Big Ray Posted February 16, 2015 Report Share Posted February 16, 2015 Are you asking what do you need to make a mold to make soft plastics. If you are I would use plaster of paris. I know other guys use different stuff but so far that is what I have used and it works pretty good. Quote Link to comment Share on other sites More sharing options...
Jig Man Posted February 16, 2015 Report Share Posted February 16, 2015 I use Bondo fiberglass resin when I make a mold. Quote Link to comment Share on other sites More sharing options...
Anglinarcher Posted February 17, 2015 Report Share Posted February 17, 2015 Alumilite RTV. Check out the Makelure.com site and look at the HS1, HS2, or even the HS3. Also, check out their how to videos. Quote Link to comment Share on other sites More sharing options...
aulrich Posted February 17, 2015 Report Share Posted February 17, 2015 Mold silicone is easy to use, but not cheap. And can have odd outcomes, I tried to copy a Berkley Gulp bait and the silicone did not completely cure, it does make usable bait. I don’t know about Plaster of Paris, but I ran into some Durham’s water putty (very rare here north of the border ) but is was very easy to use as well. But as with all of the hard mold materials no undercuts unless the master is soft. My first attempt turned out reasonably well. Since they set up fast bubbles can be a problem, there are ways to slow down curing and reduce the bubble issue. I will go back and buy the rest I saw it’s not as cheap as POP, but not what you would call expensive. I have not tried bondo/resin yet Quote Link to comment Share on other sites More sharing options...

Anglinarcher Posted February 18, 2015 Report Share Posted February 18, 2015 If you are using RTV, then sometimes you can have issues if the Master you are molding is of certain materials. I have not tried molding a Berkley Gulp, but it sounds like it has some sulfur in it and that is one of the cure inhibitors for the liquid RTV's. If you used mold putty then it would be fine, or ....... dip the gulp bait in a clear coat (won't last but who cares) and use that as a master.

Lonestarbaitcompany Posted February 20, 2015 Report Share Posted February 20, 2015 For detailed instructions on how to make a PoP mold you can go to the webpage in my signature. PoP is the cheapest to start with, for around 40.00 you can make a lot of mistakes and still get useable molds. Quote Link to comment Share on other sites More sharing options...
