I also used a plaster of paris mold that was baked to remove moisture. I believe that I used clay to mold the plaster of paris. I melted the lead on my stove in an old cat food can.
Be sure that most of your weight is far from the hinge line so you can get the aileron using as little weight as possible. Mine were basically tear drop shaped with just enough lead on the front half to attach securely to the arm. I think I used two steel T nuts in the lead to secure to the arm.

I heated the mold in the oven to prevent steam explosions prior to pouring the liquified lead into the mold. Once the mold was heated to 450 degrees I poured the melted lead (using proper face shield, gloves, and full body heavy clothing to cover all exposed skin surfaces) into the mold and let cool. I then shaved the lead weights using a sure file to get the weight to the exact amount needed to counter the aileron and perfectly balance it. Be very careful when pouring molten lead into plaster molds that the mold has been sufficiently heated so that all water is gone or it WILL EXPODE in your face throwing molten lead in all directions ! Another alternative is to use heavy paper/cardboard to form a square mold to pour the molten lead into, the sides can be taped together using ordinary masking tape, several layers, without the tape burning through until the lead solidifies. I have used both types of molds.
