Redfish 452

Thanks to all for the sage advice. Made a 3 cavity mold. (Will forward a pic). Shot some baits and it worked perfectly!

Bob, on the hand drawn diagram you posted, I see what you recommended as vents. What size (I.D.) should a vent be? The size of a wire coat hanger? Paper clip?

Got it Bob. Thank you very much. Gonna work on a new mold tomorrow. All you guys have been very helpful.

If it is not too much trouble, could you please explain what you mean by a side injection mold or a bottom injection mold?

By "heated injector" are you referring to an injector that has been heated or an electrified injector that heats and maintains the temp you want by itself? If so, where does one get this type injector?

Thanks for all the advice. I purchased a digital thermometer and will enlarge the injection port. Down here in LA we are under tornado watches and extremely bad rains as I type so I will have to wait till the weather clears as I am working outside under a carport.

I can easily plug the gate vent and give it a shot. No pun intended. Someone suggested keeping the injector pressured a little longer. How long? Minutes?

Sorry this took so long. I had to figure out how to send a pic.

Yes, I would certainly be willing to make a new mold. In fact, my goal was to eventually make a multi cavity mold.

Thank you very much for your input. The dents are major in respect to the position. They are in the forward position of the bait body and make it hard to insert the jig head in that the body is no longer full in the location where the keeper portion of the jig head falls. I will try to send a pic of the mold halves. Also, FYI, the mold is made out of a fairly hard RTV material. I am sure this makes somewhat of a difference in curing time as opposed to a milled aluminum mold.

Regarding the sprue? Is that where you insert the tip of the injector? If so, I made it to fit the injector tip which is about 5/8 inch.

Thank you. Will get one.

Any suggestions on the best type of thermometers? Infrared?

Thanks for the advice, I will try again tomorrow.

I am new to the forum and have greatly benefitted so far by reading, reading, reading.......... I have been pouring my own swim baits in one piece (open top molds). I recently made a 2 piece injection mold and have had limited success so far. I inject the plastic and upon removing the bait, I find a slight depression in the side of the bait, The depression is not due to a bubble ( it has no sharp edges like a bubble) but looks as if the side of the bait just sunk inward after cooling. has anyone seen this problem before? Any suggestions?
