I want to make jigs like the ones I attached.
I know that this may seem very simple to many of you, but I have NEVER dealt with mold making, or even mixing epoxy or anything like that in the past.
If you look at the jig, it has a wire going through it. Also has multiple hooks at the bottom. I do not need to cast these.
All i really need is to cast the BODY, not the wire, not the hooks.
Now here are my few questions:
1) What product can I use to cast this mold? I have seen a youtube video of someone using RTV silicone. I liked that it was malleable. I figured I could poor my plastic/epoxy inside the mold and work it out?
2) What kind of clear plastic/epoxy can I use to make this type of jig? I was thinking the kind of epoxy you would poor on top of a bar to keep it waterproof, but do you have a clear plastic that would work better?
3) The clear epoxy plastic must be able to withstand some drilling so I can make the hole in it to fit the wire.
Is the opaque colored head lead or is it plastic as well? I'm assuming lead.
Are you only trying to pour the clear body with the tube through it or the head as well? We can help with both but just trying to figure that part out.
The body is fairly simple ... you will disassemble one or take your master if you have created your own and glue the flat part down so the cone shape is pointing straight up in the air. Then take a tube ... the same diameter as the hole and stick it in the cone so it is sticking up above the tip of the cone an inch. The tube will be an insert in your mold that you will pour the clear resin around. Then when the resin cures, you pull the tube out and your hole through the middle will already be in your cast resin piece ... no drilling required. You will want to mold release it but that is all.
You can find the tubing at almost any local hobby store where they typically have a rack with different sized diameter tubing and wire. It will cost you a couple dollars but can then cut it into many pieces for multiple molds.
Back to the mold ... your tubing is sticking straight up out of your cone. Glue to the cone to a mold base and make a box around it. I would use a cross section piece of conduit or pvc pipe or perhaps a plastic container like a recycled yogurt container that is approximately 3/8-1/2" around the lure. Seal the bottom with hot melt or clay so the rubber doesn't leak out and pour the mold using High Strength 2. Pour it all the way to the top of the tube approximately 1" above the tip of the cone. Allow the silicone to cure and you are ready to start casting.
I'd recommend the Amazing Clear Cast for your resin of choice to cast clear lures. If you are looking for opaque, use Alumilite's RC-3 (Alumires) as it cures much more quickly ... less than 10 minutes.
