Todd S Posted February 13, 2007 Report Share Posted February 13, 2007 Made a 2 piece POP mold for a 5" cut tail worm and used skewers for my guides to put the 2 halves together. When I made my 1st pour, I have thin fins running the length of the worms from the plastic seeping out the sides. Has anyone tried using bolts, washers and nut to tighten the mold halves to stop this from happening? Is there something I can do with this mold to stop it from happening? The worms also came out real dull. I sealed them w/elmers glue like recommended on this site. Do I need to coat the cavities w/something right before I pour? Any help is appreciated. Thanks.

spungee Posted February 13, 2007 Report Share Posted February 13, 2007 The dullness that you experienced was the lack of a release agent (worm oil, Pam, etc...) If you will spray or apply the agent it will help with the shine.... The "fins" that you got was probably from the excess sealant (glue in your case).......If you get it on the outside of the cavity t will leave seams that the hot plastic will seep through causing your "fins"........ not really a problem just leaves some trimming to do after they cool..... Hope this helps....... Quote Link to comment Share on other sites More sharing options...
BBC Posted February 13, 2007 Report Share Posted February 13, 2007 Todd, Do the tails on the cut tails pour with the mold closed? I was considering making a mold for them but wasn't sure if I'd be able to get the tails to come out right. Eric Quote Link to comment Share on other sites More sharing options...
Todd S Posted February 14, 2007 Author Report Share Posted February 14, 2007 No, I poured the tail in the open half then closed it up. Todd Quote Link to comment Share on other sites More sharing options...
tad Posted February 16, 2007 Report Share Posted February 16, 2007 I've started drilling 2 recesses in my first half of my pop molds, after they firm up a bit. I drill the resses with a screw recessing bit or a router bit of similar shape. This works great for producing alignment holes. I use spring hand clamps to hold the 2 halves together when I pour. I hope this info is of some help. Any questions, just ask and I'll help if I can......tad Quote Link to comment Share on other sites More sharing options...
Party Crasher Posted February 16, 2007 Report Share Posted February 16, 2007 I just use a counter-sink bit in two or three places on the first half of the mold. Quote Link to comment Share on other sites More sharing options...
tad Posted February 16, 2007 Report Share Posted February 16, 2007 Yea counter-sink is the word I should have used. I also use a router bit of the same shape and they both work great. Quote Link to comment Share on other sites More sharing options...
Fish_N_Fool Posted February 17, 2007 Report Share Posted February 17, 2007 todd pouring the tails with the mold open is probably why your getting the casting flash. That will hold the mold apart just enough fo cause that. Try pouring it closed and see if the will fill. If you still get flashing is if probably because of how you sealed the mold. You must use extreme care to not get any sealer on the part of the mold that fits together as any thing will hold the mold apart enough to get some flashing.

tad Posted February 17, 2007 Report Share Posted February 17, 2007 Using nuts and bolts will be time consuming and you run the risk of over tightening and braking your mold. Quote Link to comment Share on other sites More sharing options...
nova Posted February 17, 2007 Report Share Posted February 17, 2007 Just use large hand spring clamps. Easy on and easy off. www.novalures.com Quote Link to comment Share on other sites More sharing options...
Todd S Posted February 20, 2007 Author Report Share Posted February 20, 2007 Thanks for all the comments guys. When I sealed the mold, I sealed the entire mold which I now understand what some of my problem might be. This was my 1st POP mold so I will chalk it up to a lesson learned. I used the glue and water trick as described in one of the threads but the lures still come out dull. Did I use too much water? ie. too runny. Has anyone used poly urethane? Thanks again.

Party Crasher Posted February 20, 2007 Report Share Posted February 20, 2007 What ever you use (I use thinned Devcon) it's going to take several coats to get that shiny glazed look. It takes me at least three coats. But then stop, or you will start to loose your details. Quote Link to comment Share on other sites More sharing options...
