squigster Posted March 6, 2009 Report Share Posted March 6, 2009 (edited) Hi Guys, I have a 2 piece, 4 cavity 5" grub mold and I am considering drilling holes in the tail end to pour the baits vs using the ones already in the top because I tend to keep overpouring the tails by hand (because the baits will not conventionally pour (tail will not fill completely) with the 2 pieces together) and the only other way is the hand injector which takes forever in between pours to clean out and is somewhat dangerous. Has anyone done this with success? I just want to try and make sure I dont ruin the mold. Any comments would be appreciated.

96dak Posted March 6, 2009 Report Share Posted March 6, 2009 ive never poured one like that yet, but instead of drilling a hole in the bottom, why dont you just take a dremmel tool and make some vents around the tail section and try just pouring from the top?

squigster Posted March 6, 2009 Author Report Share Posted March 6, 2009 ive never poured one like that yet, but instead of drilling a hole in the bottom, why dont you just take a dremmel tool and make some vents around the tail section and try just pouring from the top? I drilled 1/16" diameter vents at the tips of the tails and the plastic got further than it did prior to not having them put it still will not pour. I knew this going in but thought I could use the injector and that works, but what a pain. That thing clogs constantly and unplugging it is not fun. I feel like Ralphy on Christmas Story "You'll shoot your eye out kid" LOL I had it clogged one day and shoved a coat hanger in the end and had a little pressure on it (upside down) and it squirted all over my hands (thank the lord for gloves). I am 90% Polish so that didnt help either! LOL Quote Link to comment Share on other sites More sharing options...

Any comments would be appreciated. a curl tail grub mold will not pour by hand no matter how you try it or how many vents you put in it,plus it was never intended to be poured that way. here are a fews ways to get it to work. use a vacum as the tail is thick enough if and only if the mold is preheated. use the hand injector, they work but common sense must be used as it could be dangerous. or use the hand injector and just shoot air into the mold after you pour most of it, then top it off . again it will have to be a preheated mold in order for it to work. add'd with using the injector you should be able to shoot 6 baits with a full injector maybe 8.

Del, As I said in my first post I knew that going in that it would not work, and I said I am 90% Polish (So there goes the common sense). I dont blame the mold design I just always think I can overcome any obstacle and tweak things to work the way I want them to. Again 90% Polish. I thought about the vacuum thing and the only thing I could come up with was tapping the vents at the ends of the tails (1/2 the thickness of one side) of the tails and threading some type of fitting into the holes and attaching a small hose from each vent to a common header back to a vacuum pump. Lots of work for one and my concern was the plastic would get sucked into the fittings so that though went away. I kind of like the "blowing air" injector idea. The only thing that comes to mind is stacking small rubber o rings around the injector nozzle to create a seal against the mold because the injector by itself will not work. Any thoughts on selaing the injector against the mold? Edited March 6, 2009 by squigster Quote Link to comment Share on other sites More sharing options...

Any thoughts on selaing the injector against the mold? No I didnt mean it like that...... for the vacumm you would have to have fitting like you mentioned. you can get very small vaccum fttings that are threads I think down to 1/8" thread size, then run some hose to a main fitting. maybe a fish store would have fittings like this for there air pumps? if you use a hand injector wether air or plastic with an oring You MUST vent the very top of the mold if you dont it will blow back all over your hands. what will happen is that your are putting pressure down and when you unseat the injector the pressure will force the plastic up. one way of sealing it would be to get a rubber airtip off a air gun( they have a bevel on them) cut it so its fits on the injector nozzle not covering the tip. then just push the injector down against the rubber tip. Again if you do this MAKE SURE YOU VENT THE TOP OF EACH BAIT due to the pressure. you can do the vents with a hack saw and a small 1/16 deep cut. you won't hurt the mold and if you did just epoxy the slot back up and file it smooth.

Pitbull Baits Posted March 6, 2009 Report Share Posted March 6, 2009 Just a quick question are you pouring with a pyrex cup or a Lee's pot. Quote Link to comment Share on other sites More sharing options...
daveh Posted March 6, 2009 Report Share Posted March 6, 2009 i thought you pour the tails first then put the mold togeather then pour the rest:? Quote Link to comment Share on other sites More sharing options...
squigster Posted March 6, 2009 Author Report Share Posted March 6, 2009 I pour with a presto pot or by hand with an aluminum cup. I tried pouring the tails by hand but I accidentally overfill them sometime plus it's time consuming. Usually I want to do at least 100 every time I pour no matter what it is and I don't want to spend half a day pouring by hand unless I am doing multiple color baits or the type of mold requires me to. I knew the mold was intended to either be poured open or with an injector I just thought pouring the tail first would work and it may. I think if I drill it out in the right part of the tail it will work as long as it's vented correctly. I may try the vacuum deal too.

Pitbull Baits Posted March 6, 2009 Report Share Posted March 6, 2009 (edited) You should try pouring with the pot. You could pour your tails first. Then pour the rest in by hand when you get the mold back together. I use a Lee's pot and I rarely over pour. I think you have more control of the plastic with the pot.

Predator Bass Baits Posted March 10, 2009 Report Share Posted March 10, 2009 What kind of injector do you have ? I use to inject my grub molds, I have 3 molds that did 4 baits each and a stainless injector. I would inject all molds and then pull the plunger out of the injector before it cooled, then open my molds put them back together then cleaned the injector and it only took 30 secs or so to clean the injector. My molds are custom made an my injector tip fits snug in the hole. I am looking to sell my setup or might make someone a deal to take them and use them.
