emptystringer81 Posted March 29, 2016 Report Share Posted March 29, 2016 I have a guy sending me some plastisol molding clay and glycerin, was thinking of trying to make my own molds with pplaster of paris, but is there a certain kind I need? Also what would glycerin be used for Quote Link to comment Share on other sites More sharing options...
JRammit Posted March 30, 2016 Report Share Posted March 30, 2016 (edited) Not sure about the glycerin??... Looked it up, way down in the article under uses says "to lubricate molds".... Pam cooking spray is what most use for this http://pioneerthinking.com/crafts/what-is-glycerin The pop i use is made by Dap... Im sure any will work though.... Careful, if you thought shooting plastic was addicting, wait until you see your own creation come to life!.... Theres no going back after that Edited March 30, 2016 by JRammit Quote Link to comment Share on other sites More sharing options...
emptystringer81 Posted March 30, 2016 Author Report Share Posted March 30, 2016 I use Pam to spray in my molds also, but do you use Pam to spray on your bait or one half of the pop mold when your making it so the two halfs don't stick together? I'm wanting to paint both halfway of the mold with epoxy so the baits will come out shiney and not dull Quote Link to comment Share on other sites More sharing options...

I'm wanting to paint both halfway of the mold with epoxy so the baits will come out shiney and not dull I spray Pam all over the 1st half, then rub Vaseline around the edges Epoxy makes a right shiny bait!... You'll need at least 2 coats, the dry pop will absorb alot... I use a combination of elmers wood glue mixed with water, then epoxy on top of that Quote Link to comment Share on other sites More sharing options...

goldenshinner Posted March 31, 2016 Report Share Posted March 31, 2016 JRammit do you mix the Elmer's into water to make the mix with plaster while setting up?such that Elmer's is in the plaster..not just a coating like the epoxi..what ratio..also word on street from another hobiest was saying anything but the aluminum molds don't dissapate heat fast, and can be concern Quote Link to comment Share on other sites More sharing options...

It will shoot better and eliminate cold cracks.... But if you're shooting thousands of baits a day, yea you want aluminum Quote Link to comment Share on other sites More sharing options...
Travis Posted March 31, 2016 Report Share Posted March 31, 2016 When it comes to molds simply more is often better. Waiting for molds to cool down just wastes too much time. That is the one of good things about making molds, cheap and easy to make the quantity you need to avoid these issues. I always wanted a minimum of molds that I could pour out the 4 to 6 oz of hot plastic in one go if microwaving. If I had to stop then that meant I as having to reheat. With a presto pot set up no reheating issues but I always prefer to use it as quick as possible also to eliminate risks of color variance in the batch. 1 Quote Link to comment Share on other sites More sharing options...

And of course, the more you pour, the hotter the molds get.......and the longer your wait time. Solution?? Talk your wife into investing in more molds! lol 1 Quote Link to comment Share on other sites More sharing options...
goldenshinner Posted March 31, 2016 Report Share Posted March 31, 2016 You just plan for slow cooling with your design with anything else. One outfit I know of doesn't use aluminum molds for anything except making masters. They have huge flats of of their own in house silicone molds they open pour in. Their issue is man power and cooking time. They just kept making molds until cooling time wasn't an issue. do they poor into silcone molds or plaster? and are these one up or 40 up moldes???
