Sep 16, 2020018332The casting process would be done by making a sand mold of the piece to be added. Once the mold was made you simply put it on top of the metal piece you wanted to add a part to, and fill it with hot molten metal, after which you wait for it to cool. Another way metal was joined was by putting two pieces of metal together and damming any open sides.
Sand. Sand, a basic component of soil, ranges in particle size from 0.05mm to 2.0mm in diameter. Fine sands 0.05mm 0.25mm do little to improve the physical properties of a growing media and may result in reduced drainage and aeration. Medium and coarse sand particles are those which provide optimum adjustments in media texture.
