I really want to start with a pompano jig mold.any help would be great.

Pat here's how I do it, but I'm sure there's more than one way to skin a cat.

The first thing is find something to cast the mold into. In this case I used about 3 inches of the bottom of a quart plastic cup, I slit the cup down one side half way down the cup. This is for the hook.

Spray the jig your going to mold with WD40. Mix up enough Bondo to fill half the cup and pour it in the cup. I usually cut 10 penny nails in half and set two of them into the Bondo for alignment dowels. Now carefully lower the jig halfway into the bondo. It will basically look like this at this point.

I just hold the hook to keep the jig from sinking into the bondo as it sets fairly quick.
Now after the bondo is completely set hard you can spray everything with
WD40 and pour more bondo on to fill up the cup.....but......I usually pop the jig out and file/sand the mold flat. Then I put the jig back into the mold and fill up the cup with bondo. It will basically look like this.

Once the bondo has set hard, pop the mold out of the cup and very carefully seperate the two halves, you can use a putty knife but be careful. I then take a dremel and hollow out a pouring spout.

Personally for a pompano jig I'd buy an aluminum mold close to what I wanted then modify it with a dremel.

By the way everyone of these things are risky at best. I beat them on the workbench to try and get any air bubbles out while the bondo cures. These big jig molds really get hot with 4 ounces of lead in it.

Obie, I have been using plaster of paris to make my molds but it breaks apart way to easily when getting the jig out, just wondering if you have the same problem with bondo?

Jigslinger · Posted: Sun Mar 16, 2008 9:50 pm Post subject:

Bondo works like a charm. I made three of them and I haven't had any problems.

is there one certain type to get?

Jigslinger · Posted: Sun Mar 16, 2008 11:55 pm Post subject:

Just regular bondo is what I used. Make sure the first half is completely cool before you do the second half and don't be stingy with the WD-40. Like Obie described, before setting the jig in place, try to get as much of the air out after pouring the first layer by banging it on the table. This also helps to level it out. You should be able to see a few bubbles work their way to the top. I popped some of them with a toothpick. Good luck.

Jace for best results wait for the first pour to set and come back to room temperature.

lesson learned when you put wd-40 on put what you think is enough then put a whole lot more.

Jace, try using a knife blade to pry it apart, but be careful.
