Where to put vent channel

Recommended Posts

I’m using the poison tail mold to make bladed jigs using Figure 8 link.  Using a big hook and the link I have a lot of issues getting the collar to pour.  It has to be a perfect pour right down the hole for the collar to fill.  Was thinking of maybe doing a mod and putting a vent channel to help it?  Was thinking best place would be at the bottom of the collar area where the hook exits the jig.  But since I’ve never done this looking for advice since I’m not sure of the liquid dynamics which are happening in the mold.  Or would opening the pour hole be better?  Thanks in advance.

The main problem is the cool hardware blocking and solidifying the lead too quickly.

Lay hook and figure 8 link in mold.

Heat hook, figure 8 link and collar area with a propane torch. (quick blast)

Close mold, pour jig. Your percentages are going to be a lot higher after heating your hardware.

Give it a try. Good luck.

All of the above help, but the mold was not designed to have 2 hook eyes blocking the lead flow to the collar area.

Heat is your friend.

Dink, where do you get your chatterbait blades?

Thanks for the tips.  I do all of those things.  I added the vent channel and it helped a lot for the 3/8 oz head but the 1/2 still needs a perfect pour even with heating the components.  Really seemed to need the lead nozzle all the way down into the pour hole too.  Vent helped some but didn’t solve it for the 1/2 oz head.

A Ladle (Apdriver) and more Heat.

I prefer to make my Bladed Jigs with the Poison Swingtail Mold and a home made Wire Form.

You do have to tie a Bait Keeper using this mold, but it has one less collar that needs to fill.

Also it has no weed guard hole, so the top looks a lot better.

Happy accident.

I am using a Lee lead pot that was used when I got it.  I cleaned out the pot, and the plunger, but it still poured slowly.  So i drilled out the spout hole with a slightly larger bit, and now it pours like a ladle, but with more control.  I also sprayed the pot insides with Arsenals Dropout.

I live in warm sunny SoCal, but I still heat the hook and collar area on 90% of the jigs I pour.

Air trapped in molds will only give you a minute incomplete fill.

If you are heating your hardware and still getting bad pours it's a lead flow problem.

Clean your spout. Wear gloves and ream out the spout with a piece of wire. (spinnerbait wire form)

Be careful!

Also placing the lead nozzle all the way down into the pour hole can prevent air escaping from the top.

Gravity is your friend. I like the nozzle about 1/4" above the mold. Everyone has there own way of doing things.

So do it anyway you want, I am just trying to help. Good Luck.
