Artificial All The Way Posted March 24, 2009 Report Share Posted March 24, 2009 After reading up on you guys using resins and other materials for molds I figured it was time to give some a shot. I made one out of fiberglass resin and one out of bondo. Didn Quote Link to comment Share on other sites More sharing options...
Tman2 Posted March 24, 2009 Report Share Posted March 24, 2009 So, you didn't need to seal the mold before you poured? I wonder if you would have laid some screen or fibreglass mat in just after initial molding, (while the rein was still liquid) 1/8" to 1/4" down (from the top while poring, but the actual bottom of mold) if that would've been enough strength to resist cracking. Looks like it'll work either way. Quote Link to comment Share on other sites More sharing options...
nova Posted March 24, 2009 Report Share Posted March 24, 2009 The cracking is probably from a little too much catalyst. This will cause more heat and cure too quickly causing the resin to contract and then crack. Nova Lures Quote Link to comment Share on other sites More sharing options...

nova Posted March 24, 2009 Report Share Posted March 24, 2009 I've made them with 6" nails in between the baits to try and stop the warping. That worked; but as far as the smell transfer goes I never got around that one. www.novalures.com Quote Link to comment Share on other sites More sharing options...
Artificial All The Way Posted March 24, 2009 Author Report Share Posted March 24, 2009 Nova, you saying you sealed the resin mold and still had the smell of resin on the lures? Quote Link to comment Share on other sites More sharing options...
nova Posted March 24, 2009 Report Share Posted March 24, 2009 Nova, you saying you sealed the resin mold and still had the smell of resin on the lures? No I didn't seal the resin molds. I just set them all aside and made POP molds. I don't use them any more(haven't for years). The smell transfer will not help you catch fish. In order to seal POP the one thing that has to happen for a good finish product is that the sealer must penitrate the POP to give a good base to connect to. In the case of resin; it's going to have to be something that glues itself to the resin and that's where your limitations are going to be. Epoxy will bead and separate; waterbased products will just bead. The only thing I can think of to seal resin is going to be a special paint for fiberglass and with that you may get color transfer. Not to mention the cost for special paint. My suggestion is to go to POP and cut your costs. The end result(baits) will be the same quality as from a resin mold if it's done right. www.novalures.com Quote Link to comment Share on other sites More sharing options...
Zbass Posted March 24, 2009 Report Share Posted March 24, 2009 maybe my smeller is broke or something, but I have used resin for 4 or 5 years and have not noticed a resin smell on my baits. Once the resin is cured, I do not smell them. I don't pour hundreds at a time so the molds dont get that hot. Maybe that is what is causing the mell you refer to. As far as the hardner goes, I only ue about 2/3 or less of the ratio on the can. if you use the exact ratio you will get cracks or splits because it has too much hardner. Hope that helps Quote Link to comment Share on other sites More sharing options...
IGOTWORMS Posted March 25, 2009 Report Share Posted March 25, 2009 I fully agree with zbass on this one, I have been using resin to do all of my molds for years now. I do pour a few hundred at a time, not day in and day out. But when i am running low on a color I pour enough to last a while. I have never noticed a smell unless I did not add enough hardener to the mix. Judging by the color of your mold, you surely added too much. with resin there is a fine line between too much and not enough. beleve it or not weather can also play roll in it. One problem I think people are having with resin and smell is, just because the resin is in a ridgid state does not meen it is fully cured. Sure you can pour it after 20-30 minutes, but it is not fully cured for a few days. So people if you are having a problem with your resin molds worping or getting smell transfer take my advice into cosideration. Make your molds and let them cure for a few days... Yes I have a problem with it also:drool: Quote Link to comment Share on other sites More sharing options...
Artificial All The Way Posted March 25, 2009 Author Report Share Posted March 25, 2009 Thanks guys. Be it resin or POP what is the best thing to use to keep the frame work and master lures from sticking to the mold material? Will cooking spray harm the POP or resin?

nova Posted March 25, 2009 Report Share Posted March 25, 2009 I don't use anything for POP but for resin you can use a tupperware type plastic container. As far as the "smell" goes with resin; I can only relate my experiance with it. Now maybe it's a curing thing but I got the smell for months after it was set. It may also be the chemical comp of the resin that I used. Who knows for sure. www.novalures.com Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted March 25, 2009 Report Share Posted March 25, 2009 For my plywood pour boxes, for resin, I use a generous coating of floor tile wax, purely because I have a large tin of the stuff. I guess any type of wax will do the job. Like Nova said, PoP does not require anything, but I wax anyway (I like the smell!!). Dave Quote Link to comment Share on other sites More sharing options...
KO Joe Posted March 25, 2009 Report Share Posted March 25, 2009 There must be a difference in the resin that we are using because I have never had an odor problem from my resin molds either. Resin molds show great detail since they do not need to be sealed. If you are using a plastic lure for a master carefully shine it first with a torch on low. That will produce a shiny lure poured from your mold. Quote Link to comment Share on other sites More sharing options...
Artificial All The Way Posted March 29, 2009 Author Report Share Posted March 29, 2009 (edited) Judging by the color of your mold, you surely added too much. with resin there is a fine line between too much and not enough. I bought another brand resin and got a diff color. So the first mold is the color it should be. Both containers had the exact amount they should of had which I could see because they are marked and in see the lines. Well its been a few days and the mold is rock solid and has no more smell. I filed the edges smooth and patched the parts that chipped off. Dam near perfect just like the lures are coming out. Maybe I'll put up another post on my molds. I just made a couple resin, POP, bondommolds, and one that is half resin (what I had left after making a mold) and half bondo for my own personal test. So in the mold cavity it self half the wall up is resin and half is bondo. They meet perfectly and marry together. I did't seal the bondo or resin molds at all. They are producing perfect lures with no smell on the lures or left in the mold. I'm now going to seal a half dozen POP with diff materials to test them.
