Color Thru Plastic / Tungsten Poison Head Jig

Recommended Posts

Hey all, I'm in the process of making a mold for a new jig head concept. It's a plastic jig head fortified by tungsten powder. The mix will bear an exact weight of the leaded jig head. The neat thing about it is you can add a colorant in the plastic/tungsten mix and it will be colored thru the head.

 

I got some lead poison head jig heads from Siebert Outdoors 3/8 oz and 1/2 oz and currently they are in a rubber mold drying. I should be able to finish making the mold tomorrow and will be pouring some heads next weekend.

 

Whatchya think about the concept?

So you're melting the plastic then putting the tungsten powder into it, then pouring?

Not quite, you mix an "A" part with a "B" catalyst part like you would with epoxy, then add tungsten powder, which comes in like a fine saw dust. Pour like you would lead and let set for 5-7 min before extracting from the mold.

 

Add dye to the "A" and "B parts and you get a colored thru plastic.

 

Specific gravity on plastic is 1.1 and adding tungsten powder in a 1:1 ratio will give you the density and weight of a lead jig.

 

If you're wondering why? Lead ban on jighead less than an oz here in MA. Alternative, that's all.

I'm really intrigued, Id love to see some final product.

Sounds cool man! post up pics of the process.

If it is anything like your other stuff it will be great. Sign me up for a couple 3/8 ;) lol

Just finish pouring the second side to the mold and the first side looked really good. If all goes well, we'll be able to cast our first jighead tomorrow.

 

One good thing happened, the second side of the mold didn't take as much RTV product, so I made a mold for brake weights to my old baitcaster. I could never find the parts to it, so as I was pouring the second side, the idea came to me.

Getting the density correct is the hard part IMO. I have tried the 2 part epoxies and have made several shakey heads but getting enough tungsten powder mixed in to create a density equal to or greater than lead has been the problem. If you have this problem solved please post it because at $45 a pound tungsten powder is expensive to experiment  with.

The problems I've run into when trying this is the powder makes the resin brittle due to incomplete bonding.  If you figure it out I'm interested also.

I don't believe I paid quite that much and I know this isn't a cheaper alternative, but an alternative to comply with our laws. Plus it's just darn fun to experiment with plastics. I made lipless cranks last year using pretty muck the same process just not with tungsten powder.

 

I'll get pretty darn close with the weight on a 1:1 mix ratio, but if you think of it, going less tungsten gives you different weights. The plastic alone still has a specific gravity of 1.1, so it will still sink.

 

The problems I've run into when trying this is the powder makes the resin brittle due to incomplete bonding.  If you figure it out I'm interested also.

According to the manufacturer, you can use up to a 1:1 mix ratio and still have your plastic pour like water. Any more tungsten, then it's like pancake batter.

I have made crankbaits before using the process you are describing. The ones above I used a 1 to 0.8 ratio for the micro balloons so they would float. The orange bait has dye that was added to the mixing process so it is solid orange. I am good at building these but my painting skills are horrible.

Came out great! I with you when it comes to painting...LOL...I made a 2 piece lipless crank mold and cranks last year as my first project with plastic. I gave MCS one and he went out and caught 2 bass on 1 cast. I thought about making jigs and adding colorants this time around, just waiting on some hooks to come in so I can start making them.

Here's the lipless crank I sent to MCS last season:

As you can see my painting skills needs work, a lot of work...LMAO!

Mine are solid bodies and I doubt if they can be broken. For a scientific experiment on durability I ran one over with my full size Yukon and it survived.

Interested in what you learned and any other pics you are willing to post. I was going to try and make some of these this weekend but my part B of the resin is no longer good.

I'm really interested in your process. Out here in Calif. the same thing is going to happen as far as the lead ban. I make jigs for guys out here and would be very interested in talking to you. Thanks Bruce, Paradise tackle.
