I am trying to cast two separate pieces of aluminum for skateboard trucksand i would like to have a reusable so i could make many sets of theseI dont know how to do thisi have a lot of ordinary clay at my disposal, would a clay mold work for casting?Help?
Normal way would be to machine a 'master' of the truck them pack the master into the clayCarefully cut the clay in half, remove the master, join the clay half's back together, make a pour hole or a 'sprew', pour in the molten aluminumNow, I have no idea if this clay you have is suitable or notNext up would be to have the truck shape machined into two steel blocks, half on each sideClamp the blocks together pour in the metalBecause the melting point of steel is much higher then aluminum, the steel mold should last quite a whileAfter the aluminum has mostly cooled, remove the clamps pop-out the rough truck shapeUsing the two piece steel mold would probably be the best ideaLook-up 'mold makers' in your town.
