Home Made Injector

Honestly i see no reason to mold the jig heads in

For fishing, it is better to have them seperate anyway.... When it gets torn up, you only replace the body.... Plus you can quickly change colors without re-tying

I know what you're saying, but I'd rather have my jig heads either part of the lure design (fish skull), or contained within the lure itself.

 

I'm swaying more towards having the lead part of the jig head contained within the lure, I just want to figure out how to do this properly to make sure the lures swim straight and not spin like one did on a recent test with a top pour mold.

 

Some of the lures I've made are tiny like a 1" Kopyto. In order to put 1.5g of lead in the head of the body, I need the lead to be slim and long, rather than a ball that protrudes out of the plastic.

 

I need to make the mold for the jig heads before I make the mold for the plastics.

I made a injector out of a shock for a lift gate on a Tahoe. If u know someone in the automotive field have them to save u some we change them often. The piston is aluminun with a oring the bore is smooth, it is design for pressure. i bought some aluminun rod that would fit tight for the tip i put a set screw in it to keep it from coming out. I have not thought about a tip made made of a wooden dowel but that would be a lot easier it has to be tight so it don't leak air. But the only thing would be if u heat your injector like i do the wood would burn. if u keep your injector warm after u shoot u can push out all your plastic and cycle if a couple times and blow the plug out so u don't have to clean it between shots. I used one of these for two years before i bought two from lurecraft. Only reason i changed was the ease of cleaning the injector as i am using dual injector for two colors now. PS, Only one of the shocks will work as the other has a place in the bore it still may work but i did not use it don't know why it has two different shocks but u can see the line in the outside of the shock.

If you had a wooden tip, would you even need to warm the injector more than just putting it into the hot plastic for a few seconds?

Thanks Bob,

 

I did the method you mentioned with a spinner wire through the eye of the jig hook. That part worked fine.

The problem I had was that the lure spun in the water rather than swimming straight.

I think this was because the weight was positioned to the top / middle of the lure rather than directly in front or at the belly.

This was a quick test with thin lead window strip wrapped around a jig hook.

In all fairness I didn't have time to test the lure with a shop bought ball jig head, so I have no idea how the lure performs yet.

 

What I want to achieve is pouring my own jig heads with lead, then inserting them into a multi cavity two part lure mold so the  jig hooks are concealed.

Catch and release has gone one ethical step further here in the UK

Mark u maybe right i will have to try the wooden tip and see. I heat the injectors so i don't have to take a part the injector between shots. The plastic will not harden in the injector if it is warm and u can push it out. I heat mine on a hot plate and it may get it hot enough to burn. A wooden tip would be easier to form than the aluminum one. I wanted some tips machined but i bought new injectors for what it would cost me for the machine work. I had 4 mold ports cut to 5/8 and a injector rod turned a 1/2 " it was $40.00 Cub48
