What should i use for a mold for lead pouring, i cant see how buying the molds is worthwhile if i could make them my self.
i picked up some sinker molds and now i want to make diamond jigs and hopkins but i dont know the best way because all of the molds available are not the sizes i use

Pretty easy to make one out of bondo. Husky did a how to on that a few years back. Should be able to find that in a search.

Alumilite platinum cure mold putty. Kinda pricey but looks versatile and easy to work with. Dahlberg (The Hunt for Big Fish) has an episode in which he works with both lead and casting resin using the putty as molds.

I use rtv silicone rubber, it's a two par liquid that will harden like rubber and can be used to pour lead. That aluminilite mold puddy should work great too. Here's some molds and jigs i have made.

I pour lead. Those molds you made really seem neat. I find that to get a good pour my mold needs to be hot. I usually pour lead on the outside of the mold a few times and then do a few without the inserts to get hot enough. Do you do anything to those to heat them up before you start?

I have been doing a lot of molding and the best way so far has been to make a box out of plexiglass and hot glue a little larger than your lure. Then put some clay in the bottom of your box. You then want to push your lure your copying half way into your clay, you want to smooth out the clay around your lure then push a pencil eraser into the clay to make alignment pins so your mold will line up later. After that you want to spray a release over everything and then mix up your rtv and pour it over the lure. For lead i have been using 70-60 tin-sil rtv rtv silicone mold rubber. After that sets you remove the clay and can pour the other side. I cut the pour spouts in after it cures.
This also works great for coping plugs, you can pour them out of casting resin mixed with micro ballon to change the density. Here's a some plug i have made.

I haven't been heating the molds. i actually let them cool between pours so the molds don't over heat. With some of my molds i get perfect pours and some i get some pitted rough finish. It seems like if your mold has a pour spout that lets you pour the jig fast it will get a better pour. also i get better pours when the lead is not too hot.

Thanks, thats good information. I have even used wood molds but for me the best for production speed are the aluminum molds.
