silicone for a longer time (more than 1/2 hour) to see if that will make a difference. Don't you just hate shrinkage? Quote Link to comment Share on other sites More sharing options...

Don't you just hate shrinkage? Personally, I think it looks SHARP in both sizes. I have to agree though, I think the silicone just shrank more when it cured. Either way, it is like you said, now you have that bait in 2 sizes. Quote Link to comment Share on other sites More sharing options...
