Building a JIG

Recommended Posts

Good Guys,

Present myself! I Valarini Bruno, I live in Brazil tucunares fish and other sport fish that are here in my region, with little experience I have BLACK BASS

In this tutorial I will show how to produce my Jigs quickly and easily.

Here I will show you a way to choose the format and weight of the bait.

For manufacturing we will need the following materials:

- Nails

- A piece of wood

- Wood

- Sierra Iron

- Pliers and Cutting Nozzle

- Stainless steel wire

- Mass of shape (found in paper)

- 1 kg of quick drying plaster (Found at Home of ink)

- 1 bowl for the preparation of plaster - spatula

- 1 container for preparing the mold

- Brush

- Petroleum jelly or cooking oil

- Lead

- Panel Old lead to melting of

- Source of heat (cooker)

- File and Lixa Iron

- PC-format plastic funnel

- Fita crepe

Hands to work.

Let's start with the manufacture of the internal structure of the bait, the template will do that after numerous baits can produce the same model without difficulty.

For this we choose the size of bait that will produce and hit two nails on the wood so that the space limit.




After the placement of the nails will do the first internal structure using the wire for the manufacture of python.

After python now we cut the head of the nail to make it easier to remove the wire and to use their heads in the manufacture of such




After cutting the head of the nail, save, because we will use in the manufacture of the mold as I said.

Having made the first python, we use to produce the first model of the external part of the bait, so we use the mass model.

To help make the following, take a piece of the mass and make a cylinder is attached to wire.

From now goes according to the creativity of each and taking care that the wire is always in the center of the bait.

*** TIP: Do not take the bait very large, because with it you'll achieve much weight. How do we shape in plaster, you may also be doing small grooves eyes, and any details on bait modeled. ***






After molding, the test gauge to verify that there was no change during the modeling of the bait.


Now we will go to the most critical of the manufacture of the bait, the production of the mold in plaster.


Take the container for the manufacture of the mold with a brush pass the cooking oil or Vaseline to make it easier to release the order when completed.

Prepare the plaster so it is not too watery and not too dry, according to the level of detail that the modeling of the bait was made, it is necessary for the preparation of gypsum is more watery.

Play at the bottom of the bowl plaster


Then put the bait on the plaster, so it is within 50% of gypsum and 50% out of plaster, taking great care so that python does not sink into the plaster.




*** TIP: If you play the bait and sink it in plaster, with the pick-nosed pliers and take in running water to be clean, and wait several seconds for the plaster is thick, thus facilitating alignment of bait in plaster .

At this point I added a plastic piece that will be retained and subsequently facilitate the injection of lead.

With the head of the gauge nails cut, pass oil or Vaseline to the brush and how cool it is just the bait and, as picture below:



After this procedure we have to wait for around for 15 to 20 minutes for the drying of the "A" of the mold.

The expected minimum time of drying of the plaster, remove the heads of the nails so the "A" there is not joined to the mold.

Once removed put back in place, this will be done so at the time of separation from such "A" to "B" does not damage the joint.





Now let's make the "B" of the mold, use a brush to spread the cooking oil on the "A" in a uniform manner, unless the two parts will merge.


We will prepare a further part plaster mold and place on the "A" thus forming the mold "B".





How can check the plaster when played in the bowl is isolated, to stop a flat gently tap the bowl.

Now we wait for about 1 hour.

After this time we will remove the mold from the pot, and we have something like this:


Come to the step of separating the two halves,

Be very careful, because the gypsum is a material very easy to break.

Try to pull the two parties to the contrary, be noted that the mold with the appearance of having cast side "A" and "B" you can use a spatula to remove excess plaster from the side of the mold to find the division of shares .

Now that divided the way we remove the bait and plastic piece used to make the injection of lead.


After that you will use a spatula to remove the plaster that blocks the entrance to the mold as the picture below:


Do it now several climbing irons, with the aid of gauges.




When you make a python, check this setting in so easily, if not set to quit easily. This also will help you release the bait when the injected lead.



If you notice in the photo above, you see the inside of the mold the wire in the center.

Now for the most dangerous part of the manufacture of Isca, the melting of lead.

Before starting to melt the lead you have to pay attention to the following information below:

- The plaster mold after 1 hour is very hard, that does not mean that he is 100% healed, which in time will complicate the injection of lead, because the water will evaporate on contact with the molten material forming steam, which will damage the injection. Leave the mold in a dry place for about 2 days and preferably in the sun, because only then will we get rid of water. I saw some cases items that the staff use hair dryers and even put the mold in the oven for faster drying.

- Every time you melt lead beware, because the burns can be very painful.

- Always use pants, shirt and closed shoes.

Come down to business

The materials are:


How do I use my oven, lined with newspaper to facilitate the cleaning and if it lands the lead melted he joins my sink.

Take a python, place inside the mold and close.

Use duct tape to close the mold completely, this avoids the risk of the mold is open during the injection.


Take the pot and put the lead light the fire, leave until the lead melts.

After melted in the pot, pour into the mold cavity through the mold, be noted that this vibrating the mold and lead bubbling, yet there is a sign that water in your order. Can damage the finish of the bait.

As the lead loses heat quickly, it hardens instantly be removed from the mold.

By hardening quickly, does not show that he is cold, take care to remove in order to use the pliers for this nozzle.


Take the pot and put the lead light the fire, leave until the lead melts.

Pass the running water bait for it to cool.

If you find a good logistics, several baits may produce the same type, can be painted in various colors.

After removing the mold cooling, use a file and sandpaper to remove burrs and to finish.


This ready your bait.

Now it's just paint is ready for testing.

I wish to make clear that we must take all possible care with the lead, because it is a heavy metal and can cause infection.

When sanding the material use masks with activated charcoal filter and always keep burrs to a melting later.

A big hug and hope have been clear that the ideas expressed here.

Bruno Valarini.
