Subject: Lead aileron castings
To whom it may concern;
I calculated the size/weight needed then made a mold using plaster paris of
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.
Hope this is of some help
