Steve here is a link to the whip finisher. There are more than one size. For bass jigs I use the largest one I could buy.

The wire that allows one filament of FG30 is .035 my spinnerbait wire is .040. I cut a small piece of spinnerbait wire and used scotch tape to hold it where I wanted the weedguard. I clamped the mold down solid in a vice so that the wire would indent the mold. I did this for all 4 cavities.
Now I can put 1/2" pieces of .035 wire in the slots and pour away. Thanks to fred. I don't know if pics will show up but I'll try.
Yesterday I fished with a crappie guru. I took several hundred baits and a bunch of heads. I caught 3 fish on my stuff while he caught lots.
I finally begged some heads and baits. We wound up with over 150 crappie.
I have modified my mold to take the small hook #4 and weedguard (one fiber from an FG30. There is no way I can heat it up and powder paint it (he does).
I have spent all morining using finger nail polish on the heads (3 coats). Any of you old boys got a solution.
Don't even think about pouring and drilling that small of a hole.
I have had success putting duct tape over the weedguard area on both sides of the mold. I lay the wire on it and pour. I get no flash and the duct tape never even looks like it is going to melt. It's a 2 minute install and a 10 second uninstall.
Like smalljaw suggested 90# braided stainless vinyl coated leader. I use it all the time for weedguard. I never use it doubled though. I get it from BPS in 30' lenghts for $4.99 each. The ship it in from one of their stores that has salt water stuff and I pick it up with no shipping fees. I just got 2 spools this week.
If you are still having trouble after following Cadman's advice, light a candle and hold the mold over it so it gets all smoky. I don't like to do that, but I have 2 molds that won't work well any other way.
If you try to pull them apart you will get one bait made every 37 days.
I cut my rubber to the length I want + 1/2 inch. I normally use 1 tab of the base color and 1/2 tabs of what ever else I want. I put them on the jighead and wire them in place. Then I pull them out and cut off 1/4" of each section.
Yep I have the 3 stage pliers from Barlows. I can make anything I want with stainless or galvanized wire. I make jig screw locks and even tube screwlocks.
